The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 24, short of 90°F on every date, while 203 dates carry a normal low at or below freezing, the coldest 9°F near December 22.
The freezing stretch
The normal low stays at or below 32°F into April 30, then returns to freezing around October 11, covering 203 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 27, when 32% of years recorded at least a hundredth of an inch. The driest is November 27 at 13%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
August 28 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Dillinger Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 203 nights a year, placing this among the most frost-prone tenth of ranked stations.
A drier-than-most normal water year — around 16 inches, below what four out of five ranked stations collect.

Dillinger spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 10%, with neither reaching the 35% that would mark a distinct wet season. Dillinger has no dry season to plan around, though it does carry a wide 48.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 3.1" and January 0.4". The three wettest months together take 47% 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 Dillinger's precipitation splits across the calendar
About 70 days a year record measurable precipitation here, carrying 15.5" between them, or roughly 0.22 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 Dillinger
Dillinger averages 37.4 inches of snowfall a year, with March the snowiest month on the normals, spread across roughly 20 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: 37.4 inches of depth.
- Days recording measurable snow: about 20 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 24% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Dillinger
heating led · dry · mid swing
Dillinger's energy balance leans toward cold weather: 7,759 annual heating degree days against 487 for cooling. Its 48.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 115 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Dillinger's primary station: DILLINGER (USC00482580). For informational purposes only.
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 Dillinger; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
