Waikiki, HI Daily Water Report — October 4, 2026

Waikiki is a go for diving and sailing, a qualified go for boating, and a choose-your-window day for paddlers and surfers. The water is warm at 27.5 C, total waves are holding near 1.1–1.3 m, and the day’s calmest sea state arrives around 7 AM at 1.14 m. That makes the early daylight stretch the cleanest practical bet before the NE breeze builds and afternoon gusts reach 31.5 knots around 2 PM. Diving leads the board at 8.8/10, supported by warm water, moderate seas and available clarity inputs; that score is not a safety guarantee, and surface conditions can change quickly once the gusts arrive. Sailing rates 8/10, with enough NE wind to work with, but the large gust spread means crews should expect a more demanding afternoon rather than a steady, gentlemanly breeze. Boating remains favorable at 7.1/10, though the short 0.7 m wind waves at 3.25 seconds may add chop beyond what the 0.68 m, 9.3-second south swell suggests on paper. For anglers, the better timing is around the morning solunar major period from 6:38 to 8:38 AM, with the rising tide headed toward an 11:34 AM high of 0.66 m. Fishing scores 6.5/10: decent, but down from yesterday’s reconstructed 6.9 as wind becomes more of a factor. The evening major period, 6:38–8:38 PM, overlaps the 7:12 PM low tide and falls after sunset, so it is less forgiving from a logistics standpoint. Surfing is a modest 4/10 under the regional break model: wave height is present, but the 8.25-second overall period and increasing wind do not point to a standout day. Kayaking is similarly workable only with restraint at 5.7/10; early is preferable, and the afternoon rain window from noon to 7 PM adds another reason not to linger offshore. Atmospheric visibility is near 6 km, with UV high at 7.9. Compared with recent days, diving remains exceptionally consistent, while surfing has slipped well below the stronger scores earlier this week. Monday through Wednesday look lighter-wind with 1.0–1.2 m seas; seas build again late week, reaching 1.5–1.6 m by Saturday. Best bet: get on the water soon after dawn, when the sea is at its calmest and the day has not yet found its gusty personality.
