The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 20, short of 90°F on every date, while 168 dates carry a normal low at or below freezing, the coldest 4°F near January 16.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around October 26, covering 168 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 24, when 35% of years recorded at least a hundredth of an inch. The driest is November 15 at 16%. Summed across the calendar, that is about 85 wet dates a year.
The widest day
September 28 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Redwood Falls runs a summer-peaked wet season
42% of Redwood 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 58.4°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: June, August, May, taking 43% 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 Redwood Falls, it arrives in quantity
30.9" of precipitation falls across only about 84 wet days here, averaging 0.37 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 84 a year, 23% of all days
- Average depth per wet day
- 0.37 inches
- Most wet days
- May, about 11
- Fewest wet days
- November, 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.
Winter brings real snow to Redwood Falls
Redwood Falls averages 43.6 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 19 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 43.6 inches of depth.
- Days recording measurable snow: about 19 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 14% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Redwood Falls
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Redwood Falls logs 7,960 heating degree days, more than twice its 626 cooling total, while the typical coldest-to-warmest-month gap reaches 58.4°F. The annual mean therefore compresses two materially different seasons.
Redwood Falls's frost-free season lasts about 163 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
