CatchWindow fishing intelligence

Kawaihae, HI Daily Water Report — October 6, 2026

Kawaihae gets a clear green light for diving, boating and kayaking today, with the caveat that the afternoon has a little more attitude than the gentle headline suggests. A steady 0.5 m sea and long-period 0.38 m southwest swell at nearly 13 seconds keep the water comparatively orderly, while the 28 C marine temperature is a notably warm +1.1 C above average. Diving leads the board at 9.2/10, with boating at 8.7 and kayaking at 8.3; those are strong suitability estimates, not a substitute for site-specific judgment. The best all-around water window is early through late morning, particularly around the 8:18–10:18 AM solunar major period. Winds are light overall, with a representative ENE breeze of 5 knots, and the tide is building from the 6:30 AM low toward the day’s 0.69 m high at 1:14 PM. For anglers, that rising-water stretch overlaps the day’s strongest solunar window and supports a respectable 6.1/10 fishing score. The 2:48–3:48 AM minor period and 2:48–3:48 PM minor period offer secondary timing, while the evening major period runs 8:18–10:18 PM just after the 8:08 PM low. Do not let the representative wind number do all the talking. Gusts are forecast to reach 22.2 knots around 2 PM, making the post-high-tide afternoon a less appealing time for exposed paddling, small-boat handling, or relaxed sailing. Sailing sits at 6.1/10: workable, but gust spread matters more than the average breeze. The current forecast is modest at about 0.11 m/s toward 63 degrees, though local conditions can differ. Atmospheric visibility is forecast at only 0.22 km; that is not an underwater-visibility reading. There is no rain window indicated, and the low chlorophyll reading describes oligotrophic, blue-water conditions rather than a promise of marine activity. Compared with the recent CatchWindow run, diving remains consistently excellent, while boating and kayaking ease slightly from the exceptionally calm October 4–5 stretch. Fishing also trails yesterday’s stronger 7.1 score. Wednesday stays fairly manageable before seas build to 0.7–1.0 m Thursday and around 0.8 m Friday, with higher rain chances later in the week. Best bet: launch early, use the rising tide, and be back in before the afternoon gusts decide they own the place.
