The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 19, short of 90°F on every date, while 134 dates carry a normal low at or below freezing, the coldest 17°F near January 27.
The freezing stretch
The normal low stays at or below 32°F into April 5, then returns to freezing around November 24, covering 134 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 October 23, when 48% of years recorded at least a hundredth of an inch. The driest is July 10 at 33%. Summed across the calendar, that is about 149 wet dates a year.
The widest day
May 18 carries the biggest normal gap between afternoon and dawn, 17°F between the normal high and the normal low.

Port Hope spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 17%, with neither reaching the 35% that would mark a distinct wet season. Port Hope has no dry season to plan around, though it does carry a 44.9°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 3.4" and February 1.4". 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.
How Port Hope's precipitation splits across the calendar
About 148 days a year record measurable precipitation here, carrying 30.4" between them, or roughly 0.20 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.

Data-derived climate profile
How Port Hope's climate pattern fits together
heating led · moderate · mid swing
Port Hope's energy balance leans toward cold weather: 6,942 annual heating degree days against 446 for cooling. Its 44.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Port Hope's frost-free season lasts about 189 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 Port Hope's middle-range seasonal profile. The measured spread is 44.9°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Port Hope's 30.4 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 Port Hope'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 Port Hope, 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 Port Hope's primary station: PORT HOPE (USW00094898). 2 NOAA stations are mapped to the Port Hope area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 2665800). Match rule for Port Hope: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Port Hope comes from its primary NOAA station record.
