San Diego Montgomery Fld receives roughly 11.0 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate. For energy use, 1,320 heating degree days and 1,019 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, San Diego Montgomery Fld scores 77/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows, shoulder seasons for mild highs and lows, peak summer for August-driven heat, or deep winter for December-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
