Climate Insight: Yakima Air Terminal, WA

The NOAA 1991–2020 climate normals describe Yakima Air Terminal, Washington as a location with an annual average temperature of 51°F, ranging from a mean daily high of 64°F to a mean daily low of 37°F. July is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USW00024243, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Yakima Air Terminal receives roughly 8.0 inches of precipitation each year, with 20.3 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 8 and the first fall freeze near October 4. For energy use, 5,756 heating degree days and 606 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Yakima Air Terminal scores 42/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for December-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
