The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 10, short of 90°F on every date, while 145 dates carry a normal low at or below freezing, the coldest 17°F near January 29.
The freezing stretch
The normal low stays at or below 32°F into April 3, then returns to freezing around November 11, covering 145 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 15, when 45% of years recorded at least a hundredth of an inch. The driest is September 3 at 33%. Summed across the calendar, that is about 140 wet dates a year.
The widest day
April 30 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Mahanoy City spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Mahanoy City has no dry season to plan around, though it does carry a wide 45.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: September averages 5.2" and February 3.0". The three wettest months together take 29% 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 Mahanoy City, it arrives in quantity
53.6" of precipitation falls across only about 140 wet days here, averaging 0.38 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 140 a year, 38% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- May, about 14
- Fewest wet days
- November, about 10
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.
Winter brings real snow to Mahanoy City
Mahanoy City averages 48.0 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 22 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 48.0 inches of depth.
- Days recording measurable snow: about 22 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 9% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.
