The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 23, short of 90°F on every date, while 187 dates carry a normal low at or below freezing, the coldest 0°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 18, covering 187 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 14, when 40% of years recorded at least a hundredth of an inch. The driest is November 27 at 15%. Summed across the calendar, that is about 91 wet dates a year.
The widest day
September 6 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Jamestown Muni Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 187 nights a year, more than most ranked stations.

Jamestown Muni runs a summer-peaked wet season
47% of Jamestown Muni'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 July at 3.6", on a wide 59.6°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: July, June, May, taking 51% of the annual total between them.
- Driest month: January at 0.3".
- Winter share: 5% 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 Jamestown Muni's precipitation splits across the calendar
About 91 days a year record measurable precipitation here, carrying 19.8" 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 Jamestown Muni's climate pattern fits together
heating led · dry · high swing
Winter and seasonal range jointly define this record. Jamestown Muni logs 9,010 heating degree days, more than twice its 419 cooling total, while the typical coldest-to-warmest-month gap reaches 59.6°F. The annual mean therefore compresses two materially different seasons.
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 this dry, high-range record. The gap is 59.6°F, so a single annual figure is especially lossy; the annual average is 41°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Jamestown Muni.
Jamestown Muni's cold-season load does not imply a wet climate. Annual precipitation is 19.8 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 Jamestown Muni'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 Jamestown Muni, 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 Jamestown Muni's primary station: JAMESTOWN MUNI AP (USW00014919). 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 Jamestown Muni; 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 Jamestown Muni comes from its primary NOAA station record.
