Tinian Island is a subordinate station on the Guam coast. NOAA derives predictions by applying time and height offsets to a nearby reference station. 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 Tinian Island?
The next high tide at Tinian Island is shown in the tide clock at the top of this page and in today's tide table, calculated by NOAA for station TPT2625. Times are local to Guam.
What time is low tide today at Tinian Island?
Low tide times for Tinian Island 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 Tinian Island?
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 Tinian Island 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.
