Ocean Water Temperatures Rising
Ocean temps are rising into the 60s this month, perhaps to reach the 70s in July or August. The early-summer cool weather along San Diego's coastline, disappointing to many tourists, is mostly caused by the sluggish warming of the ocean water. The payoff will come later: as the ocean gives up heat absorbed during the sunny summer months, we'll enjoy warm days and evenings well into autumn.
