Honolulu Tide Range: Which Dates Have the Largest Spread?
Which Honolulu dates have the largest NOAA-predicted tide range over the next 30 days?
The answer
From September 30, 2026 through October 29, 2026, Honolulu, Hawaii's largest listed NOAA turn-to-turn range is 2.559 ft (0.780 m converted) on October 27, 2026. The smallest listed range is 1.306 ft (0.398 m converted) on October 16, 2026.
Across the 30 local dates, NOAA returned 4 dates with 3 listed turns (13%), 26 dates with 4 listed turns (87%). The page preserves those returned counts; it does not add a tide event where the official response supplied none.
How this calculation works
For each local date, this page subtracts the lowest listed NOAA high/low prediction from the highest listed prediction. NOAA supplies feet relative to Mean Lower Low Water (MLLW); metres are conversions from those official feet values.
A listed prediction range is not observed water depth, launch clearance, or a safety guarantee. Wind, pressure, storms, and local conditions can make observed water different.
