The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 25, short of 90°F on every date, while 171 dates carry a normal low at or below freezing, the coldest 24°F near December 19.
The freezing stretch
The normal low stays at or below 32°F into April 26, then returns to freezing around November 8, covering 171 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 16, when 25% of years recorded at least a hundredth of an inch. The driest is July 13 at 4%. Summed across the calendar, that is about 51 wet dates a year.
The widest day
June 26 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Glenbrook's wet season runs through the cold months
December, January and February carry 48% of the year's precipitation here, while June through August contribute 6%. 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 30.5°F seasonal spread.
- Wettest month
- January, 3.2"
- Driest month
- August, 0.2"
- Wettest three months
- January, December, February (48% 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 Glenbrook, it arrives in quantity
18.5" of precipitation falls across only about 51 wet days here, averaging 0.36 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 51 a year, 14% of all days
- Average depth per wet day

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.

Data-derived climate profile
How Glenbrook's climate pattern fits together
heating led · dry · mid swing
Glenbrook's energy balance leans toward cold weather: 6,969 annual heating degree days against 66 for cooling. Its 30.5°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.
August and January mark the typical warm and cold ends of the calendar in Glenbrook's middle-range seasonal profile. The measured spread is 30.5°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Glenbrook's cold-season load does not imply a wet climate. Annual precipitation is 18.5 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Glenbrook'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 Glenbrook, not an official NOAA class or a year-ahead forecast.
