The Lowdown
Alright, let’s switch it up for the imperial crew. Rusty here.
Right, so this Ponta Do Rapa forecast is a bit of a head-scratcher. It’s a spot that rarely breaks, so you’ve gotta be on it when it’s good. The water’s about 65°, pretty average for this time of year.
The first week is mostly a write-off. Sunday the 13th has a 5ft south swell with trashy cross-off winds. Monday the 14th is flat and messy. Not worth a look.
We get some small, crumbly stuff on the 15th and 16th, but it’s nothing to get excited about.
Thursday the 17th is your first real winner. The morning session has got it all. A clean 5ft south swell, long period at 11 seconds, and the wind is glassy. That’s a beautiful combination for a reef. The energy is solid at 543. The sets will have some power and shape. It’s advanced territory at this size, and since it’s a rare break, you’ll have it pretty much to yourself. This is the one to circle.
After that, Friday and Saturday the 18th and 19th are pretty poor. Small, weak swells are all we get.
Sunday the 20th morning is another chance. The wind is glassy again, which is a huge plus. The swell is 5ft from the east, but it’s a short period at 7 seconds, so don’t expect any grunt.
The start of the third week, Monday the 21st and Tuesday the 22nd, offers some more hope. Tuesday morning is looking clean and glassy with a 5ft east swell and a decent 9-second period. A nice mellow day for a paddle.
Now, we hit a massive lull. From Wednesday the 23rd through Saturday the 27th, forget it. It’s small, weak, and the wind is onshore.
But then, the grand finale. Monday the 29th of September is for experts only. The swell is a solid 7ft from the south with a very long 14-second period. The combined swell energy explodes to 1619 – that’s a serious amount of water moving. It’s a powerful, groundswell that will turn that reef into a beast. The wind isn’t perfect, but the power is undeniable. That’s not a beginner’s day.
Rusty.
