The Lowdown
G’day, Rusty here. Honestly, the next week and a half is a bit of a mixed bag for Ponta Do Rapa, but there are a couple of moments that’ll get the blood pumping. This is a proper advanced reef break, and it rarely breaks, so when it does, you need to be ready. The water temp is sitting at 65°F, which is pretty normal for this time of year, nothing wild there.
The first few days are a write-off, really. Friday the 28th is a no-go with a messy 6ft NE swell and a cross-shore wind. Saturday the 29th cleans up a bit with a 5ft ENE swell and clean conditions, but it’s ordinary stuff – not worth paddling out for. Sunday the 30th sees light rain and a tiny 4ft E swell, with a glassy moment in the afternoon that’s tempting but the size just isn’t there. Monday and Tuesday (31st & 1st) stay small and mostly poor.
Now, Wednesday the 2nd of September is where it gets interesting. A big 10ft S swell rolls in, with a period of 11 seconds and a serious swell energy of 3544 – that’s proper strong. But it’s a bit of a beast; that size is only for experienced crew, and the wind is light and cross-shore, so it’ll be a bumpy drop. Not the stand-out, but it’s the first real pulse.
The first true standout comes on Saturday the 5th of September. The morning sees a 6ft S swell with a glassy wind – dead calm. The energy is solid at 504, and it’s a clean, offshore-friendly direction. For a break that rarely works, this is a magic little window. Get there early.
Then, hold onto your boardies, because the best is yet to come. The week of the 7th starts to build, but the real gem is Thursday the 10th of September. The morning brings a 4ft SE swell with a huge 16-second period – that’s very long period groundswell, packing a strong energy of 1656. The wind is offshore from the ESE, and it’s described as excellent surf conditions for experienced surfers. This is the best on offer. That long period will draw right down the reef, making for some proper walled-up bombs. Just remember, a long period like that needs the right take-off spot.
Friday the 11th sees another massive 10ft SSE swell, but the energy is huge (2803-2633) and it’s likely too big for most, even with clean wind. Saturday the 12th brings it back into the sweet spot: 7-7ft SE swell with light offshore winds and clean conditions – another very good day, but the Thursday is the real standout.
There’s a gap from the 13th onward with nothing solid on the cards, but that’s Ponta Do Rapa – it never stays good for long, and it rarely breaks at all. Keep your eyes peeled.
Rusty.
