Climate Insight: Palmer, WA
An annual average temperature of 50°F, ranging from a mean daily high of 59°F to a mean daily low of 42°F is what the NOAA 1991–2020 climate normals report for Palmer, Washington. August is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00456295 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Palmer receives roughly 85.2 inches of precipitation each year, with 17.5 inches typically falling as snow. The frost-free season averages 222 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 3 and the first fall freeze near November 11. For energy use, 5,452 heating degree days and 155 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Palmer scores 48/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings August-driven heat, and winter brings December-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
