The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 13, short of 90°F on every date, while 148 dates carry a normal low at or below freezing, the coldest 15°F near January 26.
The freezing stretch
The normal low stays at or below 32°F into April 6, then returns to freezing around November 11, covering 148 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 March 21, when 35% of years recorded at least a hundredth of an inch. The driest is July 13 at 27%. Summed across the calendar, that is about 113 wet dates a year.
The widest day
October 6 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

West Medway 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 24%, with neither reaching the 35% that would mark a distinct wet season. West Medway 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: October averages 5.1" and February 3.3". 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 West Medway, it arrives in quantity
50.4" of precipitation falls across only about 113 wet days here, averaging 0.45 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 113 a year, 31% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- March, about 11
- Fewest wet days
- February, about 8
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 West Medway
West Medway averages 51.5 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 19 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: 51.5 inches of depth.
- Days recording measurable snow: about 19 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 10% 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.

Snow and freeze rhythm
When cold and snow define West Medway
heating led · wet · mid swing
West Medway's energy balance leans toward cold weather: 6,066 annual heating degree days against 665 for cooling. Its 45.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
West Medway's frost-free season lasts about 162 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

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 West Medway; 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 West Medway comes from its primary NOAA station record.
