The year, day by day
Gruver works both ends of the calendar. Normal highs climb to 94°F by July 18 and hold at or above 90°F on 66 dates, then normal lows drop to freezing or below on 132 dates, bottoming at 20°F around January 1.
When the heat sits
Normal highs reach 90°F from June 20 through August 24, covering 66 dates. The broader mild season, normal highs of 70°F or more, runs April 16 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 20, then returns to freezing around November 10, covering 132 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 July 30, when 25% of years recorded at least a hundredth of an inch. The driest is January 7 at 9%. Summed across the calendar, that is about 60 wet dates a year.
The widest day
March 28 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Gruver Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 66 days a year, more than four out of five ranked stations record.

Gruver runs a summer-peaked wet season
42% of Gruver'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 44.5°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, July, 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 Gruver's precipitation splits across the calendar
About 60 days a year record measurable precipitation here, carrying 20.6" between them, or roughly 0.35 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 Gruver, but rarely amounts to much
The normals record 11.8 inches of snow a year here, most likely in December. 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 Gruver's climate pattern fits together
heating led · moderate · mid swing
Gruver's energy balance leans toward cold weather: 4,574 annual heating degree days against 1,439 for cooling. Its 44.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Gruver's frost-free season lasts about 185 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 Gruver's middle-range seasonal profile. The measured spread is 44.5°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Gruver's 20.6 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 11.8 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Gruver'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 Gruver, not an official NOAA class or a year-ahead forecast.
