The year, day by day
The calendar barely moves in Morro Bay Fire Dept: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 46°F near December 25 and 73°F near October 10.
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 46°F around December 25.
Where the wet dates fall
The likeliest wet date is February 17, when 29% of years recorded at least a hundredth of an inch. The driest is July 26 at 1%. Summed across the calendar, that is about 43 wet dates a year.
The widest day
November 6 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Morro Bay Fire Dept'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 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 8.3°F seasonal spread.

- January, 3.6"
- Driest month
- August, 0.0"
- Wettest three months
- January, February, March (61% 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 Morro Bay Fire Dept, it arrives in quantity
17.0" of precipitation falls across only about 42 wet days here, averaging 0.40 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 42 a year, 12% of all days
- Average depth per wet day
- 0.40 inches

- August, about 0
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.
Snow reaches Morro Bay Fire Dept, but rarely amounts to much
The normals record 0.1 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Morro Bay Fire Dept's climate pattern fits together
heating led · dry · low swing
Heating is the larger measured load in Morro Bay Fire Dept, at 2,194 degree days versus 208 for cooling. Unlike a strongly continental record, however, its 8.3°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 Morro Bay Fire Dept. 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. September and December mark the typical warm and cold ends of the calendar, only 8.3°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.
Morro Bay Fire Dept's cold-season load does not imply a wet climate. Annual precipitation is 17.0 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 Morro Bay Fire Dept'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 Morro Bay Fire Dept, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Morro Bay Fire Dept's primary station: MORRO BAY FIRE DEPT (USC00045866). 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 Morro Bay Fire Dept; 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 Morro Bay Fire Dept comes from its primary NOAA station record.
