On Tuesday, October 27, high tide at Hanbury Point, Mosquito Pass, San Juan I. is at 7:25 AM (7.5 ft) and 4:21 PM (7.6 ft); low tide is at 11:23 AM (6.0 ft) and 11:50 PM (-2.1 ft) (PDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 9.0 ft on December 25, 2026 at 7:09 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 196 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -3.2 ft on June 6, 2027 at 11:57 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.
