The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 25, short of 90°F on every date, while 134 dates carry a normal low at or below freezing, the coldest 20°F near January 7.
The freezing stretch
The normal low stays at or below 32°F into March 20, then returns to freezing around November 8, covering 134 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 June 3, when 24% of years recorded at least a hundredth of an inch. The driest is December 11 at 9%. Summed across the calendar, that is about 59 wet dates a year.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Hart Stands Nationally
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.

Hart runs a summer-peaked wet season
40% of Hart'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 2.6", on a 40°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: June, May, August, taking 42% of the annual total between them.
- Driest month: February at 0.5".
- 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.
How Hart's precipitation splits across the calendar
About 59 days a year record measurable precipitation here, carrying 17.7" between them, or roughly 0.30 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 Hart, but rarely amounts to much
The normals record 6.2 inches of snow a year here, most likely in February. 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.

Data-derived climate profile
How Hart's climate pattern fits together
heating led · dry · mid swing
Hart's energy balance leans toward cold weather: 4,415 annual heating degree days against 1,117 for cooling. Its 40.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Hart's frost-free season lasts about 182 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 Hart's middle-range seasonal profile. The measured spread is 40.0°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Hart's cold-season load does not imply a wet climate. Annual precipitation is 17.7 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 6.2 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Hart'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 Hart, not an official NOAA class or a year-ahead forecast.
