Climate Insight: Lake Solano, CA
Based on station USC00044712 feeding NOAA's 1991–2020 climate normals, Lake Solano, 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.
Anyone planning to live, garden, or travel in Lake Solano should weigh precipitation alongside temperature: the annual average runs an uncharted amount, predominantly as rainfall. The frost-free season averages 304 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 4 and the first fall freeze near December 5. And on the energy front, 2,357 heating degree days and 1,596 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Lake Solano scores 80/100 (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.
