The year, day by day
Summer here tops out rather than builds: the warmest normal high is 76°F around July 22, short of 90°F on every date, while 197 dates carry a normal low at or below freezing, the coldest 13°F near February 5.
The freezing stretch
The normal low stays at or below 32°F into April 30, then returns to freezing around October 17, covering 197 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 18, when 54% of years recorded at least a hundredth of an inch. The driest is August 26 at 25%. Summed across the calendar, that is about 149 wet dates a year.
The widest day
August 24 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Sundance Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 197 nights a year, placing this among the most frost-prone tenth of ranked stations.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Sundance earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Sundance spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Sundance has no dry season to plan around, though it does carry a 41.6°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 3.9" and January 1.6". 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.
Rain reaches Sundance in small, frequent amounts
Sundance records about 149 days with measurable precipitation a year and 29.2" in total, which works out to roughly 0.20 inches on an average wet day. Precipitation on 41% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: May, about 17 of them.
- Fewest: August, about 8.
- Average depth per wet day: 0.20 inches.
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 Sundance's climate pattern fits together
heating led · moderate · mid swing
Sundance's energy balance leans toward cold weather: 8,839 annual heating degree days against 157 for cooling. Its 41.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 124 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 February mark the typical warm and cold ends of the calendar in Sundance's middle-range seasonal profile. The measured spread is 41.6°F. The annual average is 41°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Sundance's 29.2 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 Sundance'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 Sundance, not an official NOAA class or a year-ahead forecast.
