SAN DIEGO — Lifeguards at county beaches from Ocean Beach to La Jolla were kept very busy this weekend, officials said Sunday. Sunny skies brought thousands of people out to San Diego beaches and with large crowds came a large number of rescues.

On Saturday, there were an estimated 125,000 beachgoers along the San Diego coast, according to Lt. Andy Lerum of Lifeguard Services.

Some were having a final summer beach day as many local students will head back to school this week. 

Lifeguards performed 40 water rescues and provided medical aid to 88 people.

Preventive acts -- which include separating surfers and swimmers, keeping swimmers away from riptide areas and issuing alcohol citations -- numbered 1,942, officials said.
