The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 26, short of 90°F on every date, while 196 dates carry a normal low at or below freezing, the coldest 15°F near December 19.
The freezing stretch
The normal low stays at or below 32°F into April 28, then returns to freezing around October 16, covering 196 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 April 17, when 24% of years recorded at least a hundredth of an inch. The driest is July 9 at 9%. Summed across the calendar, that is about 60 wet dates a year.
The widest day
August 19 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Arthur Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 196 nights a year, more than most ranked stations.
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.
Arthur earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Arthur spreads its precipitation across the year
Neither half of the year dominates here: June through August take 14% of the annual total and December through February 34%, with neither reaching the 35% that would mark a distinct wet season. Arthur has no dry season to plan around, though it does carry a 41.9°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 1.8" and July 0.5". The three wettest months together take 35% 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 Arthur's precipitation splits across the calendar
About 59 days a year record measurable precipitation here, carrying 14.0" between them, or roughly 0.24 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.

Scarce-water calendar
Where Arthur's limited precipitation lands
heating led · dry · mid swing
Arthur's energy balance leans toward cold weather: 7,522 annual heating degree days against 197 for cooling. Its 41.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 106 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 Arthur's middle-range seasonal profile. The measured spread is 41.9°F. The annual average is 45°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Arthur's cold-season load does not imply a wet climate. Annual precipitation is 14.1 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 Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Arthur's primary station: ARTHUR 4NW (USC00260438). 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 Arthur; 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 Arthur comes from its primary NOAA station record.
