Coldest Ocean Water Temperature in Decades Recorded Off San Diego County

The ocean temperature off Del Mar fell to 52.25 degrees this week, the lowest reading in San Diego County waters since UC San Diego began using a buoy system in the 1970s to monitor large areas of the U.S. coastline.

UCSD’s Scripps Institution of Oceanography said near-record low readings also were recorded this week at many other stations, including off Imperial Beach and Leucadia, where the temperature was 53.5 degrees on Wednesday.
