The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 12, short of 90°F on every date, while 173 dates carry a normal low at or below freezing, the coldest 3°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 16, then returns to freezing around October 27, covering 173 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
May 8 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
River Falls runs a summer-peaked wet season
41% of River Falls'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 5.0", on a wide 56.7°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, August, July, taking 41% of the annual total between them.
- Driest month: February at 0.8".
- 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.

Data-derived climate profile
How River Falls's climate pattern fits together
heating led · moderate · high swing
Winter and seasonal range jointly define this record. River Falls logs 8,281 heating degree days, more than twice its 459 cooling total, while the typical coldest-to-warmest-month gap reaches 56.7°F. The annual mean therefore compresses two materially different seasons.
Only about 143 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
River Falls's calendar has a pronounced split: July and January mark the typical warm and cold ends of the calendar, with 56.7°F between them. The annual average is 43°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
River Falls's 34.1 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 River Falls'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 River Falls, not an official NOAA class or a year-ahead forecast.
