The year, day by day
Dalhart works both ends of the calendar. Normal highs climb to 94°F by July 17 and hold at or above 90°F on 70 dates, then normal lows drop to freezing or below on 135 dates, bottoming at 20°F around January 5.
When the heat sits
Normal highs reach 90°F from June 16 through August 24, covering 70 dates. The broader mild season, normal highs of 70°F or more, runs April 14 to October 22.
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 22, then returns to freezing around November 9, covering 135 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
March 24 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Dalhart Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 70 days a year, more than four out of five ranked stations record.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.
Dalhart earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Dalhart runs a summer-peaked wet season
44% of Dalhart'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 2.8", on a 44.3°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: August, July, June, taking 44% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 10% 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 Dalhart's climate pattern fits together
heating led · dry · mid swing
Dalhart's energy balance leans toward cold weather: 4,475 annual heating degree days against 1,368 for cooling. Its 44.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Dalhart's frost-free season lasts about 175 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 Dalhart's middle-range seasonal profile. The measured spread is 44.3°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Dalhart's cold-season load does not imply a wet climate. Annual precipitation is 17.5 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 Dalhart'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 Dalhart, 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 Dalhart's primary station: DALHART (USC00412238). 2 NOAA stations are mapped to the Dalhart area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 4818524). Match rule for Dalhart: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Dalhart comes from its primary NOAA station record.
