The year, day by day
Winner Wiley Fld works both ends of the calendar. Normal highs climb to 91°F by July 20 and hold at or above 90°F on 18 dates, then normal lows drop to freezing or below on 153 dates, bottoming at 14°F around January 19.
When the heat sits
Normal highs reach 90°F from July 14 through July 31, covering 18 dates. The broader mild season, normal highs of 70°F or more, runs May 14 to October 4.
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 April 2, then returns to freezing around November 2, covering 153 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 1, when 41% of years recorded at least a hundredth of an inch. The driest is January 5 at 11%. Summed across the calendar, that is about 88 wet dates a year.
The widest day
September 15 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Winner Wiley Fld runs a summer-peaked wet season
44% of Winner Wiley Fld'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 3.7", on a wide 52.4°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: June, May, August, taking 50% of the annual total between them.
- Driest month: January at 0.2".
- Winter share: 4% 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 Winner Wiley Fld's precipitation splits across the calendar
About 88 days a year record measurable precipitation here, carrying 19.5" between them, or roughly 0.22 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.

Data-derived climate profile
How Winner Wiley Fld's climate pattern fits together
heating led · dry · mid swing
Winner Wiley Fld's energy balance leans toward cold weather: 6,421 annual heating degree days against 1,062 for cooling. Its 52.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Winner Wiley Fld's frost-free season lasts about 162 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 Winner Wiley Fld's middle-range seasonal profile. The measured spread is 52.4°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Winner Wiley Fld's cold-season load does not imply a wet climate. Annual precipitation is 19.4 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 Winner Wiley Fld'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 Winner Wiley Fld, 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 Winner Wiley Fld's primary station: WINNER WILEY FLD (USW00094990). 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 Winner Wiley Fld; 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 Winner Wiley Fld comes from its primary NOAA station record.
