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.

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.
