The Lowdown
Alright gang, Rusty here. Let’s talk about what’s cooking for our local spot. It's gonna be a quiet one for a while.
The big picture is a whole lot of trade wind misery. For days on end the ENE wind is up, blowing cross or cross-onshore, just tearing up the surface. Water temp sits at 27°, right where you'd expect it to be this time of year.
The first real event doesn't hit until Sunday, August 16th, and it's a beast. A serious ENE groundswell rolls in at 21 to 23 feet, with a period of 11 to 13 seconds. The power is insane (15266). Anything over 8 feet is big; this is only for the brave. On Sunday morning the wind is a strong cross-offshore from the SSE, actually cleaning it up, and by the afternoon it goes to a clean offshore. But the catch is the forecast says the swell is simply too big for Rabbit/Manana Island. Unless you’re a big-wave charger, it’s a stay-on-the-cliffs day.
Your one and only true window comes on Monday, August 17th. The swell settles to a nice 6 ft from the ENE (9-second period), and the morning breeze is a light 15 km/h from the SSE, described as a gentle breeze and clean (455 energy). That’s the standout of the whole 16 days. It’s a fairly consistent wave here, but it can get a crowd sometimes, so get out there early. The direction is decent, even if it's not the absolute ideal NNE. Clean and 6 ft? That’s the best we’ve got.
After that high point, we sink back into an 8-day slump from Tuesday the 18th through Tuesday the 25th. The wind stays locked in from the ENE and NE at 25 to 40 km/h, cross or cross-onshore. The swell never gets above 5 ft and is all short-period windswell (6 to 8 seconds). Forget it – it’s choppy, lumpy, and frustrating.
If you’ve got a kite, the stretch around the 14th and 15th with 6 to 11 ft of swell under a solid cross-onshore breeze looks way more fun than anything on a paddleboard.
So, one huge, expert-only day on the 16th, and one good, surfable morning on the 17th. Don't sleep on it.
Rusty.
