Oxnard has a warm-summer Mediterranean climate.
Mild, rainy winters and hot, dry summers — here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:
Highs near 23°C in August. About 3 days a year above 32 °C.
Lows near 8°C in January.
About 328 mm of rain a year. Wettest in February.
More sun than cloud through the year.
What "warm-summer Mediterranean" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Oxnard's type — warm-summer mediterranean — sits in the broad family of mild, temperate climates.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as Oxnard
A warm-summer Mediterranean climate (Csb) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Has Oxnard's climate type changed?
A climate type is a coarse bucket. It can hold steady for years while the weather inside it shifts — or tip into the next bucket.
What this climate means for you
Cool-season vegetables, stone fruit, berries and hops excel. Wine grapes do well at the warmer end.
Late spring through early autumn is the pristine window — warm, dry, sunny. Winter is wet but never brutal.
Comfortable year-round — sunny, dry summers and mild, wet winters. Heating is modest; AC is rarely necessary.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Oxnard's measured 30-year climate normals (1991–2020) — the same official records behind Oxnard's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
