Portland in the Willamette Valley between the Coast Range and Cascades has a classic Pacific Northwest marine climate. The city is famous for its mild, rainy winters and warm, sunny summers. The 2021 Heat Dome brought temperatures to 116°F, shattering records and causing hundreds of deaths — an extreme event showing climate change impacts on a city with minimal air conditioning.
One of the most popular travel months worldwide for good reason.
