The year, day by day
The calendar barely moves in Avalon Catalina: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 49°F near December 13 and 80°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 49°F around December 13.
Where the wet dates fall
The likeliest wet date is February 26, when 29% of years recorded at least a hundredth of an inch. The driest is August 20 at 3%. Summed across the calendar, that is about 61 wet dates a year.
The widest day
July 22 carries the biggest normal gap between afternoon and dawn, 18°F between the normal high and the normal low.

Where Avalon Catalina Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 18°F.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Avalon Catalina earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Avalon Catalina's wet season runs through the cold months
December, January and February carry 63% of the year's precipitation here, while June through August contribute 2%. 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 15.9°F seasonal spread.
- Wettest month
- January, 3.0"
- Driest month
- August, 0.0"
- Wettest three months
- January, February, December (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 Avalon Catalina's precipitation splits across the calendar
About 62 days a year record measurable precipitation here, carrying 12.8" between them, or roughly 0.21 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 Avalon Catalina's limited precipitation lands
heating led · dry · low swing
Heating is the larger measured load in Avalon Catalina, at 2,213 degree days versus 836 for cooling. Unlike a strongly continental record, however, its 15.9°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
A frost-free growing-season length is not available for Avalon Catalina. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
The calendar stays thermally compact and dry. August and February mark the typical warm and cold ends of the calendar, only 15.9°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 61°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Avalon Catalina's cold-season load does not imply a wet climate. Annual precipitation is 12.8 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 Avalon Catalina's primary station: AVALON CATALINA AP (USW00023191). 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 Avalon Catalina; 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 Avalon Catalina comes from its primary NOAA station record.
