The year, day by day
The calendar barely moves in Lompoc: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 42°F near December 17 and 75°F near September 15.
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 17.
Where the wet dates fall
The likeliest wet date is February 18, when 30% of years recorded at least a hundredth of an inch. The driest is August 9 at 1%. Summed across the calendar, that is about 48 wet dates a year.
The widest day
November 2 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Lompoc Stands Nationally
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Lompoc earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Lompoc'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 12.1°F seasonal spread.

- February, 3.7"

- August, 0.0"

- February, January, March (63% 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 Lompoc's precipitation splits across the calendar
About 47 days a year record measurable precipitation here, carrying 15.4" between them, or roughly 0.33 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.
Lompoc'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 Lompoc's climate pattern fits together
heating led · dry · low swing
Heating is the larger measured load in Lompoc, at 2,248 degree days versus 168 for cooling. Unlike a strongly continental record, however, its 12.1°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Lompoc has a long frost-free window of roughly 333 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. September and December mark the typical warm and cold ends of the calendar, only 12.1°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 59°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Lompoc's cold-season load does not imply a wet climate. Annual precipitation is 15.4 inches, which places the station in PlainClimate's dry range. Recorded annual snowfall is negligible. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Lompoc'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 Lompoc, not an official NOAA class or a year-ahead forecast.
