Summer Ocean Temps
Ocean water temperaturesare either peaking late this month -- or are likely to peak in August -- as a result of many weeks of summer sunshine and warm coastal air temperatures. While the water offshore seldom exceeds 70 degrees Fahrenheit, shallow-water temperatures of 70-80 degrees are not uncommon on gently shelving beaches late in the day. Wide, sandy beaches such as Coronado, south Mission Beach, and La Jolla Shores are now at their best for comfortable bathing.
