Data-derived climate profile
How Oxnard's climate pattern fits together
heating led · low swing
Heating is the larger measured load in Oxnard, at 1,605 degree days versus 348 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.
A frost-free growing-season length is not available for Oxnard. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
Temperature varies within a narrow 12.1°F band across the normal year. August and January mark the typical warm and cold ends of the calendar. The annual average is 62°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A moisture-range label is withheld because Oxnard's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Oxnard'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 Oxnard, 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 Oxnard's primary station: OXNARD (USC00046569). 2 NOAA stations are mapped to the Oxnard area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 0654652). Match rule for Oxnard: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Oxnard comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
