The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 15, short of 90°F on every date, while 173 dates carry a normal low at or below freezing, the coldest 2°F near January 18.
The freezing stretch
The normal low stays at or below 32°F into April 13, then returns to freezing around October 24, 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.
Where the wet dates fall
The likeliest wet date is June 12, when 37% of years recorded at least a hundredth of an inch. The driest is January 24 at 15%. Summed across the calendar, that is about 88 wet dates a year.
The widest day
September 22 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Madison Wwtp runs a summer-peaked wet season
42% of Madison Wwtp'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 3.8", on a wide 59.7°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, July, August, taking 42% of the annual total between them.
- Driest month: January at 0.5".
- Winter share: 7% 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 Madison Wwtp's precipitation splits across the calendar
About 88 days a year record measurable precipitation here, carrying 25.6" between them, or roughly 0.29 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.
Winter brings real snow to Madison Wwtp
Madison Wwtp averages 46.9 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 24 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: 46.9 inches of depth.
- Days recording measurable snow: about 24 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 18% 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 Madison Wwtp
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Madison Wwtp logs 8,281 heating degree days, more than twice its 608 cooling total, while the typical coldest-to-warmest-month gap reaches 59.7°F. The annual mean therefore compresses two materially different seasons.
Madison Wwtp's frost-free season lasts about 152 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

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 Madison Wwtp; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
