The year, day by day
The year in Beaufort Mcas runs from a mild 40°F around January 19 to 92°F at the peak near July 18, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 23 through August 20, covering 59 dates. The broader mild season, normal highs of 70°F or more, runs March 17 to November 12.
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 40°F around January 19.
Where the wet dates fall
The likeliest wet date is August 11, when 42% of years recorded at least a hundredth of an inch. The driest is November 5 at 26%. Summed across the calendar, that is about 118 wet dates a year.
The widest day
March 5 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Beaufort Mcas runs a summer-peaked wet season
38% of Beaufort Mcas's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is August at 6.5", on a 33°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: August, July, June, taking 38% of the annual total between them.
- Driest month: May at 2.5".
- Winter share: 20% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Beaufort Mcas, it arrives in quantity
45.0" of precipitation falls across only about 118 wet days here, averaging 0.38 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 118 a year, 32% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- August, about 13
- Fewest wet days
- November, about 8
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.
Beaufort Mcas's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Beaufort Mcas's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Beaufort Mcas averages 45.0 inches of precipitation a year. Recorded annual snowfall is negligible. 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 Beaufort Mcas's middle-range seasonal profile. The measured spread is 33.0°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Beaufort Mcas's normal, at 1,732 and 2,570 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 278 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 Beaufort Mcas'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 Beaufort Mcas, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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 Beaufort Mcas; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
