The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 31, short of 90°F on every date, while 152 dates carry a normal low at or below freezing, the coldest 22°F near December 21.
The freezing stretch
The normal low stays at or below 32°F into April 2, then returns to freezing around November 3, covering 152 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 9 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Plummer Stands Nationally
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.
Plummer earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Plummer spreads its precipitation across the year
Neither half of the year dominates here: June through August take 12% of the annual total and December through February 34%, with neither reaching the 35% that would mark a distinct wet season. Plummer has no dry season to plan around, though it does carry a 38°F seasonal spread.
The gap between the wettest and driest month still matters: January averages 3.8" and July 0.7". The three wettest months together take 38% 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.

Data-derived climate profile
How Plummer's climate pattern fits together
heating led · moderate · mid swing
Plummer's energy balance leans toward cold weather: 7,000 annual heating degree days against 278 for cooling. Its 38.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 147 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.
August and December mark the typical warm and cold ends of the calendar in Plummer's middle-range seasonal profile. The measured spread is 38.0°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Plummer's 28.5 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 Plummer'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 Plummer, not an official NOAA class or a year-ahead forecast.
