The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 28, short of 90°F on every date, while 183 dates carry a normal low at or below freezing, the coldest 23°F near December 21.
The freezing stretch
The normal low stays at or below 32°F into April 15, then returns to freezing around October 16, covering 183 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 November 25, when 47% of years recorded at least a hundredth of an inch. The driest is August 11 at 11%. Summed across the calendar, that is about 120 wet dates a year.
The widest day
August 4 carries the biggest normal gap between afternoon and dawn, 42°F between the normal high and the normal low.

Where Elgin Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 42°F, sharper than nine in ten ranked stations see.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 183 nights a year, more than most ranked stations.
Elgin earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Elgin's wet season runs through the cold months
December, January and February carry 36% of the year's precipitation here, while June through August contribute 12%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 35.7°F seasonal spread.
- Wettest month
- December, 3.8"
- Driest month
- August, 0.7"
- Wettest three months
- December, January, November (39% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Elgin's precipitation splits across the calendar
About 120 days a year record measurable precipitation here, carrying 25.9" 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.

Data-derived climate profile
How Elgin's climate pattern fits together
heating led · moderate · mid swing
Elgin's energy balance leans toward cold weather: 6,400 annual heating degree days against 258 for cooling. Its 35.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 117 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.
July and December mark the typical warm and cold ends of the calendar in Elgin's middle-range seasonal profile. The measured spread is 35.7°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Elgin's 25.9 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Elgin'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 Elgin, not an official NOAA class or a year-ahead forecast.
