Pacific Northwest in January

Summer is prime time—June through September delivers the famous dry weather everyone talks about. July and August see the least rain, but also the biggest crowds and highest prices. June offers a sweet spot with longer days and fewer tourists. September extends the good weather while kids return to school. The shoulder seasons have their charms too. May brings blooming rhododendrons and fewer crowds, though pack rain gear. October showcases fall colors, especially in the Columbia River Gorge. Winter isn't a write-off if you embrace the rain. December through February means cozy coffee shops, fewer tourists, and storm watching on the coast. Just know that mountain passes can close due to snow, limiting access to places like Mount Rainier. Spring arrives early here—February often brings the first cherry blossoms in Portland and Seattle. But the weather stays unpredictable until May, so layers become your best friend.
