The year, day by day
Summer here tops out rather than builds: the warmest normal high is 77°F around July 23, short of 90°F on every date, while 151 dates carry a normal low at or below freezing, the coldest 11°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into April 11, then returns to freezing around November 13, covering 151 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 4, when 39% of years recorded at least a hundredth of an inch. The driest is September 2 at 28%. Summed across the calendar, that is about 124 wet dates a year.
The widest day
February 9 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Where W Rockport Stands Nationally
This is one of the wettest normals climates ranked: about 56 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 19°F.
W Rockport earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

W Rockport spreads its precipitation across the year
Neither half of the year dominates here: June through August take 20% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. W Rockport has no dry season to plan around, though it does carry a wide 47°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 6.1" and July 3.2". 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.
When it rains in W Rockport, it arrives in quantity
56.2" of precipitation falls across only about 124 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 124 a year, 34% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- December, about 12
- Fewest wet days
- February, about 9
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 W Rockport
W Rockport averages 68.7 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 21 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: 68.7 inches of depth.
- Days recording measurable snow: about 21 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 12% 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.

When cold and snow define W Rockport
heating led · wet · mid swing
W Rockport's energy balance leans toward cold weather: 7,396 annual heating degree days against 311 for cooling. Its 47.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
W Rockport's frost-free season lasts about 175 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 W Rockport; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
