Climate Insight: Oxnard Ventura CO, CA

The NOAA 1991–2020 climate normals describe Oxnard Ventura CO, California as a location with an annual average temperature of 61°F, ranging from a mean daily high of 69°F to a mean daily low of 53°F. August is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00093110, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Oxnard Ventura CO receives roughly 12.9 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near N/A and the first fall freeze near N/A. For energy use, 1,692 heating degree days and 324 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Oxnard Ventura CO scores 77/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for August-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
