Portland Weather
Every season in Portland brings unique weather conditions and changes to the city's outdoor scenery.
With four distinct seasons, Portland’s outdoor scenery and weather conditions transform every few months. Though the city’s weather is perhaps best known for being rainy, showers are typically gentle and short-lived — and locals don’t let that keep them from enjoying the city.
In fact, Portlanders know the rain is what nourishes the city’s abundance of public gardens, urban green spaces and wildlife preserves — all of which can be enjoyed year-round. So whether you’re visiting during the peak of summer or in the middle of winter, a trip to Portland is guaranteed to offer uniquely seasonal sights, delicious food and seemingly endless things to do (check out our events calendar to discover more).
