The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around August 2, short of 90°F on every date, while 199 dates carry a normal low at or below freezing, the coldest 0°F near January 13.
The freezing stretch
The normal low stays at or below 32°F into April 27, then returns to freezing around October 12, covering 199 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
August 11 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Dunn Ctr Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 199 nights a year, placing this among the most frost-prone tenth of ranked stations.
Dunn Ctr 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
Dunn Ctr runs a summer-peaked wet season
45% of Dunn Ctr'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 June at 3.3", on a wide 56.3°F gap between its warmest and coldest month. 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: June, May, July, taking 49% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 7% 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.

Data-derived climate profile
How Dunn Ctr's climate pattern fits together
heating led · dry · high swing
Winter and seasonal range jointly define this record. Dunn Ctr logs 8,965 heating degree days, more than twice its 389 cooling total, while the typical coldest-to-warmest-month gap reaches 56.3°F. The annual mean therefore compresses two materially different seasons.
Only about 124 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in this dry, high-range record. The gap is 56.3°F, so a single annual figure is especially lossy; the annual average is 41°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Dunn Ctr.
Dunn Ctr's cold-season load does not imply a wet climate. Annual precipitation is 16.8 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Dunn Ctr'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 Dunn Ctr, 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 Dunn Ctr's primary station: DUNN CTR 1E (USC00322365). 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 Dunn Ctr; 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 Dunn Ctr comes from its primary NOAA station record.
