The year, day by day
Quincy works both ends of the calendar. Normal highs climb to 90°F by July 23 and hold at or above 90°F on 12 dates, then normal lows drop to freezing or below on 183 dates, bottoming at 25°F around January 1.
When the heat sits
Normal highs reach 90°F from July 20 through July 31, covering 12 dates. The broader mild season, normal highs of 70°F or more, runs May 14 to October 14.
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 April 17, then returns to freezing around October 18, covering 183 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 February 29, when 41% of years recorded at least a hundredth of an inch. The driest is July 13 at 2%. Summed across the calendar, that is about 83 wet dates a year.
The widest day
August 29 carries the biggest normal gap between afternoon and dawn, 44°F between the normal high and the normal low.

Where Quincy Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 44°F, sharper than nine in ten ranked stations see.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 183 nights a year, more than most ranked stations.

Quincy's wet season runs through the cold months
December, January and February carry 54% of the year's precipitation here, while June through August contribute 2%. 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 34.1°F seasonal spread.
- Wettest month
- January, 7.7"
- Driest month
- July, 0.1"
- Wettest three months
- January, February, December (54% 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.
When it rains in Quincy, it arrives in quantity
41.7" of precipitation falls across only about 84 wet days here, averaging 0.50 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 84 a year, 23% of all days
- Average depth per wet day
- 0.50 inches
- Most wet days
- March, about 13
- Fewest wet days
- July, about 1
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 Quincy
Quincy averages 28.4 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 11 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: 28.4 inches of depth.
- Days recording measurable snow: about 11 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 7% 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 Quincy
heating led · moderate · mid swing
Quincy's energy balance leans toward cold weather: 5,728 annual heating degree days against 283 for cooling. Its 34.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 126 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.
