The year, day by day
The calendar barely moves in Moffett Federal Airfield: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 42°F near December 20 and 78°F near September 4.
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 42°F around December 20.
Where the wet dates fall
The likeliest wet date is February 17, when 40% 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
October 13 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Moffett Federal Airfield Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 21°F.
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.
Moffett Federal Airfield earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Moffett Federal Airfield's wet season runs through the cold months
December, January and February carry 59% 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 17.5°F seasonal spread.
- Wettest month
- February, 2.9"
- Driest month
- July, 0.0"
- Wettest three months
- February, December, January (59% 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.
How Moffett Federal Airfield's precipitation splits across the calendar
About 66 days a year record measurable precipitation here, carrying 13.4" between them, or roughly 0.20 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Scarce-water calendar
Where Moffett Federal Airfield's limited precipitation lands
heating led · dry · low swing
Heating is the larger measured load in Moffett Federal Airfield, at 2,264 degree days versus 427 for cooling. Unlike a strongly continental record, however, its 17.5°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Moffett Federal Airfield has a long frost-free window of roughly 351 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 17.5°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 60°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Moffett Federal Airfield's cold-season load does not imply a wet climate. Annual precipitation is 13.4 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Moffett Federal Airfield's primary station: MOFFETT FEDERAL AIRFIELD (USW00023244). 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 Moffett Federal Airfield; 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 Moffett Federal Airfield comes from its primary NOAA station record.
