The year, day by day
Roswell Ind Air Park works both ends of the calendar. Normal highs climb to 97°F by June 21 and hold at or above 90°F on 109 dates, then normal lows drop to freezing or below on 77 dates, bottoming at 27°F around January 1.
When the heat sits
Normal highs reach 90°F from May 22 through September 7, covering 109 dates. The broader mild season, normal highs of 70°F or more, runs March 14 to November 4.
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.
The freezing stretch
The normal low stays at or below 32°F into February 12, then returns to freezing around November 28, covering 77 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.
Where the wet dates fall
The likeliest wet date is August 4, when 23% of years recorded at least a hundredth of an inch. The driest is April 10 at 8%. Summed across the calendar, that is about 51 wet dates a year.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Roswell Ind Air Park Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 109 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 12 inches in a normal year lands this among the driest tenth of ranked stations.
Roswell Ind Air Park earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Roswell Ind Air Park runs a summer-peaked wet season
41% of Roswell Ind Air Park'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 July at 1.8", on a 40.8°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: July, August, September, taking 43% of the annual total between them.
- Driest month: February at 0.3".
- Winter share: 11% 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.
How Roswell Ind Air Park's precipitation splits across the calendar
About 51 days a year record measurable precipitation here, carrying 11.6" between them, or roughly 0.23 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Snow reaches Roswell Ind Air Park, but rarely amounts to much
The normals record 9.6 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 5 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Scarce-water calendar
Where Roswell Ind Air Park's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 11.6 inches annually, within PlainClimate's dry band. Annual snowfall totals 9.6 inches. The monthly distribution matters because the total alone does not reveal the timing.
July and December mark the typical warm and cold ends of the calendar in Roswell Ind Air Park's middle-range seasonal profile. The measured spread is 40.8°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Roswell Ind Air Park's normal, at 2,876 and 2,236 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.
A roughly 223-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.

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 Roswell Ind Air Park; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
