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 197 dates carry a normal low at or below freezing, the coldest 10°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 26, then returns to freezing around October 13, 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.
The widest day
August 16 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Small 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.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Small earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Small 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 24%, with neither reaching the 35% that would mark a distinct wet season. Small has no dry season to plan around, though it does carry a wide 47.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.8" and August 0.8". 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.

Scarce-water calendar
Where Small's limited precipitation lands
heating led · dry · mid swing
Small's energy balance leans toward cold weather: 8,387 annual heating degree days against 208 for cooling. Its 47.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 107 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 Small's middle-range seasonal profile. The measured spread is 47.4°F. The annual average is 43°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Small's cold-season load does not imply a wet climate. Annual precipitation is 12.5 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.

August is typically driest; arid stations are defined by when water is absent, not by a four-season grid.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Small's primary station: SMALL 6N (USC00108500). 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 Small; 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 Small comes from its primary NOAA station record.
