The Lowdown

Alright crew, Rusty here. Let’s have a look at what’s shaping up for Ponta Do Rapa over the next couple of weeks.

Straight off the bat, the first few days are a bit of a write-off. Thursday the 10th and Friday the 11th are a no-go with messy, cross-onshore winds and weak, short-period swell. You’re better off staying home or getting the gear ready for later.

Things start to turn around on Saturday the 12th. We’ve got a solid S swell pushing 7 ft to 8 ft, with a period of 8 to 9 seconds, and the wind goes clean cross-off. The combined energy jumps right up (653 to 870), which is moderate to strong. This is a beefy swell, so it’s for the experienced crew only – over 8 ft territory for the experts. The water temp is sitting at 66°, which is about average for this time of year, nothing unusual.

Sunday the 13th brings a cleaner vibe. The swell drops to 4 ft to 5 ft from the SE, period around 8 seconds, and the wind is light cross-off turning to a gentle offshore in the afternoon. The energy is a solid 384 (moderate). This is a proper surfable day, clean and lined up. Good for a wide range of surfers.

Monday the 14th is a standout. The ESE wind is a moderate offshore all day, pushing a 7 ft E swell (7-second period) in the morning, dropping to 6 ft in the afternoon. Energy is strong at 725. This is the best combination of size and wind we’ve seen. Clean, offshore, and punchy. If you’re intermediate or above, this is your window.

But the absolute pick of the forecast is Tuesday the 15th. Morning glass-off conditions – dead calm, glassy surface – with a 6 ft E swell (8 seconds). The energy is still high (782). That’s as good as it gets here. Clean, lined up, and no wind to mess it up. It’s a gem. The afternoon turns a bit lumpy with a cross-off breeze, so get on it early.

From Wednesday the 16th onwards, things fade. The swell drops off, and the wind becomes a bit of a factor. There’s a brief window on Thursday the 17th with a 4 ft S groundswell (12-second period) and clean cross-off winds, but the energy is moderate (586). This is a long-period swell, which can be a bit straight at a reef setup, but it’ll still offer some nice, fat waves with long waits between sets.

After that, it’s mostly poor surf with messy wind until the 24th and 25th, where tiny, weak swell (1 ft to 5 ft) and dirty conditions take over. The 24th has a long-period 12-second ESE swell, but it’s only 1 ft – barely surfable.

So, to sum it up: the first few days are a dud, then from Saturday 12th to Tuesday 15th is your prime window. Tuesday 15th morning is the best on offer – glassy, clean, and solid. Get out there.

Rusty.
