La Jolla Shores Professional Review and Guide
"For beachcombing, tidepool exploration, and all-over suntanning, La Jolla Shores Beach and the coastal stretch north of it can’t be beat. It’s important to note, though, that some of the better attributes of this environment aren’t available at higher tides—typically 3 feet or more.
In fact, the highest tides of up to 7 feet will limit your walk along the beach to only 0.5 mile each way, assuming you don’t want to be swamped by waves. Extreme low tides (expressed on tide tables as 0 feet to –2 feet), on the other hand, are perfect for viewing marine life amid the rocky outcrops that lie at the lowest levels of the intertidal zone."
