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 40°F around January 24.

Where the wet dates fall

The likeliest wet date is August 1, when 39% of years recorded at least a hundredth of an inch. The driest is May 8 at 30%. Summed across the calendar, that is about 126 wet dates a year.

The widest day

April 3 carries the biggest normal gap between afternoon and dawn, 16°F between the normal high and the normal low.

Where Cape Hatteras Stands Nationally

This is one of the wettest normals climates ranked: about 61 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.

Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 16°F.

Cape Hatteras earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Cape Hatteras spreads its precipitation across the year

Neither half of the year dominates here: June through August take 27% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Cape Hatteras has no dry season to plan around, though it does carry a 33.3°F seasonal spread.

The gap between the wettest and driest month still matters: September averages 7.6" and April 3.9". The three wettest months together take 33% 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.

When it rains in Cape Hatteras, it arrives in quantity

61.2" of precipitation falls across only about 125 wet days here, averaging 0.49 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile

How Cape Hatteras's climate pattern fits together

mixed demand · wet · mid swing

Water is prominent even though neither heating nor cooling wholly defines the record. Cape Hatteras averages 61.2 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.

July and January mark the typical warm and cold ends of the calendar in Cape Hatteras's middle-range seasonal profile. The measured spread is 33.3°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Cape Hatteras's normal, at 2,168 and 2,127 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 293 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.

These labels group NOAA 1991-2020 normals from Cape Hatteras'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 Cape Hatteras, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Cape Hatteras's primary station: CAPE HATTERAS AP (USW00093729). 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 Cape Hatteras; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
