The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 14, short of 90°F on every date, while 152 dates carry a normal low at or below freezing, the coldest 9°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into April 3, then returns to freezing around November 4, covering 152 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 September 5, when 50% of years recorded at least a hundredth of an inch. The driest is January 3 at 25%. Summed across the calendar, that is about 134 wet dates a year.
The widest day
April 29 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Boscobel runs a summer-peaked wet season
38% of Boscobel'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 June at 5.2", on a wide 53.3°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: June, May, August, taking 40% of the annual total between them.
- Driest month: February at 1.0".
- Winter share: 10% 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 Boscobel's precipitation splits across the calendar
About 133 days a year record measurable precipitation here, carrying 33.9" between them, or roughly 0.25 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 Boscobel's climate pattern fits together
heating led · moderate · mid swing
Boscobel's energy balance leans toward cold weather: 6,877 annual heating degree days against 738 for cooling. Its 53.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Boscobel's frost-free season lasts about 157 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 Boscobel's middle-range seasonal profile. The measured spread is 53.3°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Boscobel's 33.9 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 Boscobel'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 Boscobel, not an official NOAA class or a year-ahead forecast.
