Harrisonburg weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Dale Enterprise (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Harrisonburg are April through November: 8 of 12. Outside them, January, February, March and December have an average overnight low at or below freezing (32°F).
In January, February, March and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 123 days a year with a low at or below 32°F at this station.
Harrisonburg gets about 39 inches of precipitation in a normal year, including roughly 19 inches of snow. The wettest months are May, June and July (4.1 inches in July). Inside the workable window, October and November are the driest, at 2.5 and 2.6 inches. The station averages about 21 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
