The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 27, short of 90°F on every date, while 191 dates carry a normal low at or below freezing, the coldest 12°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 15, covering 191 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 December 18, when 34% of years recorded at least a hundredth of an inch. The driest is August 22 at 12%. Summed across the calendar, that is about 83 wet dates a year.
The widest day
August 13 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Saint Anthony Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 191 nights a year, more than most ranked stations.
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Saint Anthony earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Saint Anthony spreads its precipitation across the year
Neither half of the year dominates here: June through August take 21% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Saint Anthony has no dry season to plan around, though it does carry a wide 47.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.9" and August 0.6". The three wettest months together take 36% 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.
Saint Anthony is dry, and what does fall arrives gently
Only about 82 days a year record measurable precipitation here, 23% of the calendar, and they carry 14.8" between them. At roughly 0.18 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is December at about 11 wet days; the driest is August at about 4.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Saint Anthony's limited precipitation lands
heating led · dry · mid swing
Saint Anthony's energy balance leans toward cold weather: 8,167 annual heating degree days against 215 for cooling. Its 47.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 128 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 January mark the typical warm and cold ends of the calendar in Saint Anthony's middle-range seasonal profile. The measured spread is 47.2°F. The annual average is 43°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Saint Anthony's cold-season load does not imply a wet climate. Annual precipitation is 14.8 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Saint Anthony's primary station: SAINT ANTHONY (USC00108022). 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 Saint Anthony; 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 Saint Anthony comes from its primary NOAA station record.
