Which months are mildest at N?

Normal highs sit between 65°F and 85°F in April, May, June, July, August, September and October. Of those, September has the fewest days with rain (8).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost at N?

In N, the last spring frost (32°F) comes after April 1 in half of years and after April 15 in one year in ten; the first autumn frost comes before November 10 in half of years and before October 31 in one year in ten.

First autumn frost, half of years before
November 101 year in 10 before October 31; 9 in 10 before November 26

NOAA puts the median frost-free season at 223 days, and the season without a hard freeze (28°F) at 247 days.

A hard freeze (28°F) comes after March 21 in half of springs and before November 23 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts N in zone 8a in ZIP code 23128, the nearest ZIP area.

How many heating and cooling degree days does N record?

A normal year at N brings 3,944 heating degree days, 27% fewer than the median U.S. place (5,373), and 1,287 cooling degree days, 42% more than the median (908). Five months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 4,148 growing degree days a year above 50°F.

Have recent years at N been warmer than normal?

2025 averaged 59.6°F, 2.0°F above the 1991-2020 normal of 57.6°F. 5 of the 5 complete years since 2021 ran warmer than the normal.

How does N's climate compare?

N is warmer than 54 of the 81 places with their own NOAA record in Virginia, and wetter than 71. Across the 7,247 U.S. stations with normals, its annual mean of 57.6°F is warmer than 68%.

In the Köppen classification computed from these normals, N is Cfa: temperate, no dry season, hot summer. What the classes mean.

Which places near N share this climate record?

8 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
