King tides in Puerto Rico, 2027

The biggest predicted tide in Puerto Rico in 2027 reaches 2.3 ft above MLLW at Boca del Cibuco on Tuesday, November 16, at 10:35 AM local time. Below are all of the year's king tide windows — the top 1% of predicted highs — for NOAA reference stations along the Puerto Rico coast. King tides are perigean spring tides: they arrive when a full or new moon lines up with the moon's closest approach to Earth, and they preview the flooding that sea level rise will make routine. Read how king tides work.

NOAA CO-OPS harmonic predictions, datum MLLW, station local time. Actual water level can run higher with storms, onshore wind, and low pressure — king tide + storm is the flooding combination to watch. Predictions are for planning, not navigation.
