Sea Otter Harbor is a subordinate station on the Alaska coast. NOAA derives predictions by applying time and height offsets to a nearby reference station. Its reference station is Sitka. 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 Sea Otter Harbor?
The next high tide at Sea Otter Harbor is shown in the tide clock at the top of this page and in today's tide table, calculated by NOAA for station 9450312. Times are local to Alaska.
What time is low tide today at Sea Otter Harbor?
Low tide times for Sea Otter Harbor 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 Sea Otter Harbor?
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 Sea Otter Harbor 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.
