Warming context for Redlands
MethodologyRedlands'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.
- United States land mean (NOAA NCEI) +0.11 °C/decade
- Global anomaly (NASA GISTEMP) +0.11 °C/decade
- Paris Agreement thresholds 1.5°C / 2.0°C

August is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00047306, 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. Redlands receives roughly 12.9 inches of precipitation each year, with negligible snowfall. The frost-free season averages 326 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 27 and the first fall freeze near December 19. For energy use, 1,647 heating degree days and 1,751 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Redlands scores 90/100 (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 August-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.
