The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 9, short of 90°F on every date, while 110 dates carry a normal low at or below freezing, the coldest 22°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into March 18, then returns to freezing around November 30, covering 110 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 11, when 46% of years recorded at least a hundredth of an inch. The driest is January 28 at 31%. Summed across the calendar, that is about 137 wet dates a year.
The widest day
April 20 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Catoctin Mtn Park spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Catoctin Mtn Park has no dry season to plan around, though it does carry a 43.1°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 5.3" and February 3.0". 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 Catoctin Mtn Park, it arrives in quantity
48.6" of precipitation falls across only about 136 wet days here, averaging 0.36 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 136 a year, 37% of all days
- Average depth per wet day
- 0.36 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 Catoctin Mtn Park's climate pattern fits together
heating led · wet · mid swing
Catoctin Mtn Park's energy balance leans toward cold weather: 5,088 annual heating degree days against 898 for cooling. Its 43.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Catoctin Mtn Park's frost-free season lasts about 199 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 Catoctin Mtn Park's middle-range seasonal profile. The measured spread is 43.1°F. The annual average is 53°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Catoctin Mtn Park carries 48.6 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 Catoctin Mtn Park'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 Catoctin Mtn Park, 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 Catoctin Mtn Park's primary station: CATOCTIN MTN PARK (USC00181530). 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 Catoctin Mtn Park; 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 Catoctin Mtn Park comes from its primary NOAA station record.
