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.
Trinidad Harbor is a subordinate station: NOAA computes its tides from Crescent City with fixed time and height corrections.

On Tuesday, October 27, high tide at Trinidad Harbor is at 1:09 AM (6.0 ft) and 12:20 PM (7.8 ft); low tide is at 6:19 AM (2.4 ft) and 7:22 PM (-1.4 ft) (PDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 8.6 ft on December 24, 2026 at 10:43 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 179 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -2.2 ft on June 6, 2027 at 7:38 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. Trinidad Harbor is a subordinate station: NOAA derives its times and heights from the reference station Crescent City with fixed corrections. The curve between highs and lows is our interpolation.
