Best Time to Visit Portland, Oregon: Month-by-Month Weather and Events

The best time to visit Portland, Oregon is from July to mid-September, when the rain almost stops: July averages half an inch over fewer than four days, and highs sit around 80°F. For good weather with fewer crowds and lower hotel prices, aim for late May and June or mid-September to early October. November through February is the cheapest and the wettest stretch, and it has its own reasons to come: a free winter light festival in February, the zoo’s holiday lights and the lowest room rates of the year.

This guide is for anyone choosing dates, with the numbers that matter: NOAA’s 1991-2020 climate normals for Portland International Airport, month by month, plus the year’s recurring events. The caveat is that Portland’s rain is about frequency, not volume, and summer carries its own risks in heat waves and wildfire smoke. Event dates below are marked with their year, because they change; everything was checked September 24, 2026 against the organizers’ and agencies’ own websites.

When is the best time to visit Portland?

It depends on what you’re trading. Summer buys dry weather at peak prices; the shoulder seasons buy value and color with some rain; winter buys the lowest prices and short, wet days. Here’s the quick version by goal.

If you want Go in Why The trade-off
Dry, warm weather July and August About half an inch of rain a month and highs near 82°F Peak hotel prices; heat and smoke risk
Good weather, fewer crowds Mid-September Highs near 77°F, under seven rain days Summer permits and festivals are over
Roses and festivals Late May and June Rose Festival season; the Rose Garden in bloom Festival crowds; June still has about nine rain days
Fall color and harvest October Japanese Garden color, pumpkins, wine harvest Rain returns, about 13 days a month
Spring blossoms and waterfalls Late March and April Cherry blossoms downtown; waterfalls running high Frequent showers
The lowest prices November to February (outside the holidays) Low season for hotels The wettest, darkest months
A winter event February The free Winter Light Festival (February 5-13, 2027) Cold, damp evenings

Verdict: for a first visit, the second and third weeks of September are hard to beat. The weather is still summer, the kids are back in school, and hotel prices start to ease. If you can only come in winter, come in February for the light festival and plan around museums and waterfalls.

What is Portland’s weather like by month?

These are NOAA’s 1991-2020 normals for Portland International Airport, the city’s official weather station. The rain-days column counts days with at least a hundredth of an inch, which is why it matters more than the totals: Portland’s winter rain comes as frequent light rain and drizzle rather than downpours. Sunshine hours come from an older NOAA series and show how dark the winter months are.

Month Average high Average low Rain (inches) Rain days Sunshine hours
January 47.5°F 36.2°F 5.03 18.7 86
February 51.5°F 36.8°F 3.68 15.7 116
March 56.8°F 39.7°F 3.97 17.8 191
April 62.0°F 43.7°F 2.89 17.4 221
May 69.3°F 49.4°F 2.51 13.2 276
June 74.3°F 54.1°F 1.63 9.2 290
July 81.9°F 58.5°F 0.51 3.7 332
August 82.3°F 58.9°F 0.54 3.6 298
September 76.7°F 54.1°F 1.52 6.7 236
October 64.4°F 46.7°F 3.42 13.5 152
November 53.5°F 40.6°F 5.45 18.3 79
December 46.9°F 36.2°F 5.77 19.2 64

The whole year adds up to 36.92 inches of rain over about 157 days, less total rain than many East Coast cities but spread across far more days. Snow averages just 4.2 inches a year, mostly in December, January and February, and some winters see almost none; when it does fall, or when freezing rain coats the hills, the city slows down fast. The extremes are the exception, not the rule: the airport’s record high is 116°F, set in the June 2021 heat wave, and its record low is minus 3°F.

Portland month by month

January

January is cool, gray and wet, with highs averaging 47.5°F, rain on about 19 days and only about 86 hours of sunshine all month. It’s also the quietest and usually the cheapest month for hotels outside the holidays. The Oregon Zoo’s ZooLights runs through January 3 in the 2026-27 season, and after that the city settles into museum weather: OMSI, the Portland Art Museum, Powell’s and the Lan Su teahouse all work well in the rain, and the Japanese Garden is striking in winter mist. Out of town, Mount Hood’s ski season is in full swing, and the Gorge’s waterfalls run high.

Verdict: good for a budget city break built around indoor sights and good food. Pack a real rain shell.

February

February is slightly drier than January (3.68 inches over about 16 days) and a little brighter, and it has the winter’s best event. The Portland Winter Light Festival, a free, citywide show of light installations and art, runs February 5 to 13 in 2027 (it ran February 6 to 14 in 2026). It’s the reason to choose February over any other winter month. Hotel prices stay in low-season territory, and the city’s restaurants and theaters are busy with locals rather than visitors.

March

March warms to an average high of 56.8°F but keeps the rain, with about 18 wet days. Late in the month, the cherry trees along Tom McCall Waterfront Park burst into bloom, usually peaking in late March or early April, and the city starts to come outside. Oaks Park’s rides reopen in mid-March, and the Columbia River Gorge’s waterfalls are at their fullest. Spring break brings a bump in family travel, so book central hotels a little earlier than for February.

April

April is the month of showers: only 2.89 inches of rain, but spread over about 17 days, often with sun in between. Highs reach 62°F, and the city is green, blooming and still uncrowded. Crystal Springs Rhododendron Garden in Southeast comes into its own in spring, the Gorge’s waterfalls stay strong, and wildflowers start along its trails. It’s a good month for visitors who don’t mind carrying a jacket and want spring color without summer prices.

May

May is when Portland starts to feel like summer, at least between showers: highs average 69.3°F, rain falls on about 13 days, and the days stretch past 8 p.m. The Portland Rose Festival usually begins in late May (in 2026 it ran May 22 to June 28), and the International Rose Test Garden, free and open daily, blooms from late May into October. The Multnomah Falls timed-entry permit season also starts in late May (May 22 in 2026), so book a slot on Recreation.gov for the I-84 lot. Basketball fans can catch the Portland Fire, the WNBA team that debuted at the Moda Center in May 2026.

June

June is warm and long, with highs of 74.3°F, about nine rain days and sunsets around 9 p.m. near the solstice. Rose Festival season peaks: the 2026 festival merged its Grand Floral and Starlight parades into a single parade on Saturday, June 6, at 6:30 p.m., with CityFair weekends on the waterfront. The Rose Garden is at its fullest. The month’s weather can swing, with a few gray, showery days early on, so don’t assume full summer until the Fourth of July.

July

July is Portland at its best and busiest. It’s the sunniest month, with about 332 hours of sunshine, rain on fewer than four days and highs averaging 81.9°F. The Waterfront Blues Festival fills Tom McCall Waterfront Park over the Fourth of July (July 2 to 4 in 2026), with children 12 and under free alongside a paying adult. Everything outdoors is open: river beaches, Mount Hood’s trails, the coast, the Gorge. The catch is price and demand, since this is peak season for hotels, and occasional heat waves, when afternoons can climb well past the average.

Verdict: the safest month for weather. Book rooms and Multnomah Falls permits early, and plan hot afternoons around museums or the river.

August

August is the warmest month on average, at 82.3°F, and nearly as dry as July. It’s berry season on Sauvie Island and prime time for the coast, where the ocean keeps things cooler. Its one real risk is wildfire smoke: in some years, fires in the Cascades and beyond fill the air with haze in late summer and close trails. Check air-quality reports and the Forest Service before a hiking day, and keep a flexible plan with indoor options.

September

September is many locals’ favorite month. Highs still average 76.7°F, rain falls on fewer than seven days, and after Labor Day the summer crowds thin and hotel prices begin to ease. The Multnomah Falls permit season ended on September 7 in 2026, so the Gorge becomes easier to visit on a whim. The Willamette Valley’s grape harvest starts, and the evenings turn cool enough for a jacket. Late in the month, the first rains usually arrive, though often only as showers.

Verdict: the best balance of weather, crowds and price in the year, especially the second and third weeks.

October

October brings fall color and the return of rain, with 3.42 inches over about 13 days and highs of 64.4°F. The Portland Japanese Garden, Hoyt Arboretum and the city’s big street trees turn red and gold, Sauvie Island’s pumpkin patches open, and wine country is in harvest mode. Evening events move indoors, although the Last Thursday art walk on NE Alberta Street still runs (October 29 in 2026). Early October often keeps a run of dry days; late October is reliably wetter.

November

November is when the rainy season starts in earnest: 5.45 inches over about 18 days, highs of 53.5°F and only about 79 hours of sunshine. Hotel prices drop outside Thanksgiving week, and the city’s indoor life takes over: restaurants, bars, bookstores and theaters. ZooLights opens at the Oregon Zoo on November 20 in 2026, and from November 1 Mount Hood’s Sno-Parks require a winter parking permit. It’s a good month for a food-focused trip, with a warm restaurant to end every wet day.

December

December is the wettest and darkest month, with 5.77 inches of rain over about 19 days and just 64 hours of sunshine, but it’s also Portland’s most festive. ZooLights runs through the holidays (to January 3, 2027, on varying nights), and the Christmas Ships Parade, decorated boats cruising the Willamette and Columbia, runs on nights through December; the 2026 schedule includes a Willamette River run on Monday, December 7, from 7 to 9 p.m., and dock walks at RiverPlace Marina on December 19 and 20. The Portland Saturday Market holds its last 2026 market on December 19. One money note: Oregon’s state lodging tax rises from 1.5% to 2.75% for stays ending on or after January 1, 2027, and a stay that spans New Year’s pays the higher rate on every night.

Portland’s seasons at a glance

Season Weather Crowds and prices Highlights Watch for
Spring (March-May) Highs 57-69°F; frequent showers Moderate; rising in May Cherry blossoms, rhododendrons, waterfalls, the Rose Festival’s start Showers; spring-break bump
Summer (June-August) Highs 74-82°F; very little rain Highest The Rose Festival, the Blues Festival, beaches, mountains, long evenings Heat waves, smoke, permit systems, booked-up hotels
Fall (September-November) Highs from 77°F down to 54°F; rain returns in October Falling after Labor Day September sun, fall color, harvest, pumpkins, ZooLights from late November November rain and early dark
Winter (December-February) Highs 47-52°F; frequent light rain; rare snow Lowest, except holidays ZooLights, the Christmas Ships, the Winter Light Festival, museums Short days; occasional ice; the 2027 lodging tax increase

Daylight swings widely at this latitude: the sun sets around 9 p.m. in late June and around 4:30 p.m. in early December, which shapes a winter itinerary as much as the rain. Our Portland itineraries show how to rearrange days for rain and short daylight.

Portland events calendar

These are the recurring events that are worth building a trip around. Dates change every year, so each is shown with its usual timing and the latest confirmed dates; check the organizer before booking.

Sports add their own calendars: the Timbers and Thorns play soccer at Providence Park roughly from spring into the fall, the Trail Blazers’ NBA season runs from fall into spring at the Moda Center, and the Portland Fire’s WNBA season fills the summer there.

The best time for specific things

Most trips have a purpose beyond good weather. Here’s when each of Portland’s main draws is at its best.

For Best months Why
Gardens April-June, October Rhododendrons and roses in spring; the Japanese Garden and Hoyt Arboretum in fall color
Waterfalls November-May The Gorge and Silver Falls run fullest in the wet season
Mountain hiking July-September High trails on Mount Hood are mostly snow-free and dry
The coast July-September The calmest, driest weeks; winter is for storm watching from a safe spot
Skiing and snow play December-March Mount Hood’s season; Sno-Park permits run November 1 to April 30
Wine country September-October Harvest color and energy; spring is quieter and easier to book
Food carts and patios June-September Outdoor seating at its best; covered pods carry the rest of the year
Farmers markets May-October Peak produce, though the Saturday PSU market runs year-round
Families June-August, spring break Oaks Park’s rides (mid-March through October), long days, river beaches
Budget trips November-February The lowest room rates outside the holidays

A few of these overlap nicely. Late September gives you mountain trails, harvest in wine country and still-dry city weather in one trip, while April pairs full waterfalls with blossoms downtown. December’s pairing is ZooLights with Mount Hood’s first good snow, if the winter cooperates.

How far ahead should you book a Portland trip?

Portland rarely sells out completely, but the best-located rooms go early in a few predictable windows. Plan on:

  • Three months or more for summer weekends, the Rose Festival’s big weekends and the Blues Festival’s Fourth of July weekend.
  • Six to eight weeks for summer weekdays, September and graduation weekends in late spring.
  • A few weeks for most of October through April, outside Thanksgiving, Christmas and New Year’s.
  • A specific window for timed tickets: Portland Japanese Garden tickets open 10 days ahead, Oregon Zoo tickets 30 days ahead, and ZooLights and Multnomah Falls permits are dated, so buy them as soon as your dates are firm.

Whenever you book, compare total prices. Portland adds up to 14.5% in local lodging taxes and fees, and Oregon’s state lodging tax is 1.5% for stays ending by December 31, 2026 and 2.75% after that. Our guide to where to stay in Portland works through the full math by neighborhood.

Weekdays, weekends and holidays

The day of the week matters almost as much as the month. Downtown hotels lean on business travel, so weekend rates there can be lower than midweek, while neighborhood rentals often run the other way. Weekends bring the Portland Saturday Market and the PSU farmers market, but also the biggest crowds at the zoo, Multnomah Falls and the coast. A few sights keep weekly closures year-round: the Portland Japanese Garden is closed on Tuesdays, the art museum and OMSI on Mondays, and the Aerial Tram doesn’t run on Sundays.

Holidays shift the picture again:

  • Memorial Day weekend marks the start of summer, with the Rose Festival and, in recent years, the Multnomah Falls permit season beginning around the same time.
  • The Fourth of July brings the Waterfront Blues Festival and the year’s fullest waterfront.
  • Labor Day closes the summer season; in 2026 it was also the last day of Multnomah Falls timed entry, September 7.
  • Thanksgiving (November 26, 2026) closes the Oregon Zoo and many businesses for the day, and the following weekend starts the holiday season downtown.
  • Christmas to New Year’s is busy with local holiday events and visiting families; book ahead, and remember the 2027 lodging tax change for stays that end after January 1.

When is the worst time to visit Portland?

For most visitors, November through January. Rain falls on 18 or 19 days a month, the sun sets before 5 p.m., and outdoor sights lose much of their appeal. That said, “worst” depends on the trip. A museum-and-restaurant break in December, with ZooLights and the Christmas Ships, can be a very good trip, and it costs much less than the same days in July.

Summer has its own bad weeks. Heat waves can push the city far past its average highs, as the June 2021 heat wave did when the airport hit 116°F, and wildfire smoke can close trails and gray out the Gorge in late summer. And if crowds bother you more than rain, avoid the Rose Festival’s parade weekend and the Fourth of July weekend, when downtown hotels and the waterfront are at their fullest.

How to read a Portland weather forecast

Portland’s forecasts can look gloomier than the days turn out. A few local patterns help:

  • A “chance of rain” is often drizzle. Many wet winter days bring hundredths of an inch, not a downpour. A hood and a plan to duck indoors now and then usually beat canceling plans.
  • Showers come and go. In spring especially, sun and showers alternate through the day. Keep outdoor plans flexible by the hour rather than writing off the day.
  • The hills and the Gorge have their own weather. The West Hills run a little cooler and wetter than downtown, and in winter, east winds pouring out of the Columbia River Gorge can make a clear day feel far colder than the thermometer suggests.
  • The coast and the mountain are different climates. The coast is often cooler and foggier than the city in summer, and Mount Hood can hold snow while Portland sees rain. Check the forecast for where you’re going, not just the city.
  • Watch air quality in late summer. In smoke years, the air-quality index matters more than the temperature for outdoor plans.

What to pack for Portland in each season

  • All year: a light rain shell with a hood. Portlanders rarely carry umbrellas, and a hood works better in the wind on the bridges.
  • Spring and fall: layers, waterproof shoes and a warm fleece for evenings, which cool quickly even after sunny days.
  • Summer: sun protection, a refillable water bottle and one warmer layer for the coast and the mountain, which run much cooler than the city.
  • Winter: a warm, waterproof jacket, shoes that handle puddles, and traction devices and a Sno-Park permit if you’re driving to Mount Hood.

Best Time to Visit Portland, Oregon FAQ

What is the rainiest month in Portland?

December, with 5.77 inches on about 19 days in NOAA’s 1991-2020 normals, followed closely by November (5.45 inches) and January (5.03 inches). July and August are the driest, with about half an inch each over fewer than four days. Most winter rain is light and steady, so a rain shell handles it better than an umbrella.

Does it snow in Portland?

Occasionally. The airport averages 4.2 inches of snow a year, mostly in December, January and February, and some winters see almost none. When snow or freezing rain does arrive, hills get treacherous and transit slows, so allow extra time and check TriMet’s service alerts. Mount Hood, about 60 miles east, has reliable snow all winter.

Is September a good time to visit Portland?

It’s one of the best. Highs average 76.7°F, rain falls on fewer than seven days, and after Labor Day the crowds thin and hotel prices start to fall. The Multnomah Falls permit season is over, the grape harvest begins, and evenings are cool enough for a jacket. The first real rains usually arrive late in the month.

When do the roses bloom in Portland?

The International Rose Test Garden blooms from late May into October, with the fullest display usually in June, when the Rose Festival is on. The garden is free and open from 5 a.m. to 10 p.m., with more than 10,000 bushes of over 610 varieties, so an early morning visit beats the midday crowds.

What is the cheapest time to visit Portland?

November through February, outside Thanksgiving, Christmas and New Year’s, is usually the cheapest time for hotels, and airfares often dip too. Weekends downtown can also be cheaper than weekdays, when business travel fills rooms. Remember that Oregon’s state lodging tax rises to 2.75% for stays ending on or after January 1, 2027.

Is Portland worth visiting in winter?

Yes, if you plan for it. Winter brings the lowest hotel prices outside the holidays, the Winter Light Festival in February, ZooLights and the Christmas Ships in December, full waterfalls in the Gorge and snow on Mount Hood. Build days around museums, Powell’s, restaurants and short outdoor walks, and expect rain on most days rather than all day.

How much sun does Portland get?

About 2,341 hours a year in NOAA’s older 1961-1990 sunshine series, with a huge seasonal swing: July averages about 332 hours of sunshine, December about 64. Summer is reliably bright and dry, while November through January are the grayest months. If sunshine matters most to you, visit between late June and mid-September.

Is Portland hot in summer?

Usually pleasantly warm, with average highs of about 82°F in July and August and cool nights near 59°F. But heat waves do happen: the airport’s record is 116°F, set in June 2021. Many older homes and some hotels lack strong air conditioning, so check before booking a summer stay, and plan hot afternoons indoors or by the river.
