The year, day by day
Roswell Climat works both ends of the calendar. Normal highs climb to 95°F by June 21 and hold at or above 90°F on 88 dates, then normal lows drop to freezing or below on 117 dates, bottoming at 22°F around January 1.
When the heat sits
Normal highs reach 90°F from May 30 through August 25, covering 88 dates. The broader mild season, normal highs of 70°F or more, runs March 18 to October 31.
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 March 8, then returns to freezing around November 13, covering 117 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 September 4, when 21% of years recorded at least a hundredth of an inch. The driest is April 1 at 6%. Summed across the calendar, that is about 42 wet dates a year.
The widest day
April 3 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Roswell Climat Stands Nationally
Aridity defines the water calendar: about 12 inches in a normal year lands this among the driest tenth of ranked stations.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 88 days a year, more than four out of five ranked stations record.

Roswell Climat runs a summer-peaked wet season
37% of Roswell Climat'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 1.9", on a 40.4°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 44% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 12% 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 Climat's precipitation splits across the calendar
About 43 days a year record measurable precipitation here, carrying 11.6" between them, or roughly 0.27 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 Climat, but rarely amounts to much
The normals record 9.8 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 4 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.

Where Roswell Climat's limited precipitation lands
heating led · dry · mid swing
Roswell Climat's energy balance leans toward cold weather: 3,611 annual heating degree days against 1,597 for cooling. Its 40.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Roswell Climat's frost-free season lasts about 200 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 Roswell Climat's middle-range seasonal profile. The measured spread is 40.4°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Roswell Climat's cold-season load does not imply a wet climate. Annual precipitation is 11.6 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 9.8 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

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