Pipeline, HI Daily Water Report — August 28, 2026

Diving is the standout play today with an 8.6, and the early morning window before the wind ramps up is your best bet across the board. A full moon overhead and a low tide just before 10 a.m. combine to make the 6 a.m. to 9 a.m. slot genuinely special for anyone who can get in the water. The east wind is holding around 8 knots with gusts pushing 17, and those gusts are forecast to peak near 28 knots around 10 a.m., so the window tightens as the morning wears on. Wave heights sit at a consistent 1.3 meters with a short 6-second period from a nearly due-east swell, which means the surface will be busy but not chaotic, especially compared to the bigger, longer-period days earlier in the week. Sailing scores an 8.3, and while that might seem surprising given the gusty forecast, the steady trade direction and moderate average wind actually make for a solid afternoon if you can handle the puffs. Just keep an eye on that 10 a.m. gust spike. Surfing comes in at 7.7, which is essentially the same as the past few days—the wave height hasn’t budged much, and the swell direction is consistent with what we’ve seen since midweek. The trade winds do add some texture to the face, but for a summer day at this break, it’s workable. Boating scores a respectable 6.9, though the chop and those late-morning gusts will test smaller craft. Kayaking sits at a 5.2, and that’s the one to skip unless you’re an expert paddler—the current pushing west at half a meter per second and the afternoon wind will make for a workout. The water temperature is running 27.4 degrees, which is more than a degree above the historical average, and the chlorophyll reading is extremely low at 0.07 mg/m3. That’s textbook blue water, and for divers it means exceptional visibility—likely 60 feet or more. The fishing score of 7.3 reflects the solunar timing being decent but not peak, with the major period falling in the middle of the day when the wind will be strongest. Looking ahead, the pattern shifts toward wetter conditions starting tomorrow, with precipitation chances climbing above 80 percent through the end of the month and wave heights building to 1.8 meters by Saturday. The swell direction is forecast to rotate more northerly, which could change the character of the break entirely. If you want the best of what this week has left, get out there before the morning breeze turns into a blow.
