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.
Mendocino, Mendocino Bay is a subordinate station: NOAA computes its tides from Arena Cove with fixed time and height corrections.

On Tuesday, October 27, high tide at Mendocino, Mendocino Bay is at 12:48 AM (4.8 ft) and 11:47 AM (6.8 ft); low tide is at 5:40 AM (2.4 ft) and 6:56 PM (-1.0 ft) (PDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 7.5 ft on December 24, 2026 at 10:09 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 181 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -1.9 ft on June 6, 2027 at 7:14 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. Mendocino, Mendocino Bay is a subordinate station: NOAA derives its times and heights from the reference station Arena Cove with fixed corrections. The curve between highs and lows is our interpolation. This page is not for navigation.
