Mokuoloe, HI Daily Water Report — August 27, 2026

So, is it a go? For most of you, yes—with the caveat that this is a day of trade-offs. The wind is the story, and it’s a classic double-edged sword. Let's start with the best bets. Diving scores an 8.5, and that’s the standout. The water is clear blue oligotrophic, and the surface is manageable, though not glassy. The representative wave height sits at 1.46 meters on a short 6-second period, but the real issue is the wind. Expect a steady 9 knots from the east-northeast, gusting into the low 20s by mid-afternoon. That means your best window for any on-the-water activity is the early morning, before the seabreeze really cranks. For divers, the morning offers the calmest conditions and the best chance of decent underwater visibility—the surface chop and particulate suspension that kicks up later will degrade it. Surfing scores a 7.5, and while the swell is modest at 1.12 meters from 72 degrees, the short period means it’s a choppy, wind-affected wave. It’s rideable for the experienced, but not a clean, lined-up day. The real winner is sailing, scoring an 8.9. That strong, consistent ENE wind is exactly what a sailor wants—just be aware the gusts are significant, so reef early. Boating scores a 6.9, perfectly fine for powerboats, but a bumpy ride for smaller craft in the afternoon. Kayaking scores a 5.2. The wind and chop will make it a workout, not a leisurely paddle; stick to sheltered leeward shores if you go. Fishing scores a 6.5—a decent, not great, day. The solunar major period around 10:57 to 12:57 aligns with building wind, but stable pressure and blue water offer a solid baseline. The waxing gibbous moon, nearly full at 98%, will mean brighter nights and possibly less active daytime feeding. Wildlife observation scores a 7.2, and the steady easterly wind and the solunar minor periods around dawn and dusk are your best bets for spotting activity on the surface. The next few days see a clear trend: the trade winds hold steady, but more importantly, the chance of rain increases sharply, hitting the 80s by Friday and staying there through the weekend. The wave heights begin to build, climbing toward 1.8 meters by Monday, with a longer period developing. That suggests a new swell is on the way, likely from the northeast. This is your last truly calm day in the wave department for a while. Best-bet sentence: Get on the water at dawn for the smoothest ride and the clearest view—after that, the island’s breath picks up and the ocean talks back.
