Rainfall
Variable Rainfall in a Mediterranean Climate
With a Mediterranean climate, temperatures within the Water Authority’s service area are traditionally mild year-round. Additionally, average annual rainfall totals roughly 10 inches on the coast and more than 33 inches in the inland mountains. Rainfall follows a seasonal distribution pattern, with much of the region’s precipitation occurring between December and March.
Note: The table below displays annual rainfall by location and Water Year. You can filter the table to show just one location at a time and/or only specific years. You can also sort data within each location by Water Year, actual rainfall, normal rainfall or the percentage of normal. Normal rainfall is adjusted periodically to reflect recent historic years. Water years begin October 1 and end September 30.
