The Lowdown
G’day, Rusty here. Look, I gotta be straight with you from the get-go: the next 16 days at Rabbit/Manana Island (Oahu) are a write-off for paddle surfing. There’s no standout session, no hidden gem, nothing. The forecast is a long, grim run of cross-onshore winds that just won’t let up, and the swell is almost all short-period, wind-driven junk. It’s a tough stretch, and I’m calling it as it is.
The whole period starts with a weak, messy combo. From Wednesday 5 August right through the first week, you’re looking at swell heights between 3 ft and 6 ft, all from the ENE, with periods that are a shocking 5 to 7 seconds. The combined wave energy is weak to moderate at best (values between 95 and 355). The wind is a relentless cross-onshore, blowing 15 to 25 mph, which just chops everything up. There’s no clean window, no glassy morning. It’s all poor surf conditions.
Into the second week, from about 12 August, the swell actually starts to build. By 15 August, we’re seeing 7 ft, and it climbs to 10 ft by 18 August. The combined energy gets strong too, hitting 503 on Saturday 15 August and peaking at 1405 on Tuesday 18 August. But here’s the killer: the wind stays a strong cross-onshore, 22 to 28 mph, and it’s messy. The period is still a short 8 seconds, so it’s just a big, lumpy, onshore mess. These waves are blown-out and thumping. For a spot that’s exposed to NNE swell, this ENE wind is just bad news. Honestly, with the size and the wind, this setup looks more interesting for kite surfing than paddle surfing.
The water temp is about average for the time of year, so no drama there.
There’s simply nothing to recommend. The breaks here are fairly consistent, so it’s rare to see such a blank run. It won’t stay this way forever, and forecasts can change, but for now, leave the boards at home.
