The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 16, short of 90°F on every date, while 143 dates carry a normal low at or below freezing, the coldest 16°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into April 4, then returns to freezing around November 14, covering 143 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 May 15, when 40% of years recorded at least a hundredth of an inch. The driest is August 29 at 27%. Summed across the calendar, that is about 130 wet dates a year.
The widest day
May 1 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Groveland spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Groveland has no dry season to plan around, though it does carry a wide 46°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: March averages 5.0" and August 3.4". The three wettest months together take 30% 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.
When it rains in Groveland, it arrives in quantity
49.0" of precipitation falls across only about 130 wet days here, averaging 0.38 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 130 a year, 36% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- May, about 13
- Fewest wet days
- September, about 9
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 Groveland
Groveland averages 67.1 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 29 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: 67.1 inches of depth.
- Days recording measurable snow: about 29 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 14% 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 Groveland
heating led · wet · mid swing
Groveland's energy balance leans toward cold weather: 6,323 annual heating degree days against 621 for cooling. Its 46.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Groveland's frost-free season lasts about 158 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-
1. Groveland coldest normal
January
The monthly mean of 26°F (-3°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Groveland typical freeze period
January through December
The station reports average freezing days from January through December.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Groveland's primary station: GROVELAND (USC00193276). For informational purposes only.
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 Groveland; 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 Groveland comes from its primary NOAA station record.
