The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
We’re looking at a stretch where the surf is pretty much just hanging around at James Kealoha Beach Park. It’s a reef break, exposed to the swell, and it’s fairly consistent, so it’s not a total write-off, but you’ll have to be patient. The water temperature is sitting at 81°F which is a touch warmer than average for this time of year, so you can leave the thick rubber at home.
The first real chance to get something decent is on Sunday, the 6th of September. The morning session is looking like the pick of the whole run. We’ve got a clean 7 ft swell from the ENE, with a solid 12-second period, and the wind is light and cross-offshore. That’s a recipe for some clean, lined-up waves. The energy is strong (1255) and the conditions are described as excellent for experienced surfers, which means it’s got some push to it. This is a real standout, but it’s not a beginner wave at that size. The afternoon holds similar promise with a 7 ft swell and clean conditions, though the wind might shift a little.
After that, it’s a bit of a mixed bag. The swell drops off from Monday, the 7th, and the wind picks up, turning choppy. We go through a few days of marginal surf, with the swell dipping below 3 ft on Wednesday the 9th. The energy drops right off (404) and the conditions get messy. That stretch from the 7th through the 10th is pretty much a no-go for quality surf.
Things start to look a little more interesting again around Friday the 11th, with a 6 ft ENE swell and a 12-second period. The energy is back up (775), but the wind is cross-onshore, so it’s not going to be glassy. Still, it’s rideable. The weekend of the 12th and 13th is a bit of a washout with rain and choppy conditions, so don’t get your hopes up.
Looking further out, the pattern is similar. There’s a bit of a pulse on Tuesday the 15th with a 7 ft ENE swell and a 9-second period, but the wind is all over the place and the energy is moderate (627). It’s a gamble. The very end of the forecast, on Saturday the 19th of September, shows a glimmer of hope with a glassy morning and a 4 ft ENE swell. The energy is weak (321), but if the wind stays glassy, it could be a fun little session on a small board.
So, to wrap it up: the standout is Sunday morning, the 6th of September. Get out there early for the cleanest, most powerful waves of the run. The rest of the period is a waiting game, with a few smaller, wind-affected windows that might be worth a paddle if you’re desperate. It’s not going to be pumping, but it’s not dead either.
Rusty.
