CatchWindow fishing intelligence

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

Pearl Harbor gets a clear nod for boating and diving today, with kayaking and sailing also workable if you treat the afternoon gusts and steady swell with appropriate respect. It is not a glass-flat day, but it is a generally manageable one: winds run light from the NNE at roughly 3 to 7 knots, while the broader sea state holds near 1.1 to 1.2 meters. The catch is the long-period southerly swell—about 1.04 meters at 11.8 seconds—which can make exposed water feel more purposeful than the wind alone suggests. The best all-around window is early, from dawn through late morning. Winds are lighter before the 1 PM gust peak, when gusts may reach 16.7 knots, and the sea is near its daily minimum around midnight rather than building dramatically through the day. For paddlers, that means an early launch and a conservative turnaround plan; the 0.31 m/s current toward the east adds another small but real piece to route planning. Boaters have the day’s strongest score at 7.8/10, while sailing earns 6.9/10: enough breeze for moving, not necessarily enough for effortless light-air sailing. Diving leads the board at 8.8/10, matching the strong recent run and improving sharply from yesterday’s 7.1. Water is warm near 27.4 C, about 0.7 C above average, and wind-wave chop is only 0.18 meters. That said, the reported 2.58 km atmospheric visibility is not an underwater-visibility reading, so don’t confuse a hazy horizon with a dive forecast. The 1.1-meter swell remains the main tradeoff for entries and exits. Fishing is a middling 6.1/10, with the more favorable timing centered on the 8:26–10:26 AM solunar major period and the 1:25 PM high tide. Wildlife’s 7.4/10 also gets useful timing around that morning major period, though its score is not a guarantee of encounters. Compared with recent CatchWindow estimates, boating is nearly unchanged from yesterday, kayaking is just a touch lower, and fishing has softened from the stronger October 3–5 stretch. Pressure is falling from 1013 hPa, another reason not to oversell the day. Wednesday stays similar but wetter, while Thursday looks breezier, wetter, and rougher at 1.3–1.6 meters. Best bet: make the morning your water window, and let the afternoon gusts keep their own appointment.
