The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 4, short of 90°F on every date, while 118 dates carry a normal low at or below freezing, the coldest 21°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into March 17, then returns to freezing around November 21, covering 118 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 April 25, when 36% of years recorded at least a hundredth of an inch. The driest is August 28 at 20%. Summed across the calendar, that is about 103 wet dates a year.
The widest day
April 12 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Petersburg 61 Brg 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 21%, with neither reaching the 35% that would mark a distinct wet season. Petersburg 61 Brg has no dry season to plan around, though it does carry a 44.6°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 5.1" and February 2.9". The three wettest months together take 31% 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 Petersburg 61 Brg, it arrives in quantity
47.9" of precipitation falls across only about 103 wet days here, averaging 0.46 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 103 a year, 28% of all days
- Average depth per wet day
- 0.46 inches

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 Petersburg 61 Brg's climate pattern fits together
heating led · wet · mid swing
Petersburg 61 Brg's energy balance leans toward cold weather: 5,064 annual heating degree days against 1,033 for cooling. Its 44.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Petersburg 61 Brg's frost-free season lasts about 185 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 Petersburg 61 Brg's middle-range seasonal profile. The measured spread is 44.6°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Petersburg 61 Brg carries 47.9 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 Petersburg 61 Brg'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 Petersburg 61 Brg, 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 Petersburg 61 Brg's primary station: PETERSBURG 61 BRG (USC00126872). 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 Petersburg 61 Brg; 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 Petersburg 61 Brg comes from its primary NOAA station record.
