The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 17, short of 90°F on every date, while 127 dates carry a normal low at or below freezing, the coldest 17°F near January 15.
The freezing stretch
The normal low stays at or below 32°F into March 17, then returns to freezing around November 12, covering 127 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 8, when 40% of years recorded at least a hundredth of an inch. The driest is January 6 at 16%. Summed across the calendar, that is about 100 wet dates a year.
The widest day
September 26 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

St Joseph Rosecrans runs a summer-peaked wet season
38% of St Joseph Rosecrans'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 May at 4.9", on a wide 50.4°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: May, June, July, taking 41% of the annual total between them.
- Driest month: January at 0.7".
- Winter share: 8% 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.
When it rains in St Joseph Rosecrans, it arrives in quantity
34.8" of precipitation falls across only about 99 wet days here, averaging 0.35 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 99 a year, 27% of all days
- Average depth per wet day
- 0.35 inches
- Most wet days
- May, about 12
- Fewest wet days
- January, about 5
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 St Joseph Rosecrans's climate pattern fits together
heating led · moderate · mid swing
St Joseph Rosecrans's energy balance leans toward cold weather: 5,385 annual heating degree days against 1,288 for cooling. Its 50.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
St Joseph Rosecrans's frost-free season lasts about 181 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 St Joseph Rosecrans's middle-range seasonal profile. The measured spread is 50.4°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
St Joseph Rosecrans's 34.8 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 St Joseph Rosecrans'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 St Joseph Rosecrans, 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 St Joseph Rosecrans's primary station: ST JOSEPH ROSECRANS AP (USW00013993). 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 St Joseph Rosecrans; 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 St Joseph Rosecrans comes from its primary NOAA station record.
