Magens Bay, St. Thomas is a harmonic reference station on the Puerto Rico coast. NOAA computes predictions directly from decades of water-level observations here. Predictions on this page are astronomical — driven by the Moon and Sun — and do not include wind, pressure or storm surge. Where NOAA operates a live sensor, the water level reading shows the real tide right now, which is the best check on conditions.
What time is high tide today at Magens Bay, St. Thomas?
The next high tide at Magens Bay, St. Thomas is shown in the tide clock at the top of this page and in today's tide table, calculated by NOAA for station 9751693. Times are local to Puerto Rico.
What time is low tide today at Magens Bay, St. Thomas?
Low tide times for Magens Bay, St. Thomas appear in today's tide table and on the day timeline, together with the predicted height in feet above Mean Lower Low Water (MLLW).
When is the best time to visit the beach or tide pools at Magens Bay, St. Thomas?
Aim for the 90 minutes either side of a daylight low tide — the 'Beach · tide pools' window on this page. The lower the low, the more sand and rock is exposed; spring tides around new and full moon give the lowest lows.
How accurate are Magens Bay, St. Thomas tide predictions?
NOAA's astronomical predictions are typically within a few inches and minutes under normal weather. Strong wind, storm surge and river discharge can push the real water level above or below the prediction, so check the observed level where a live sensor exists.
What does MLLW mean?
Mean Lower Low Water is the average of the lower of the two daily low tides over a 19-year period. A reading of 0.0 ft is a normal low; negative values are unusually low tides.
