The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 12, short of 90°F on every date, while 121 dates carry a normal low at or below freezing, the coldest 21°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into March 21, then returns to freezing around November 22, covering 121 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 June 3, when 44% of years recorded at least a hundredth of an inch. The driest is November 8 at 31%. Summed across the calendar, that is about 138 wet dates a year.
The widest day
April 25 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Pottstown Limerick 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 21%, with neither reaching the 35% that would mark a distinct wet season. Pottstown Limerick has no dry season to plan around, though it does carry a 44.3°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 4.8" and February 2.6". 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 Pottstown Limerick's precipitation splits across the calendar
About 137 days a year record measurable precipitation here, carrying 45.3" between them, or roughly 0.33 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 Pottstown Limerick's climate pattern fits together
heating led · wet · mid swing
Pottstown Limerick's energy balance leans toward cold weather: 5,534 annual heating degree days against 794 for cooling. Its 44.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Pottstown Limerick's frost-free season lasts about 186 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 Pottstown Limerick's middle-range seasonal profile. The measured spread is 44.3°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Pottstown Limerick carries 45.3 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 Pottstown Limerick'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 Pottstown Limerick, 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 Pottstown Limerick's primary station: POTTSTOWN LIMERICK AP (USW00054782). 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 Pottstown Limerick; 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 Pottstown Limerick comes from its primary NOAA station record.
