CatchWindow fishing intelligence

Pipeline, HI Daily Water Report — August 23, 2026

Sailing, surfing, and diving are the play at Pipeline today, and the rest of the scorecard is more cautious. Sailing leads at 8.9 out of 10, with diving at 8.2 and surfing at 8. Those are suitability ratings from the day’s wind, waves, and related inputs—not a safety clearance. Boating sits at 5.1 and kayaking at 3.3, both punished by the same mix of breeze, short-period wind sea, a 0.7 m/s current toward 284 degrees, and a rain window from 13:00 to 23:00. Fishing is a middling 6.9; wildlife 5.6. The useful stretch is morning into early afternoon. Forecast and current conditions put representative wind at 13 knots from the east-northeast, with a day range of 8.7 to 13.4 knots and the hardest gust, 30.7 knots, timed near 19:00. Waves run 1.6 to 1.9 meters, a representative 1.86 meters at 6.5 seconds, over a 0.74-meter swell at 7.85 seconds from 102 degrees and 1.5-meter wind waves at 4.6 seconds. That is enough energy for the surf score without long-period punch. The day’s calmest reading is 1.62 meters near midnight, so do not wait for a midday flat. Sunrise is 09:14; a solunar major from 10:48 to 12:48 is the better fishing window before drizzle sets in. Representative rain is only 0.1 mm, but the wet hours are long. Air is a humid 28.6 C that feels like 31.5, under 36 percent cloud, with atmospheric visibility near 8 km—that is air clarity, not underwater. Water is 27.1 C, about 0.8 above average, which supports the diving score along with the moderate seas. Chlorophyll is a lean 0.07 mg/m3, blue oligotrophic water, and that does not speak to fish or wildlife. Pressure is 1015 hPa and falling. Against yesterday’s reconstructed scores, fishing dropped from 8.9 and wildlife from 8.4, while surfing and sailing ticked up from 7.7 and 8.6. Looking ahead, Monday and Tuesday keep high rain chances and waves near 1.5 to 1.8 meters; midweek the marine forecast eases toward 1.2 to 1.4 meters and the wet odds finally dip. Best bet: take a morning sail or a short surf before the drizzle and those evening gusts arrive.
