The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 10, short of 90°F on every date, while 133 dates carry a normal low at or below freezing, the coldest 13°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into March 25, then returns to freezing around November 14, covering 133 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 2, when 40% of years recorded at least a hundredth of an inch. The driest is September 16 at 26%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
September 25 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

LE Claire L&d spreads its precipitation across the year
Neither half of the year dominates here: June through August take 35% of the annual total and December through February 14%, with neither reaching the 35% that would mark a distinct wet season. LE Claire L&d has no dry season to plan around, though it does carry a wide 53.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 4.8" and January 1.5". The three wettest months together take 37% 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 LE Claire L&d's precipitation splits across the calendar
About 111 days a year record measurable precipitation here, carrying 37.1" between them, or roughly 0.33 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 LE Claire L&d's climate pattern fits together
heating led · moderate · mid swing
LE Claire L&d's energy balance leans toward cold weather: 6,229 annual heating degree days against 1,024 for cooling. Its 53.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
LE Claire L&d's frost-free season lasts about 192 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 LE Claire L&d's middle-range seasonal profile. The measured spread is 53.2°F. The annual average is 51°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
LE Claire L&d's 37.1 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 LE Claire L&d'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 LE Claire L&d, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from LE Claire L&d's primary station: LE CLAIRE L&D 14 (USC00134705). 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 LE Claire L&d; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for LE Claire L&d comes from its primary NOAA station record.
