When the heat sits

Normal highs reach 90°F from June 24 through August 24, covering 62 dates. The broader mild season, normal highs of 70°F or more, runs March 12 to November 11.

This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.

No freezing date

Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 36°F around January 13.

The widest day

April 13 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Data-derived climate profile

How Ashburn's climate pattern fits together

mixed demand · mid swing

July and January mark the typical warm and cold ends of the calendar in Ashburn's middle-range seasonal profile. The measured spread is 33.1°F. The annual average is 66°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Ashburn's normal, at 2,002 and 2,245 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.

The frost-free window extends for about 254 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.

A moisture-range label is withheld because Ashburn's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.

These labels group NOAA 1991-2020 normals from Ashburn's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Ashburn, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Ashburn's climate

How many days above 90°F does Ashburn get?
Ashburn averages about 74 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Ashburn?
Ashburn has 2,002 heating degree days and 2,245 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Ashburn's primary station: ASHBURN 3 ENE (USC00090406). For informational purposes only.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 1303236). Match rule for Ashburn: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
