The Lowdown
Alright folks, Rusty here. Let’s break down the surf ahead for this spot. It’s a bit of a mixed bag with a real standout window if you’ve got the skill.
The first few days are just okay. Monday afternoon the 10th kicks off with 7ft surf from the south, but it’s a bit messy with a cross-offshore wind. The energy is solid though – you can feel it in the water (1302). Water temp is sitting at 66°, which is bang on average for this time of year, so no surprises there.
Things get much better come Tuesday morning the 11th. The swell drops a touch to 6ft, still from the south, but the wind goes light and the waves clean up. Tuesday afternoon is even better – glassy conditions with 5ft south swell and that same long period (12 seconds) giving nice shape. This is a good run right through to Friday morning the 14th, with glassy or light offshore winds and consistent 5ft south-southeast swell. The energy stays moderate to strong (760-1003 range). The wave quality is there, but you’ve got to be aware that Ponta Do Rapa rarely breaks and is a proper advanced reef. It’s not for the faint-hearted.
The real highlight, without a doubt, is the window on Monday the 25th. Tuesday morning the 25th brings 5ft south swell, 12-second period, and light cross-offshore winds. But the afternoon is where it’s at – glassy, 6ft south-southeast swell with a 14-second period. That’s proper groundswell, and the combined energy jumps to 1581. This is excellent surf for experienced surfers. The long period means it’ll be powerful and walled-up on the reef, so you’ll want to be on your game. Crowds are only sometimes an issue here, so you might get a few out, but it’s worth it.
Expect a flat spell from the 15th through the 24th with mostly small, weak, and wind-affected waves. The swell drops to under 3ft, and the period gets short. There’s a brief bump on the 24th with 7ft south swell, but the wind is a fresh 30 km/h cross-offshore, making it too messy for a good paddle. It’s more of a kite-surfing setup that day.
Overall, the best bet is to wait for that Tuesday the 25th. It’s the clear standout. The rest of the window is a waiting game.
Rusty.
