What Chula Vista's climate means for you
Chula Vista runs 63°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.
Based on station USC00041758 feeding NOAA's 1991–2020 climate normals, Chula Vista, California averages 63°F a year, ranging from a mean daily high of 71°F to a mean daily low of 56°F. August is typically the warmest month of the year, while December 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, Chula Vista averages 9.2 inches of precipitation annually, with negligible snowfall - a real factor for anyone planning to live, garden, or travel here. Growing-season length varies with elevation and microclimate. Turning to energy use, 1,305 heating degree days and 701 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Chula Vista scores 72/100 (Good), 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.
