A coastal city’s tidal schedule provides predicted times and heights of high and low tides. For a location like Laguna Beach, with its coves, beaches, and marine life, this information is presented in a readily accessible format, often online or in print. A typical example would show daily high and low tide times, often with corresponding height predictions relative to a mean sea level, such as Mean Lower Low Water (MLLW). These schedules are usually generated through harmonic analysis of astronomical influences, coupled with historical data and local geography.
Accurate tidal predictions are essential for a variety of coastal activities. Mariners rely on them for safe navigation, while tide pool explorers use them to plan visits during low tide, when intertidal zones are revealed. Surfers, swimmers, and fishermen also benefit from understanding tidal currents and their influence on wave conditions. Historically, understanding tidal rhythms has been crucial for coastal communities, influencing fishing practices, port operations, and even settlement patterns. In Laguna Beach, this knowledge continues to be vital for recreational safety and the preservation of the coastal ecosystem.
