Tourmaline Surf Park is somewhat of a hidden gem located in North Pacific Beach. It's a surfing beach (including kite surfing and sailboarding) but also family-friendly just a tad bit south. There are less tourists probably because there aren't too many hotels within walking distance, but restaurants and grocery stores (perfect for those who want to picnic) of Pacific Beach to the south and La Jolla to the north are nearby. There's a parking lot with showers and restrooms as well as lifeguards on duty. Beware that you will have to climb down a few rocks to hit the sand.
