A genuine cold semi-arid continental climate

Yakima's climate is classified as cold semi-arid (Köppen BSk): hot, dry summers and short, very cold, snowy winters. August, the warmest month, averages an 86.5°F high; January, the coldest, averages only 37.6°F -- a real, stark seasonal swing distinct from Western Washington's mild, marine pattern.

Genuinely dry -- even drier than Spokane

Yakima receives only about 11 inches of precipitation per year -- genuinely drier than Spokane's own documented 19 inches, and dramatically drier than Olympia's 56 inches or Bellingham's 37-42 inches.

Real winter snow and cold

Yakima averages 18 inches of snow per year, with temperatures rarely dropping below 10°F or exceeding 99°F -- a real, genuine four-season climate with meaningful winter cold, not a mild year-round pattern.

Roughly 199 sunny days per year

Yakima sees roughly 199 sunny days per year -- a real, genuine contrast to Western Washington's gray winters, a draw for movers specifically seeking more sunshine and four-season variety over marine-climate gray.
