The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 8, short of 90°F on every date, while 122 dates carry a normal low at or below freezing, the coldest 23°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into March 19, then returns to freezing around November 19, covering 122 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.
The widest day
April 18 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Petersburg spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Petersburg has no dry season to plan around, though it does carry a 42°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 4.5" and November 2.5". The three wettest months together take 33% 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.

Data-derived climate profile
How Petersburg's climate pattern fits together
heating led · moderate · mid swing
Petersburg's energy balance leans toward cold weather: 4,795 annual heating degree days against 1,060 for cooling. Its 42.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Petersburg's frost-free season lasts about 180 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's middle-range seasonal profile. The measured spread is 42.0°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Petersburg's 40.3 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 Petersburg'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, not an official NOAA class or a year-ahead forecast.
