Pearl Harbor, HI Daily Water Report — September 5, 2026

Pearl Harbor favors the sail and the south swell today, not the paddle. Sailing at 8.3 and surfing at 8.2 outrank a middling 6 for boating, 6.5 for diving, and a 5.2 fishing score, with kayaking last at 4. Those are suitability numbers, not permission slips. A northeast breeze in the 4.8–9.4 knot band, representative near 9 knots and gusting to 21, with a 22.7-knot spike around 13:00, is the engine for sailing when paired with only 15 percent cloud and 1.6–1.8 meter waves. Surfing rides the same 1.7 meter seas at about 10 seconds, plus a 1.22 meter swell at 7.6 seconds from 173 degrees. The day’s calmest water is overnight, 1.6 meters near 00:00; it never really lays down after that. Wind waves stay smaller at 0.54 meters, while a 0.7 m/s current toward 256 degrees adds drift that kayaks and smaller boats will feel. Air is a representative 27.1 C that feels closer to 29.7, ranging 22.5–29.2 C under 74 percent humidity. Marine water is 27.5 C. Drizzle is on the clock from midnight to midnight, yet the representative fall is only 0.1 mm. Atmospheric visibility is 7.52 km; that is not underwater clarity. Pressure holds stable near 1009 hPa, a step below the 1012–1016 hPa stretch of recent days. Fishing’s 5.2 leans on solunar timing, that softer pressure, wind, and available clarity; tide data is simply not in. Major solunar windows run 06:46–08:46 and 18:46–20:46, with a minor at 13:16–14:16. Wildlife at 7.2 uses those hours and the wind. Diving has cooled from the 8.3–8.8 run earlier this week as waves and breeze outweigh still-warm water. Versus yesterday, sailing improved from 7.7 while surfing, diving, and fishing all slipped. Tomorrow through the 8th, rain chances stay very high and waves build toward 2.3–3.6 meters before easing after the 9th. Best bet: take the sail or that south swell this morning, before the midday gust and the larger water that follows.
