Planning notes for Spokane

For anyone relocating: average overnight lows drop below freezing in 5 months (January, February, March, November, December), so heating, winter tires, and pipe protection are real seasonal concerns; highs reach the 80s on average in 2 months, but 90°F average highs never arrive; 5 months of the year average between 55°F and 80°F, the band most people find comfortable without heating or cooling. Those four facts, all straight from the normals table above, shape everything from a Spokane wardrobe to its utility bills.
