About tides at Honolulu (Oʻahu), HI

Honolulu has one of the smallest tide ranges of any major US harbour — mean range about 0.5 metres. The pattern is mixed semidiurnal, leaning diurnal: most days show one clear high and one clear low, with a smaller secondary cycle that often barely registers. That makes the signal subtle but the timing matters for anyone snorkelling at Hanauma Bay, paddling outside Ala Moana, or watching the reefs at Waikīkī. The lowest tides of the month — around new and full moons — can pull water off the inner reef enough to expose limu beds and tide pools that stay covered most days. Pacific swell from the north and west can push water levels above predicted any time of year, and the trade-wind setup against the southern shore lifts the gauge a few centimetres on a steady afternoon. Predictions come from NOAA CO-OPS station 1612340 in Honolulu Harbor — harmonic predictions calibrated on the local gauge record. Tsunami events, when they happen, completely override the tidal signal; NOAA's Pacific Tsunami Warning Center is the authoritative source for those.

Common questions about tides at Honolulu (Oʻahu), HI

When is the next high tide at Honolulu?
The hero block above shows the next high tide at Honolulu Harbor in local Hawaiian time. The 7-day table breaks out all the daily extremes — note that on diurnal-leaning days, the secondary high or low may be only a few centimetres different from a flat plateau.
Why is the tide range so small in Hawaiʻi?
Hawaiʻi sits in the deep central Pacific far from continental shelves. The astronomical tide forcing is small here because the islands aren't on a resonant tidal basin. Mean range is about 0.5 m at Honolulu, and the daily pattern leans diurnal — often just one meaningful high and one meaningful low. Bigger swells and storm setup from the open ocean can dwarf the astronomical signal.
When are the best low tides for snorkelling at Hanauma Bay?
Lower tides expose more reef and shorten the swim out, but at Hanauma the inner-reef snorkel is rewarding across most tides. The biggest lows happen around new and full moons. The 7-day table on this page flags each day's lowest predicted tide; cross-reference Hanauma Bay Nature Preserve's hours and entry rules separately.
Where do these tide predictions come from?
NOAA CO-OPS station 1612340, Honolulu Harbor. NOAA's harmonic predictions for Hawaiian stations are accurate but the small absolute range means even small deviations look proportionally larger than they would on the East Coast. Wind, swell, and rainfall can each shift water level by a few centimetres.
Is this safe to use for navigation?
No. Use NOAA's official chart and tide products plus US Coast Guard notices for piloting in Honolulu Harbor. For tsunami threats — which override normal tidal predictions completely — the Pacific Tsunami Warning Center is the authoritative real-time source.
