What Concord Wwtp's climate means for you
Concord Wwtp runs 62°F a year - peaking in August, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
An annual average temperature of 62°F, ranging from a mean daily high of 74°F to a mean daily low of 51°F is what the NOAA 1991–2020 climate normals report for Concord Wwtp, California. August is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00041967 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. Concord Wwtp sees about 17.7 inches of precipitation a year, with negligible snowfall. The frost-free season averages 346 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 7 and the first fall freeze near December 19. On the energy side, 2,029 heating degree days and 1,084 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Concord Wwtp scores 90/100 (Excellent), 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.
