The Lowdown
Righteo, let's get into it. This is Ponta Do Rapa, and it's a tricky one. The forecast is a bit of a mixed bag, but we've got a few windows where it could come together. Before we get into the good stuff, I gotta say, the water is sitting at 61° right now, which is a full 5° colder than usual for this time of year. That's not just a nip in the air, that's a proper bite, so you'll be wanting a good thick wetsuit.
Right now, the swell is around but it's a messy, short-period 5ft from the ENE, with a cross-shore wind. The energy is weak (347) and the conditions are poor. Not a great start. We're going to see a few days like this, with the swell bouncing between 5ft and 7ft, but the wind is just never on our side. It's mostly cross or cross-on, and the comments are all "poor" or "marginal." We've got a few days of this until we get a bit of a break.
Now, the first real standout looks to be Tuesday the 21st of July. The morning is looking glassy, with zero wind. The swell drops a touch to 5ft from the ENE, still with that short 8-second period, but with clean conditions, it'll be a lot more fun. The energy is still low (295), so don't expect bombs, but it'll be a rewarding session if you pick your waves. The afternoon holds too, with a light offshore breeze from the SE and waves at 4ft. That's a good day's surfing.
We get a couple of days of onshore junk after that, but then Thursday the 24th of July afternoon looks promising. The swell swings around to the SSE with a longer 10-second period, and a clean cross-offshore breeze from the NE. The swell is 5ft, but the energy is moderate (454). This is a better quality wave, and the wind is right.
The following week is a real mixed bag. The swell hangs around, but the wind is all over the place. There's a moment on Sunday the 26th of July where the swell is from the S with a 12-second period, but it's blown out by a strong cross-offshore wind. The best bet in the second week is likely Monday the 27th of July morning. The swell is small at 3ft, but it's a clean, glassy south swell with a long 11-second period. The energy is weak (293), but it's an option for a quiet, clean session if you're desperate.
Beyond that, it's a bit of a gamble. The swell picks up again on the 29th, but the conditions are marginal. Look, Ponta Do Rapa is a rare-break kind of spot, and this forecast reflects that. It's not a spot you can just rock up to and expect perfection. But if you can time it for that Tuesday the 21st, you might snag a few clean ones.
