King tides in Puerto Rico, 2026

Published NOAA almanac

Showing the verified representative-station calendar

The live multi-station refresh did not finish inside the response window, so this page is using Perigee's checked-in 2026 almanac. It was generated from the complete NOAA prediction year for one established reference station in Puerto Rico.

The biggest predicted tide in Puerto Rico in 2026 reaches 2.1 ft above MLLW at SAN JUAN on Wednesday, October 28, at 10:48 AM local time. Below are the published representative station'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.
