Check the water yourself

Conditions can change quickly. Look at the water before going in, and follow lifeguards, posted signs, and closures.

CoveCheck is a forecast, not a safety assessment. It cannot see the shoreline entry, surge, water clarity, or every local hazard. Children and weaker swimmers need a more cautious choice than the forecast alone suggests.
