Where Deadhorse Stands Nationally

Winters bite deep and often: the normal nightly low dips to freezing or below on around 273 nights a year, placing this among the most frost-prone tenth of ranked stations.

Aridity defines the water calendar: about 6 inches in a normal year lands this among the driest tenth of ranked stations.

Deadhorse earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Deadhorse runs a summer-peaked wet season

52% of Deadhorse'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 1.4", on a wide 62.2°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.

Scarce-water calendar

Where Deadhorse's limited precipitation lands

heating led · dry · high swing

Winter and seasonal range jointly define this record. Deadhorse logs 18,823 heating degree days, more than twice its 0 cooling total, while the typical coldest-to-warmest-month gap reaches 62.2°F. The annual mean therefore compresses two materially different seasons.

A frost-free growing-season length is not available for Deadhorse. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.

July and January mark the typical warm and cold ends of the calendar in this dry, high-range record. The gap is 62.2°F, so a single annual figure is especially lossy; the annual average is 13°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Deadhorse.

Deadhorse's cold-season load does not imply a wet climate. Annual precipitation is 5.7 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.

February is typically driest; arid stations are defined by when water is absent, not by a four-season grid.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Deadhorse's primary station: DEADHORSE AP (USW00027406). 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 Deadhorse; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
