Honolulu runs mixed-semidiurnal water: two highs and two lows daily, unequal by ~0.7 ft between successive highs this week. The tide here is gentle — the water moves about 1.4 ft between high and low on an average swing this week, so timing matters less than on big-tide coasts. A 2.2 ft swing — Honolulu's biggest this table — runs from the 7:25 AM low on Tue Sep 8 into the next high. Honolulu tops out at 2.4 ft (Tue Sep 8 2:27 PM) and bottoms at 0.1 ft (Fri Sep 11 10:32 PM).
Honolulu mid-swing times below mark predicted peak flow on its 1.4 ft average cycle (why moving water matters):
Sea surface temperature 22 km away at Oahu Hawaii is currently 27.1 °C (80.8 °F), 0.2 °C above the seasonal normal, from satellite and ocean-model data refreshed daily.
Honolulu numbers: NOAA CO-OPS #1612340 (Honolulu), 0.9 km off Honolulu center; this open-water pick beat 6 closer-in candidates. With only 1.4 ft of average swing at Honolulu, wind and pressure can move the real water line more than the tide itself does — treat these times as the schedule, not the whole story.
