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.

Questions about Zeona's climate

How many days above 90°F does Zeona get?
Zeona averages about 31 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Zeona?
Zeona has 7,896 heating degree days and 645 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.

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.
