The year, day by day
Groveland works both ends of the calendar. Normal highs climb to 92°F by July 22 and hold at or above 90°F on 48 dates, then normal lows drop to freezing or below on 83 dates, bottoming at 30°F around December 17.
When the heat sits
Normal highs reach 90°F from July 7 through August 23, covering 48 dates. The broader mild season, normal highs of 70°F or more, runs May 6 to October 24.
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 February 20, then returns to freezing around November 30, covering 83 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 March 2, when 36% of years recorded at least a hundredth of an inch. The driest is July 24 at 1%. Summed across the calendar, that is about 66 wet dates a year.
The widest day
August 7 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Groveland Stands Nationally
Daily temperature swings run wider than most of the country, peaking near 36°F between the normal high and low.

Groveland'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 1%. 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 32.3°F seasonal spread.
- Wettest month
- January, 7.2"
- Driest month
- July, 0.0"
- 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 Groveland, it arrives in quantity
38.7" of precipitation falls across only about 66 wet days here, averaging 0.59 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 66 a year, 18% of all days
- Average depth per wet day

- March, about 11
- Fewest wet days
- July, about 0
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.
Snow reaches Groveland, but rarely amounts to much
The normals record 3.8 inches of snow a year here, most likely in March. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 2 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Groveland's climate pattern fits together
heating led · moderate · mid swing
Groveland's energy balance leans toward cold weather: 4,099 annual heating degree days against 802 for cooling. Its 32.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Groveland's frost-free season lasts about 194 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 Groveland's middle-range seasonal profile. The measured spread is 32.3°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Groveland's 38.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 3.8 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Groveland'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 Groveland, not an official NOAA class or a year-ahead forecast.
