The year, day by day
Lowell Three Rivers works both ends of the calendar. Normal highs climb to 95°F by July 27 and hold at or above 90°F on 43 dates, then normal lows drop to freezing or below on 106 dates, bottoming at 28°F around December 21.
When the heat sits
Normal highs reach 90°F from July 10 through August 21, covering 43 dates. The broader mild season, normal highs of 70°F or more, runs May 6 to October 1.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 7, then returns to freezing around November 23, covering 106 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 January 14, when 58% of years recorded at least a hundredth of an inch. The driest is July 26 at 12%. Summed across the calendar, that is about 156 wet dates a year.
The widest day
July 31 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Lowell Three Rivers spreads its precipitation across the year
Neither half of the year dominates here: June through August take 11% of the annual total and December through February 33%, with neither reaching the 35% that would mark a distinct wet season. Lowell Three Rivers has no dry season to plan around, though it does carry a 40.2°F seasonal spread.
The gap between the wettest and driest month still matters: November averages 5.0" and July 0.6". The three wettest months together take 37% 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 Lowell Three Rivers's precipitation splits across the calendar
About 156 days a year record measurable precipitation here, carrying 39.7" between them, or roughly 0.25 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 Lowell Three Rivers's climate pattern fits together
heating led · moderate · mid swing
Lowell Three Rivers's energy balance leans toward cold weather: 5,429 annual heating degree days against 652 for cooling. Its 40.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Lowell Three Rivers's frost-free season lasts about 192 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Lowell Three Rivers's middle-range seasonal profile. The measured spread is 40.2°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Lowell Three Rivers's 39.7 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 Lowell Three Rivers'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 Lowell Three Rivers, not an official NOAA class or a year-ahead forecast.

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 Lowell Three Rivers; 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 Lowell Three Rivers comes from its primary NOAA station record.
