On Tuesday, October 27, high tide at Rosario, East Sound, Orcas Island is at 7:34 AM (8.0 ft) and 4:28 PM (7.8 ft); low tide is at 11:59 AM (6.0 ft) (PDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 9.7 ft on December 25, 2026 at 7:20 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 188 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -3.4 ft on July 4, 2027 at 11:25 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.
