Climate Insight: Boston, VA
The NOAA 1991–2020 climate normals describe Boston, Virginia as a location with an annual average temperature of 54°F, ranging from a mean daily high of 66°F to a mean daily low of 43°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00440860, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Boston receives roughly an uncharted amount of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 21 and the first fall freeze near October 22. For energy use, 4,837 heating degree days and 936 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Boston scores 52/100 (Moderate), 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 July-driven heat, or deep winter for January-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.
