The year, day by day
The calendar barely moves in Kentfield: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 41°F near December 24 and 83°F near August 24.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 41°F around December 24.
Where the wet dates fall
The likeliest wet date is February 17, when 39% of years recorded at least a hundredth of an inch. The driest is July 28 at 1%. Summed across the calendar, that is about 68 wet dates a year.
The widest day
August 30 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Kentfield's wet season runs through the cold months
December, January and February carry 61% 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 an unusually narrow 19.2°F seasonal spread.
- Wettest month
- December, 9.8"
- Driest month
- July, 0.0"
- Wettest three months
- December, January, February (61% 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 Kentfield, it arrives in quantity
44.4" of precipitation falls across only about 68 wet days here, averaging 0.65 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 68 a year, 19% of all days
- Average depth per wet day
- 0.65 inches
- Most wet days
- December, about 12
- 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.
Kentfield's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Kentfield's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Kentfield, at 2,546 degree days versus 458 for cooling. Unlike a strongly continental record, however, its 19.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
The frost-free window extends for about 336 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Temperature varies within a narrow 19.2°F band across the normal year. August and December mark the typical warm and cold ends of the calendar. The annual average is 59°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Kentfield's 44.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Kentfield'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 Kentfield, not an official NOAA class or a year-ahead forecast.
