CatchWindow fishing intelligence

Honolulu, HI Daily Water Report — September 5, 2026

Surfing is the day’s winner around Honolulu, an 8.5 out of 10 that matches yesterday and still rides the strong stretch this week has been scoring. Sailing is the other worthwhile play at 7.7. Boating sits at a cautious 6, fishing slips to 5.6, and wildlife holds a middling 6. Kayaking is the miss at 3.9. Diving is unscored, so it stays off the board. A south swell near 1.5 meters at about 9 seconds is carrying the energy, with overall seas holding 1.7 to 1.8 meters and only a shade quieter around midnight. Wind waves stay under half a meter, so the texture is mostly organized swell rather than local chop. Representative wind is a modest 7 knots from the north-northeast, but that is not the day’s peak: the range runs about 7 to 11 knots, and the strongest gust, 27 knots, is timed near 14:00. That afternoon punch is the main tradeoff, and together with a 0.9 meter-per-second current setting toward the southwest it is why paddling scores stay poor even as surfers get what they came for. High water arrives at 12:04 at 0.68 meters, with lows near 0.1 meters at 03:48 and 19:59. Solunar majors fall 06:46–08:46 and 18:46–20:46. Fishing’s cooler reading also tracks a falling barometer around 1011 hPa, down from the mid-1010s earlier in the week, not a sudden change in the swell. Air starts in the low 20s Celsius and climbs toward 30 under mostly clear skies, humid, with a rain window from 04:00 to 15:00 that still shows no measurable accumulation. Atmospheric visibility is about 17 kilometers; that is not a read on the water column. Marine surface temperature is 26.7°C. Against recent CatchWindow scores, surfing has eased only a tick from the 9-plus marks of September 1–3, while fishing has cooled steadily from the 8s late last week. Sailing is a step off yesterday’s 8.5. Seas then build toward 2 to 3-plus meters by the 7th and 8th as rain chances climb into the 70s, before both wind and swell ease after the 9th. Best bet: take that south swell early, before the afternoon gusts, and leave the kayak on the rack.
