The year, day by day
Summer here tops out rather than builds: the warmest normal high is 75°F around July 24, short of 90°F on every date, while 140 dates carry a normal low at or below freezing, the coldest 17°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into April 9, then returns to freezing around November 22, covering 140 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 18, when 42% of years recorded at least a hundredth of an inch. The driest is August 26 at 30%. Summed across the calendar, that is about 136 wet dates a year.
The widest day
June 14 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Tenants Harbor spreads its precipitation across the year
Neither half of the year dominates here: June through August take 21% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Tenants Harbor has no dry season to plan around, though it does carry a 39°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 4.8" and August 2.9". 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.
How Tenants Harbor's precipitation splits across the calendar
About 136 days a year record measurable precipitation here, carrying 47.6" between them, or roughly 0.35 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Tenants Harbor
Tenants Harbor averages 53.1 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 20 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: 53.1 inches of depth.
- Days recording measurable snow: about 20 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 11% 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 Tenants Harbor
heating led · wet · mid swing
Tenants Harbor's energy balance leans toward cold weather: 6,877 annual heating degree days against 122 for cooling. Its 39.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Tenants Harbor's frost-free season lasts about 181 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Tenants Harbor's primary station: TENANTS HARBOR (USC00176881). 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 Tenants Harbor; 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 Tenants Harbor comes from its primary NOAA station record.
