The year, day by day
Summer here tops out rather than builds: the warmest normal high is 77°F around July 23, short of 90°F on every date, while 188 dates carry a normal low at or below freezing, the coldest 1°F near January 26.
The freezing stretch
The normal low stays at or below 32°F into April 27, then returns to freezing around October 23, covering 188 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 21, when 59% of years recorded at least a hundredth of an inch. The driest is August 31 at 41%. Summed across the calendar, that is about 178 wet dates a year.
The widest day
February 20 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Middle Dam Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 188 nights a year, more than most ranked stations.
Middle Dam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Middle Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Middle Dam has no dry season to plan around, though it does carry a wide 51.8°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 4.6" and February 2.3". The three wettest months together take 31% 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 Middle Dam's precipitation splits across the calendar
About 178 days a year record measurable precipitation here, carrying 40.8" between them, or roughly 0.23 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 Middle Dam's climate pattern fits together
heating led · moderate · mid swing
Middle Dam's energy balance leans toward cold weather: 9,111 annual heating degree days against 164 for cooling. Its 51.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 135 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 Middle Dam's middle-range seasonal profile. The measured spread is 51.8°F. The annual average is 40°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Middle Dam's 40.8 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 Middle Dam'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 Middle Dam, 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 Middle Dam's primary station: MIDDLE DAM (USC00175261). 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 Middle Dam; 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 Middle Dam comes from its primary NOAA station record.
