The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 13, short of 90°F on every date, while 156 dates carry a normal low at or below freezing, the coldest 9°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into April 3, then returns to freezing around October 31, covering 156 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
September 30 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Guthrie Ctr runs a summer-peaked wet season
38% of Guthrie 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 May at 5.3", on a wide 54.5°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.
- Wettest three months: May, June, August, taking 41% of the annual total between them.
- Driest month: January at 0.9".
- Winter share: 9% 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 Guthrie Ctr's climate pattern fits together
heating led · moderate · mid swing
Guthrie Ctr's energy balance leans toward cold weather: 6,849 annual heating degree days against 843 for cooling. Its 54.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Guthrie Ctr's frost-free season lasts about 154 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 Guthrie Ctr's middle-range seasonal profile. The measured spread is 54.5°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Guthrie Ctr's 37.1 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Guthrie 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 Guthrie 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 Guthrie Ctr's primary station: GUTHRIE CTR (USC00133509). 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 Guthrie Ctr; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Guthrie Ctr comes from its primary NOAA station record.
