The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 28, short of 90°F on every date, while 123 dates carry a normal low at or below freezing, the coldest 22°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into March 15, then returns to freezing around November 14, covering 123 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 1, when 40% of years recorded at least a hundredth of an inch. The driest is August 28 at 24%. Summed across the calendar, that is about 119 wet dates a year.
The widest day
October 20 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Millerstown spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Millerstown has no dry season to plan around, though it does carry a 42.9°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.7" and August 3.3". The three wettest months together take 30% 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.
When it rains in Millerstown, it arrives in quantity
52.7" of precipitation falls across only about 119 wet days here, averaging 0.44 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 119 a year, 33% of all days
- Average depth per wet day
- 0.44 inches

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Millerstown's climate pattern fits together
heating led · wet · mid swing
Millerstown's energy balance leans toward cold weather: 4,792 annual heating degree days against 1,088 for cooling. Its 42.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Millerstown's frost-free season lasts about 180 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Millerstown's middle-range seasonal profile. The measured spread is 42.9°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Millerstown carries 52.7 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Millerstown'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 Millerstown, 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 Millerstown's primary station: MILLERSTOWN 4E (USC00155444). 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 Millerstown; 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 Millerstown comes from its primary NOAA station record.
