Warming context for E Mesa

Methodology

E Mesa'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.

Climate Guides

Climate Insight: E Mesa, AZ

An annual average temperature of 72°F, ranging from a mean daily high of 87°F to a mean daily low of 58°F is what the NOAA 1991–2020 climate normals report for E Mesa, Arizona. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00022782 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. E Mesa sees about 10.8 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 312 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 1 and the first fall freeze near December 10. On the energy side, 1,253 heating degree days and 3,931 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, E Mesa scores 85/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings December-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
