Warming context for Wallace

Methodology

Wallace's NOAA 1991-2020 normal sits inside a longer story: U.S. land temperatures have been tracking (and drifting from) the global mean since 1900, and the chart below shows that spread, with the most recent decade running warmer than the 30-year mean.

Wallace averages 37.2 inches of precipitation a year, with 75.6 inches typically falling as snow, and that matters as much to daily life here as temperature does. The frost-free season averages 150 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 5 and the first fall freeze near October 2. As for energy demand, 7,144 heating degree days and 238 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Wallace scores 54/100 (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 July-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.
