The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 13, short of 90°F on every date, while 155 dates carry a normal low at or below freezing, the coldest 7°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into April 6, then returns to freezing around November 4, covering 155 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 8, when 42% of years recorded at least a hundredth of an inch. The driest is February 17 at 21%. Summed across the calendar, that is about 107 wet dates a year.
The widest day
May 15 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Lower St Anthony Falls runs a summer-peaked wet season
40% of Lower St Anthony Falls'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 4.8", on a wide 58.7°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 40% of the annual total between them.
- Driest month: February at 0.9".
- Winter share: 9% 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 Lower St Anthony Falls's precipitation splits across the calendar
About 107 days a year record measurable precipitation here, carrying 34.4" between them, or roughly 0.32 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 Lower St Anthony Falls's climate pattern fits together
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Lower St Anthony Falls logs 7,699 heating degree days, more than twice its 734 cooling total, while the typical coldest-to-warmest-month gap reaches 58.7°F. The annual mean therefore compresses two materially different seasons.
Lower St Anthony Falls's frost-free season lasts about 176 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Lower St Anthony Falls's calendar has a pronounced split: July and January mark the typical warm and cold ends of the calendar, with 58.7°F between them. The annual average is 46°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
Lower St Anthony Falls's 34.4 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 Lower St Anthony Falls'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 Lower St Anthony Falls, 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 Lower St Anthony Falls's primary station: LOWER ST ANTHONY FALLS (USC00214884). 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 Lower St Anthony Falls; 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 Lower St Anthony Falls comes from its primary NOAA station record.
