The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 27, short of 90°F on every date, while 188 dates carry a normal low at or below freezing, the coldest 6°F near January 9.
The freezing stretch
The normal low stays at or below 32°F into April 19, then returns to freezing around October 15, covering 188 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 12 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Zeona Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 188 nights a year, more than most ranked stations.
Zeona earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Data-derived climate profile
How Zeona's climate pattern fits together
heating led · mid swing
Zeona's energy balance leans toward cold weather: 7,896 annual heating degree days against 645 for cooling. Its 54.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 140 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Zeona's middle-range seasonal profile. The measured spread is 54.5°F. The annual average is 45°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Zeona's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Zeona'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 Zeona, 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 Zeona's primary station: ZEONA 10 SSW (USC00399537). 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 Zeona; 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 Zeona comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
