Orange: measured by NOAA's sensor, last 24 hours (6-minute data, preliminary). Dashed: predicted tide, through the next 24 hours. The prediction contains only the astronomical tide; wind, air pressure and river flow move the real water level away from it.
Eyak River entrance is a subordinate station: NOAA computes its tides from Cordova with fixed time and height corrections.
On Tuesday, October 27, high tide at Eyak River entrance is at 3:01 AM (11.0 ft) and 2:36 PM (13.9 ft); low tide is at 9:19 AM (2.3 ft) and 10:02 PM (-2.5 ft) (AKDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 14.3 ft on November 25, 2026 at 1:16 PM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 181 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -3.8 ft on July 5, 2027 at 10:03 AM. Minus tides expose the most shoreline, which is why tide-poolers look for them.
Station local time (AKDT at the time this page was built), with daylight saving time applied where the area observes it — the same convention as NOAA's own tide tables.
From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. Eyak River entrance is a subordinate station: NOAA derives its times and heights from the reference station Cordova with fixed corrections. The curve between highs and lows is our interpolation.
