The year, day by day
Cambridge works both ends of the calendar. Normal highs climb to 95°F by July 28 and hold at or above 90°F on 46 dates, then normal lows drop to freezing or below on 156 dates, bottoming at 17°F around January 6.
When the heat sits
Normal highs reach 90°F from July 8 through August 22, covering 46 dates. The broader mild season, normal highs of 70°F or more, runs May 9 to October 4.
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 26, then returns to freezing around October 23, covering 156 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 5, when 38% of years recorded at least a hundredth of an inch. The driest is August 6 at 7%. Summed across the calendar, that is about 89 wet dates a year.
The widest day
August 21 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Cambridge Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 38°F, sharper than nine in ten ranked stations see.

Cambridge's wet season runs through the cold months
December, January and February carry 44% of the year's precipitation here, while June through August contribute 9%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a wide 50.9°F gap between its warmest and coldest month.
- Wettest month
- December, 3.9"
- Driest month
- August, 0.3"
- Wettest three months
- December, January, February (44% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Cambridge's precipitation splits across the calendar
About 89 days a year record measurable precipitation here, carrying 21.4" between them, or roughly 0.24 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 Cambridge's climate pattern fits together
heating led · moderate · mid swing
Cambridge's energy balance leans toward cold weather: 6,734 annual heating degree days against 693 for cooling. Its 50.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 135 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Cambridge's middle-range seasonal profile. The measured spread is 50.9°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Cambridge's 21.4 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 Cambridge'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 Cambridge, not an official NOAA class or a year-ahead forecast.
