Heights in feet above Mean Lower Low Water (MLLW). Dots are NOAA's predicted highs and lows; the line between them is our interpolation. Shaded: night.

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.
Waimanalo is a subordinate station: NOAA computes its tides from Moku O Loe with fixed time and height corrections.
On Tuesday, October 27, high tide at Waimanalo is at 3:51 AM (2.4 ft) and 2:00 PM (1.3 ft); low tide is at 9:58 AM (0.8 ft) and 8:51 PM (-0.3 ft) (HST, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 2.5 ft on December 24, 2026 at 3:48 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 187 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -0.6 ft on December 23, 2026 at 7:48 PM. Minus tides expose the most shoreline, which is why tide-poolers look for them.
Station local time (HST 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. Waimanalo is a subordinate station: NOAA derives its times and heights from the reference station Moku O Loe with fixed corrections. The curve between highs and lows is our interpolation.
