Annual Water Temperature Trend

Oxnard sits on California’s central coast where the Pacific Ocean and Santa Barbara Channel shape local sea conditions; water temperatures reflect seasonal cycles and coastal upwelling driven by the California Current. Typical winter temperatures along Oxnard’s shoreline range from about 12 to 15 °C, with spring modestly warming to roughly 13 to 17 °C as upwelling eases. Summer brings the warmest conditions, generally between 17 and 21 °C, though occasional cooler spells from persistent upwelling can keep waters in the mid to high teens. In autumn the ocean usually remains pleasant for many visitors, cooling slowly to about 15 to 19 °C before winter lows return. Local weather patterns such as morning marine layer and onshore breezes also influence the perceived chill of the water and air.
