The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for Crouching Lion.
Right off the bat, I gotta be straight with you – this stretch is a tough one. For nearly the first ten days, we are battling a relentless onshore flow. It’s not just a little bumpy; it’s the kind of cross-onshore chop that makes a point break feel like a washing machine. The wave energy is there – we see readings like 635 in the middle of the first week up to a big 1706 on the Saturday – but the wind just ruins it. That water temp is sitting at 80°, dead on average for this time of year, which is nice, but you won't be enjoying it much with that wind in your face.
Crouching Lion (Koolauloa) is an inconsistent spot that needs a very specific east-northeast groundswell, and while the size is there – pushing 6ft to 7ft in the first week – the wind is mostly a fresh breeze from the east-northeast. We get a short period swell of 7 to 8 seconds, so it’s just a messy, lumpy wall of water. Not what you want on a point break.
The one true standout, the only real window worth getting excited about, is around the 12th and 13th of September. Things finally ease off. The wind drops to a light breeze, and the wave energy is still respectable at 782 on the Saturday morning. You'll see a 6ft swell from the east-northeast with a long period of 12 seconds – that’s proper groundswell energy that will line up nicely on the point. It’s clean, with just small crossing ripples. This is the best on offer. It’s a *maybe* – it’s a week and a half out, so keep an eye on it, but the potential for a glassy session is there.
After that, it fades fast. By the 14th, swell drops right off to under 3ft. A few more marginal days midweek, but then it tries to rebuild on the 17th with 7ft from the east, but the cross-onshore wind comes back with it. Honestly, for most of this forecast, if you paddle out you’ll be battling the chop and the crowds that can show up there; it’s not worth it. Kite surfers might have a field day with the constant wind and lumpy conditions, but for us stick-wavers, it’s a waiting game.
For the second week, that window on the 12th and 13th is your only real shot. After that, the energy drops right off. It’s a classic case of watching and waiting for the trade winds to ease.
Rusty.
