Porto Batel Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break down what Porto Batel is doing for the next couple of weeks.

The water’s at 69°, which is totally normal for this time of year – nothing weird going on.

The first few days are a bit of a grind. Tuesday morning starts with a 5ft NW swell, 9-second period, and the wave energy is moderate (334). The wind is cross-off from the north, so the faces are clean, but the surf is poor. The afternoon bumps up to 6ft from the NNW, more energy (449), but still poor. Wednesday and Thursday are the same pattern: clean wind, but the swell is a messy, short-period windswell, and the notes say marginal or just ordinary. By Friday morning, the swell drops to 2ft from the WNW, energy is weak (68), and it’s not worth getting wet.

The real action starts to build around the weekend of the 7th and 8th of September. On Saturday the 7th morning, we’ve got a 3ft NW groundswell with a long 12-second period, moderate energy (430), and clean conditions. It’s still marginal, but you can feel it turning. The afternoon of the 7th is better: 5ft NW, still 12 seconds, energy hits 543, and it’s clean. This is a real window.

Then Tuesday the 8th of September gets serious. Morning sees 6ft from the NNW, period drops to 7 seconds, but the energy is strong (561). The wind is still cross-off from the north, so it’s clean. The afternoon pushes 7ft from the NNW, 9 seconds, and energy hits 629. Still marginal in the notes, but that size on a point break with clean cross-off wind is a recipe for good waves. Because it’s a point, that longer-period groundswell will wrap in nicely. Just a heads-up: with swell over 5ft, beginners will be in over their heads.

The absolute standout is the 10th of September. Thursday morning brings 8ft from the NNW, period of 9 seconds, and the combined energy is a strong 926. The wind is a clean cross-off from the NNW at 25 km/h. This is big, powerful, and clean. At over 8ft, this is expert-only territory. Porto Batel is a point break, so it handles size well, but you need to be on your game. The afternoon is still pumping at 7ft, energy at 715.

After that, the swell fades towards the 11th and 12th, but there’s a final sweet spot on the 15th of September. Tuesday the 15th morning shows a 4ft NW swell, 9 seconds, with a light offshore breeze from the NE and energy of 360. That one is flagged as “expect good surf conditions,” the only positive call in the entire forecast. Light wind, clean waves, and a solid size for a fun session.

The best bet is the 10th of September for the big, powerful, clean lines – but only for the experts. The 15th of September is the pick for a more relaxed, quality session.

Keep your head on a swivel out there.
