Climate Insight: Lompoc, CA

September 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.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Lompoc receives roughly 15.4 inches of precipitation each year, with negligible snowfall. The frost-free season averages 333 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 20 and the first fall freeze near December 19. For energy use, 2,248 heating degree days and 168 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Lompoc scores 80/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings September-driven heat, and deep winter brings December-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
