The Lowdown
Alright folks, Rusty here. Let’s get into it. We’re looking at a solid 16-day window, but I gotta be straight with you – it’s a bit of a grind for most of it. The trade winds are stubborn, and that’s gonna keep things messy for a while. The real standout is tucked away in the second week, but you’ll have to be patient.
First up, the only spot that’s even on the radar is Tennis Courts. It’s a reef break, so it’s got that going for it, but it’s advanced territory and fairly consistent. The problem is the wind. We’ve got a relentless cross-offshore breeze from the ENE that’s going to be pumping at 19 to 28 mph for days on end. That’s a fresh to strong breeze, and while it’s cross-off, it’s not going to make for a relaxing session.
Starting Saturday, August 8th, it’s a no-go. We’ve got a tiny 2 ft swell from the SW with a long 18-second period, but the energy is weak (419) and the combo of small size and heavy wind just makes for poor surf. This theme continues right through the week. From Sunday the 9th to Thursday the 13th, we’re looking at marginal surf at best. Swell sizes bob around between 5 ft and 5 ft, mostly from the ENE, with the occasional hint of S and SSW groundswell. The combined energy picks up a bit, hitting over 900 on Wednesday, and even over 1000 on Thursday morning, but the wind is just too strong. It’s clean, but raggedy. The water temp is about average for this time of year, nothing unusual.
Now, here’s where it gets a bit wild but also a bit useless. From Friday the 14th through to Sunday the 16th, the swell really kicks in. We’re talking 8 ft on Friday, jumping to 13 ft on Saturday, with the combined energy going through the roof – 2816 on Saturday morning, and peaking at 3863 on Sunday morning. That’s very strong wave energy. But the wind is still a strong breeze at 25-28 mph, and the period is short (8-9 seconds) from the ENE. That combo is a recipe for lumpy, blown-out, and dangerous conditions. At that size, over 8 ft, it’s experts only, and even then, that wind is a killer. This setup looks more interesting for kite surfing than paddle surfing.
The best chance for a decent wave comes on Sunday, August 16th. The morning has a solid 10 ft swell from the S with a long 12-second period, and the energy is massive (3863). This is a true groundswell. The wind is still a strong cross-off, but it’s the stand-out in the whole run. The long period from the south is best for a reef, so Tennis Courts could handle it. But be warned, at 10 ft, this is strictly for experts. The crowds are listed as “sometimes,” so you might get a few others out there, but with that wind, it won’t be a circus.
After that, the surf drops off quickly. Monday the 17th sees a 6 ft ENE swell, but the energy is down to 614, and the wind is still fresh. The rest of the week into the 23rd is a mix of tiny 1 ft SSW pulses and junky 5 ft ENE windswell, all with that same cross-off wind. Nothing worth paddling out for.
So, to sum it up: the only real standout is Sunday morning, August 16th. The 10 ft south swell with very strong energy is the one to watch, but it’s a big, windy, expert-only affair. The rest of the 16 days is a write-off. A long gap of poor to marginal conditions. It’s a tough outlook, but that’s the way the trades are blowing.
Rusty.
