Honolulu, HI Daily Water Report — October 6, 2026

Honolulu gets a clear green light for most water plans, with diving and boating leading the card—but the afternoon gust bump is the part that deserves your attention, not your optimism. The marine picture is orderly: waves hold near 1.1 m, driven mostly by a long-period 1.02 m south swell at nearly 12 seconds. That is enough moving water to keep shoreline entries and exits honest, especially where the south-facing swell has room to work, but the short wind-wave component is only 0.18 m. NNE winds run a generally manageable 4 to 8 knots, though gusts could reach 19.4 knots around 3 PM. Boating rates 8.1/10 and kayaking 7.3/10 under the supplied wind, wave, current, and precipitation inputs; early day is the cleaner bet before the gustier stretch develops. Diving earns the day’s top score at 8.8/10. Marine SST is 27.2 C, 0.6 C above average, with low chlorophyll at 0.07 mg/m³. That supports the diving model’s favorable water-temperature and available-clarity inputs, but it is not an underwater-visibility report; surface atmospheric visibility near 16.7 km tells you nothing reliable about what the water looks like below. The 1.1 m swell still makes site exposure and entry conditions the deciding details. For anglers, the 6.1/10 fishing score is respectable rather than electric. The more useful timing is the 8:26–10:26 AM solunar major period, with the rising tide building toward the 1:14 PM high of 0.64 m. A second major period runs 8:26–10:26 PM, after the 8:03 PM low. Pressure is falling from around 1013 hPa, and a brief rain window is forecast from 1–4 AM, so dawn may be damp even though representative precipitation is zero. Compared with the recent run, boating improves slightly from yesterday’s 7.9, while sailing slips from 7.6 to 6.9 as the gust spread becomes less forgiving. Kayaking also improves from 6.7, and diving returns to a strong modeled score after no score was available yesterday. Wednesday stays similarly low-wave but turns wetter; Thursday looks wetter and rougher, with waves up to 1.5 m and winds to 14.2 knots. Friday eases the wind but remains showery, while the weekend trends steadier. Best bet: launch or splash in early, use the rising morning tide, and be back with a dry bag packed before the 3 PM gusts start acting like they own the place.
