About the Region

Pacific Northwest

The Pacific Northwest occupies a unique niche in American geography — major cities set against volcanic peaks, temperate rainforests, and wild coastline that remain accessible without leaving the metro area. Seattle has become one of the most globally significant tech cities, anchor to Amazon, Microsoft, and a dense ecosystem of aerospace and cloud computing. Portland's creative culture and compact geography made it a darling of the livability rankings, though the city has faced real urban challenges in recent years around homelessness and downtown vitality.

The signature trade-off is the weather. Winters are mild but persistently grey and wet — the sun doesn't return in full force until June — and those who move from sunnier climates often underestimate how the darkness affects daily mood. Those who adapt find the summers genuinely spectacular: reliably dry, long, and set against a landscape of extraordinary beauty. Secondary cities — Bend, Spokane, Eugene, Bellingham — offer more affordable entry points into the Pacific Northwest lifestyle with less urban density.
