The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for James Kealoha Beach Park.
To be straight with you, the next week or so is looking pretty frustrating. We’ve got a run of poor conditions and marginal surf that’s just not going to get you excited. The first proper window where you might want to start paying attention doesn’t open up until Wednesday, 2nd September, with a bit of a pulse. But even then, the wind is messy.
The standout period, the one that’s got my heart beating a little faster, is Thursday, 10th September. That morning, James Kealoha Beach Park (Hawaii) sees a 6ft swell from the east, with a solid 13-second period -- proper groundswell energy. The combined energy is strong at 1049, so you’ll feel the push. What’s really got me hopeful is the light cross-shore wind, meaning those waves should be reasonably clean. This is a reef break, and with that longer period, expect well-shaped lines, but remember, it’s a beginner-friendly spot, so the crowd might be around. It’s not huge, but it’s the best we’ve got. The water temperature is 82°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.
Before that, Wednesday, 2nd September morning shows a 6ft swell from the east-northeast, also with moderate energy (813), but it’s a shorter 8-second period and the wind is cross-shore. It’s worth a look if you’re keen, but it’s more of a gamble.
For the rest of the time, it’s pretty grim. We’ve got days of cross-onshore winds and short-period, weak swell. Honestly, from now until the end of August, and even into early September, you’re better off leaving the board at home. There are stretches of 3-4 days with nothing worth paddling out for. The surf is small, choppy, and the energy is low, mostly in the 150-200 range. It’s a tough run.
If that Thursday session comes together, it could be a sweet little window. Mark it in your calendar. Otherwise, it’s a waiting game.
Rusty.
