What Williamsburg's climate means for you
Williamsburg runs 60°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USC00449151 feeding NOAA's 1991–2020 climate normals, Williamsburg, Virginia averages 60°F a year, ranging from a mean daily high of 69°F to a mean daily low of 50°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.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Williamsburg receives roughly 51.2 inches of precipitation each year, with 4.3 inches typically falling as snow. The frost-free season averages 224 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 31 and the first fall freeze near November 10. For energy use, 3,491 heating degree days and 1,585 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Williamsburg scores 73/100 (Good), 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 July-driven heat, and deep winter brings January-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.
