The year, day by day
The calendar barely moves in Hawthorne: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 48°F near December 21 and 79°F near August 29.
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 48°F around December 21.
Where the wet dates fall
The likeliest wet date is February 18, when 24% of years recorded at least a hundredth of an inch. The driest is August 14 at 0%. Summed across the calendar, that is about 38 wet dates a year.
The widest day
January 14 carries the biggest normal gap between afternoon and dawn, 18°F between the normal high and the normal low.

Where Hawthorne Stands Nationally
Aridity defines the water calendar: about 12 inches in a normal year lands this among the driest tenth of ranked stations.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 18°F.
Hawthorne earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Hawthorne's wet season runs through the cold months
December, January and February carry 66% of the year's precipitation here, while June through August contribute 0%. 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 14.4°F seasonal spread.
- Wettest month
- February, 3.0"
- Driest month
- August, 0.0"
- Wettest three months
- February, January, December (66% 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 Hawthorne's precipitation splits across the calendar
About 38 days a year record measurable precipitation here, carrying 11.8" between them, or roughly 0.31 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.

What Hawthorne's climate means for you
Hawthorne runs 65°F a year - peaking in August, coldest in December.
- Both loads matter across the year, 1,091 heating and 925 cooling degree days, so shoulder-season efficiency pays here.

Data-derived climate profile
How Hawthorne's climate pattern fits together
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 11.8 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. The monthly distribution matters because the total alone does not reveal the timing.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 14.4°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 65°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Hawthorne combines a compact 14.4°F annual temperature range with meaningful demand on both sides of the thermostat: 1,091 heating and 925 cooling degree days. The balance matters more here than either annual total in isolation.
A frost-free growing-season length is not available for Hawthorne. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Hawthorne's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Hawthorne, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
The year in four calendar signals
- Warmest normal
- August
- The month averages 72°F (22°C), a middling summer peak by national standards rather than an extreme one.
- Coldest normal
- December
- The coldest month still averages 58°F (14°C), above freezing, so this calendar has no hard winter.
- Rainfall rhythm
- February to June
- February is typically wettest; June is driest.
- Mild-temperature window
- January through December
- Monthly means sit between 55°F and 75°F in this window.
