The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 8, short of 90°F on every date, while 139 dates carry a normal low at or below freezing, the coldest 16°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into April 1, then returns to freezing around November 15, covering 139 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 January 8, when 53% of years recorded at least a hundredth of an inch. The driest is August 30 at 32%. Summed across the calendar, that is about 148 wet dates a year.
The widest day
April 22 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

South Bend Michiana Rgnl spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. South Bend Michiana Rgnl has no dry season to plan around, though it does carry a wide 48.3°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 4.2" and February 2.3". The three wettest months together take 31% 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.
How South Bend Michiana Rgnl's precipitation splits across the calendar
About 148 days a year record measurable precipitation here, carrying 39.2" between them, or roughly 0.27 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 South Bend Michiana Rgnl
South Bend Michiana Rgnl averages 64.5 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 42 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: 64.5 inches of depth.
- Days recording measurable snow: about 42 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 16% 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.

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 South Bend Michiana Rgnl; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
