10 day forecast fairfield ca

As of 31 October 2026, the ten-day meteorological forecast for Fairfield, California, indicates a period of stable, mild autumn weather transitioning into slightly cooler temperatures. Residents can expect clear skies and abundant sunshine throughout the first week of November, with daytime high temperatures consistently hovering in the low to mid-70s Fahrenheit. These pleasant conditions are driven by a high-pressure ridge currently dominating Northern California, which is effectively suppressing any significant precipitation or storm systems. Beginning around 5 November 2026, long-range models suggest a gradual shift as a weak trough approaches the Pacific Coast. This transition is expected to bring an increase in cloud cover and a modest drop in daytime highs, likely settling into the upper 60s by the end of the ten-day period. Overnight lows will remain crisp, generally ranging between 45 and 50 degrees Fahrenheit. While no major rain events are forecasted for the immediate ten-day window, the cooling trend signals the typical seasonal progression toward late autumn, providing Fairfield with dry and comfortable conditions for outdoor activities through the first week of November.
