The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 30, short of 90°F on every date, while 132 dates carry a normal low at or below freezing, the coldest 20°F near January 10.
The freezing stretch
The normal low stays at or below 32°F into March 21, then returns to freezing around November 11, covering 132 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 11 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Winona Stands Nationally
The normal water year runs well above the national norm at roughly 51 inches.
Winona earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Winona spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Winona has no dry season to plan around, though it does carry a 44.5°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 6.6" and January 3.0". 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 Winona's climate pattern fits together
heating led · wet · mid swing
Winona's energy balance leans toward cold weather: 5,029 annual heating degree days against 1,034 for cooling. Its 44.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Winona's frost-free season lasts about 179 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 Winona's middle-range seasonal profile. The measured spread is 44.5°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Winona carries 50.5 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Winona'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 Winona, not an official NOAA class or a year-ahead forecast.
