The year, day by day

Summer here tops out rather than builds: the warmest normal high is 75°F around July 21, short of 90°F on every date, while 188 dates carry a normal low at or below freezing, the coldest -2°F near January 26.

The freezing stretch

The normal low stays at or below 32°F into April 26, then returns to freezing around October 22, 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.

Where the wet dates fall

The likeliest wet date is December 12, when 58% of years recorded at least a hundredth of an inch. The driest is September 14 at 38%. Summed across the calendar, that is about 178 wet dates a year.

The widest day

May 26 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Limestone 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.

Limestone spreads its precipitation across the year

Neither half of the year dominates here: June through August take 28% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Limestone has no dry season to plan around, though it does carry a wide 54.9°F gap between its warmest and coldest month.

The gap between the wettest and driest month still matters: July averages 4.1" and February 2.6". The three wettest months together take 28% of the year, against the 25% a perfectly flat distribution would give them.

Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.

How Limestone's precipitation splits across the calendar

About 179 days a year record measurable precipitation here, carrying 43.1" between them, or roughly 0.24 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.

How Limestone's climate pattern fits together

heating led · moderate · mid swing

Limestone's energy balance leans toward cold weather: 9,724 annual heating degree days against 131 for cooling. Its 54.9°F seasonal range still makes the monthly rows more useful than the annual average alone.

Only about 131 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 Limestone's middle-range seasonal profile. The measured spread is 54.9°F. The annual average is 39°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Limestone's 43.1 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.

These labels group NOAA 1991-2020 normals from Limestone'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 Limestone, not an official NOAA class or a year-ahead forecast.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 2339265), not an incorporated municipality. Match rule for Limestone: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
