The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 16, short of 90°F on every date, while 137 dates carry a normal low at or below freezing, the coldest 17°F near January 26.
The freezing stretch
The normal low stays at or below 32°F into March 31, then returns to freezing around November 16, covering 137 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 May 4, when 36% of years recorded at least a hundredth of an inch. The driest is September 1 at 27%. Summed across the calendar, that is about 118 wet dates a year.
The widest day
May 4 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Charlotteburg Rsvr spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Charlotteburg Rsvr has no dry season to plan around, though it does carry a 44.9°F seasonal spread.
The gap between the wettest and driest month still matters: October averages 5.0" and February 3.1". 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.
When it rains in Charlotteburg Rsvr, it arrives in quantity
52.2" of precipitation falls across only about 119 wet days here, averaging 0.44 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 119 a year, 32% of all days
- Average depth per wet day
- 0.44 inches
- Most wet days
- May, about 11

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Charlotteburg Rsvr's climate pattern fits together
heating led · wet · mid swing
Charlotteburg Rsvr's energy balance leans toward cold weather: 6,065 annual heating degree days against 636 for cooling. Its 44.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Charlotteburg Rsvr's frost-free season lasts about 175 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 Charlotteburg Rsvr's middle-range seasonal profile. The measured spread is 44.9°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Charlotteburg Rsvr carries 52.2 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Charlotteburg Rsvr'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 Charlotteburg Rsvr, 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 Charlotteburg Rsvr's primary station: CHARLOTTEBURG RSVR (USC00281582). 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 Charlotteburg Rsvr; 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 Charlotteburg Rsvr comes from its primary NOAA station record.
