The year, day by day
Summer here tops out rather than builds: the warmest normal high is 79°F around July 27, short of 90°F on every date, while 152 dates carry a normal low at or below freezing, the coldest 14°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around November 11, 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.
Where the wet dates fall
The likeliest wet date is December 24, when 39% of years recorded at least a hundredth of an inch. The driest is September 2 at 24%. Summed across the calendar, that is about 123 wet dates a year.
The widest day
April 28 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Cape Neddick spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Cape Neddick has no dry season to plan around, though it does carry a wide 46.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 5.3" and August 3.6". 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 Cape Neddick, it arrives in quantity
51.6" of precipitation falls across only about 123 wet days here, averaging 0.42 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 123 a year, 34% of all days
- Average depth per wet day
- 0.42 inches
- Most wet days
- June, about 12
- Fewest wet days
- September, 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 Cape Neddick
Cape Neddick averages 70.1 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 26 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: 70.1 inches of depth.
- Days recording measurable snow: about 26 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 14% 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 Cape Neddick
heating led · wet · mid swing
Cape Neddick's energy balance leans toward cold weather: 6,967 annual heating degree days against 415 for cooling. Its 46.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Cape Neddick's frost-free season lasts about 166 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
