The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 16, short of 90°F on every date, while 149 dates carry a normal low at or below freezing, the coldest 16°F near January 27.
The freezing stretch
The normal low stays at or below 32°F into April 8, then returns to freezing around November 12, covering 149 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
April 29 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Hampton Stands Nationally
The normal water year runs well above the national norm at roughly 51 inches.
Hampton earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Hampton spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Hampton has no dry season to plan around, though it does carry a 43.4°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 4.8" and February 3.4". The three wettest months together take 28% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.

Data-derived climate profile
How Hampton's climate pattern fits together
heating led · wet · mid swing
Hampton's energy balance leans toward cold weather: 6,396 annual heating degree days against 436 for cooling. Its 43.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Hampton's frost-free season lasts about 168 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Hampton's middle-range seasonal profile. The measured spread is 43.4°F. The annual average is 49°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Hampton carries 50.6 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Hampton's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Hampton, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Hampton's primary station: HAMPTON (USC00063420). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Hampton; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Hampton comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
