Rejoice, Portlanders — the spring equinox is Tuesday, March 19, and with that, the promise of warmer days, blossoming landscapes, and yes (takes deep sigh) pollen. Personally, we think the weather is an underrated conversation topic, so we peeked at some of the major weather trends headed our way over the next few months.

Here’s what you can expect this spring in the City of Roses and beyond based on predictions from the National Oceanic and Atmospheric Administration’s Climate Prediction Center.

Feeling hot, hot, hot. In Portland, there’s a 70-80% chance of temps being warmer than usual this spring. That trend is reflected in most of the northern half of the US, but the odds are most likely in the PNW (see the red above).

A map of the United States shows the seasonal precipitation outlook for March, April, and May 2024. Portland has a 33-40% chance of experiencing less precipitation.

There will be rain this spring, but chances are that it will be less than usual.

We’re not saying to put away your galoshes just yet... but sandal season could be in effect sooner than you think. Our region has a 33-44% chance of getting less precipitation than usual.


Despite experiencing less rain, Portland and its surroundings are predicted to be free from drought through May 31.

March comes in like a lion

Bad news: the average rainfall for this month is 3.68 inches, but the good news is that conditions should start to improve as we... ahem... march... toward drier days and peak cherry blossoms.

April showers us with allergens

Trees typically start to release more pollen around this time, meaning runny noses and red eyes. Start up that medicine regimen so you don’t miss out on the Wooden Shoe Tulip Festival. Average overnight low temperatures hover around 44°, so it’s also time to start your garden.

May is moving the needle

We’ll always give this month its flowers. From the Portland Rose Festival to the Mt. Tabor Art Walk, there are plenty of outdoor events and for good reason; on average, we experience 276 hours — or 11.5 days — of sunshine.
