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.

On Tuesday, October 27, high tide at Armitage Island, Thatcher Pass is at 7:31 AM (8.0 ft) and 4:23 PM (8.1 ft); low tide is at 11:30 AM (6.3 ft) (PDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 9.3 ft on December 25, 2026 at 7:17 AM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 197 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -3.7 ft on July 4, 2027 at 11:02 AM. Minus tides expose the most shoreline, which is why tide-poolers look for them.
Station local time (PDT 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. The curve between highs and lows is our interpolation. This page is not for navigation.
