The Lowdown
Alright, Rusty here. Let's break this down in feet and miles per hour, the old-school way.
Honestly, the story’s the same – it’s a tough start. From Monday the 24th right through the end of August, you’re not gonna want to paddle out. We’re talking weak, short-period windswell and a cross-shore breeze that’s making everything look like a washing machine. The wave energy figures are all over the place (49-272), but none of it translates to clean, rideable waves.
The first real chance for a good session doesn’t come until Tuesday, the 1st of September. That morning at The Reef (Culebra), the wind will be light and from the southeast, which is a cross-off breeze. That means the surface will be clean. You’ve got a solid 3 to 4 ft swell (1.0m) rolling in from the east-northeast. The wave energy is a decent 313. It’s a very consistent break, so you’ll be getting plenty of waves, but expect it to be a popular spot with the local crew.
That little window of clean, chest-high swell holds into Wednesday and Thursday mornings (2nd and 3rd) – same swell height, same clean wind. The wave energy stays solid (306-341). The period is around 11-12 seconds, meaning it’s a real groundswell with some proper push. For that reef, it’s a sweet spot.
After that, from the 4th of September onwards, it fades hard. Friday morning drops in energy and gets a bit messy again. The second week of September looks pretty weak and inconsistent, with wave energy numbers dropping to 58-133. The wind stays okay, but there’s just no swell to work with. The next Monday is small, maybe knee-high at best.
So the takeaway is clear: hold out for the 1st of September. That morning is your best bet out of a pretty quiet 16-day run.
Rusty, out.
