Climate Insight: Winters, CA
Based on station USC00049742 feeding NOAA's 1991–2020 climate normals, Winters, California averages 63°F a year, ranging from a mean daily high of 77°F to a mean daily low of 49°F. July is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Beyond temperature, Winters averages 23.8 inches of precipitation annually, with negligible snowfall - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 285 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 18 and the first fall freeze near November 30. Turning to energy use, 2,392 heating degree days and 1,541 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Winters scores 97/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
