The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 13, short of 90°F on every date, while 152 dates carry a normal low at or below freezing, the coldest 13°F near January 28.
The freezing stretch
The normal low stays at or below 32°F into April 8, then returns to freezing around November 9, 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
May 7 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Average monthly rainfall
Milford GM Proving Ground spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Milford GM Proving Ground has no dry season to plan around, though it does carry a wide 48.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 3.7" and February 1.9". The three wettest months together take 32% 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 Milford GM Proving Ground's climate pattern fits together
heating led · moderate · mid swing
Milford GM Proving Ground's energy balance leans toward cold weather: 6,853 annual heating degree days against 572 for cooling. Its 48.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Milford GM Proving Ground's frost-free season lasts about 159 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 Milford GM Proving Ground's middle-range seasonal profile. The measured spread is 48.2°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Milford GM Proving Ground's 34.1 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 Milford GM Proving Ground'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 Milford GM Proving Ground, 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 Milford GM Proving Ground's primary station: MILFORD GM PROVING GROUND (USC00205452). 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 Milford GM Proving Ground; 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 Milford GM Proving Ground comes from its primary NOAA station record.
