Overton's normals sit in a dry climate class: BWh
Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as hot desert (BWh). Class BWh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot desert.

The year, day by day
Overton works both ends of the calendar. Normal highs climb to 110°F by July 14 and hold at or above 90°F on 152 dates, then normal lows drop to freezing or below on 17 dates, bottoming at 32°F around December 18.
When the heat sits
Normal highs reach 90°F from May 9 through October 7, covering 152 dates. The broader mild season, normal highs of 70°F or more, runs February 28 to November 18.
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
Freezing normal lows set in around December 15, covering 17 dates.
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 February 19, when 15% of years recorded at least a hundredth of an inch. The driest is June 12 at 2%. Summed across the calendar, that is about 28 wet dates a year.
The widest day
June 18 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Overton Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 152 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 6 inches in a normal year lands this among the driest tenth of ranked stations.
Overton earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Overton's wet season runs through the cold months
December, January and February carry 40% of the year's precipitation here, while June through August contribute 16%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a wide 45.6°F gap between its warmest and coldest month.
- Wettest month
- February, 0.9"
- Driest month
- June, 0.1"
- Wettest three months
- February, March, January (43% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Overton's precipitation splits across the calendar
About 27 days a year record measurable precipitation here, carrying 5.6" between them, or roughly 0.20 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.
Overton's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Scarce-water calendar
Where Overton's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 5.6 inches annually, within PlainClimate's dry band. Recorded annual snowfall is negligible. The monthly distribution matters because the total alone does not reveal the timing.
July and December mark the typical warm and cold ends of the calendar in Overton's middle-range seasonal profile. The measured spread is 45.6°F. The annual average is 69°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Overton's normal, at 2,067 and 3,443 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
Overton has a long frost-free window of roughly 269 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Overton's primary station: OVERTON (USC00265846). 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 Overton; 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 Overton comes from its primary NOAA station record.
