The Lowdown
Alright, Rusty here, let's see what we've got.
Alright, listen up. The forecast for this spot is a bit of a slow burner. We've got a gap right at the start, so there's no point paddling out for the first few days. The first real chance to get wet doesn't show up until Wednesday afternoon, the 2nd of September.
Ponta Do Rapa (Ponta-Do-Rapa) is a reef break, and it's a tricky one – it rarely breaks, so when it does, you need to be on it. The water temp is about average for this time of year, nothing unusual there.
Wednesday the 2nd of September afternoon is where it starts to get interesting. We've got a clean 6 ft swell rolling in from the SE at a 10-second period, with a light offshore easterly wind at 6 mph. That'll be the first proper look, and it's a good one, with moderate wave energy (644). It's not huge, but it'll be shapey and clean for those who know the lineup. Remember, this is a reef and it's for advanced surfers only.
The real standout, though, comes a bit further out. Keep your eyes on Saturday the 12th of September afternoon. The combined energy is very strong (1402) with a 7 ft swell from the south at a long 12-second period. This is a proper groundswell. With a light SSE cross-off breeze, the conditions will be clean. It's a lot of juice for a reef, so this is for the experienced crew. You'll feel the power in the water, and those long-period lines will push right through. It's the best on offer across the whole period.
The following day, Sunday the 13th of September morning, pumps up a bit more with an 8 ft swell from the south at a very long 13-second period, and the energy is huge (2287). This is expert-only territory. The wind is a moderate cross-off, so the surface should be clean, but that kind of size and period on a reef is serious business.
After that, things settle down slowly through the second week with smaller, cleaner swells, but nothing that beats that Saturday session.
Signing off from the beach.
