CatchWindow fishing intelligence

Pearl Harbor, HI Daily Water Report — September 6, 2026

Pearl Harbor is a surf-and-dive day, not a paddle day. Surfing leads at 8.5 and diving at 8.3; sailing is a workable 7.3, fishing a middling 6.5, wildlife 6.2. Boating slips to 5.1 and kayaking to 3.8. Those are suitability scores, not permission slips, and the water will still charge you for inattention. The window is morning. Waves hold 1.7 to 1.9 meters, calmest near 07:00 at 1.7 meters, with a 1.44-meter swell at 8.9 seconds from 190 degrees and shorter wind waves of 0.82 meters. Representative wind is 9 knots from the east-northeast in a 5.4–9.8 knot range, but the strongest gust, 23.3 knots, is due at noon. Rain is forecast from 09:00 through 23:00, a light 0.3-millimeter drizzle under 90 percent cloud, with atmospheric visibility only 3.56 kilometers—air, not underwater. Dawn is 05:55, sunrise 06:17. If you are fishing, the morning solunar major runs 07:50–09:50; the score leans on that timing, stable 1009-hectopascal pressure, wind, and available clarity. Tide data are unavailable, so do not invent a tide story. A 0.7 meter-per-second current toward 270 degrees is the quiet tax on small boats and kayaks. Water is 27.1 C, 0.4 C above average; marine readings show 27.5 C. Chlorophyll is a lean 0.07 mg/m3, oligotrophic blue water, which says nothing about fish. Against CatchWindow’s recent run, surfing sits with yesterday’s 8.2 and the 8.5 on the 4th after higher 9s earlier in the week. Diving rebounds from yesterday’s 6.5 to match the 8.3 of the 3rd and 4th. Fishing is firmer than yesterday’s 5.2 but well off the 8s from August 30 through September 1. Sailing and boating both ease from yesterday. Seas get louder tomorrow: forecast waves 1.9–4.4 meters on the 7th and 2.1–4.4 on the 8th, with rain chances at 100 percent through the 9th before winds slacken and heights fall toward 0.8–0.9 meters by the 12th. Best bet: take the 1.7-meter morning for a surf or a dive, then let the building swell own the week.
