Praia do Porto Surf Forecast and Surf Report

Alright, let’s get into it. This is the one and only spot we’ve got on the radar right now, so I’ll take you through the whole 16-day run for Praia do Porto.

We’ve got a bit of a slow start here. The first decent window kicks off on Friday, September 11th in the afternoon. The water’s sitting at 62°F, which is 4°F colder than normal for this time of year – that’s a pretty noticeable chill, so you’ll want a good wetsuit. Swell is around 3ft from the ENE with a short 8-second period, and the combined wave energy is moderate at 222. Winds are light offshore from the WSW, so it’ll be clean, but the waves are just surfable – nothing to write home about.

Saturday the 12th is a step up. Morning brings 5ft of S swell, but with a short 6-second period, so it’s a bit junky. The wind is offshore from the SW, moderate, keeping things clean. The afternoon pushes to 6ft from the S, 8-second period, and energy jumps to 441 – moderate to strong. Wind swings cross-offshore though, so it’s not perfect, but it’s a solid session for a beginner-plus spot.

Sunday the 13th backs off a bit. Both sessions offer 4ft from the SE, with 8-second period. Light offshore winds in the morning, light in the afternoon. Energy is around 256-258. It’s clean, but very ordinary. A good day to work on technique.

Now, Monday the 14th – this is where it gets interesting. The morning is glassy with 4ft from the S, but the period stretches to 11 seconds, which is proper groundswell territory. Combined energy hits 510, that’s moderate to strong. The afternoon is even glassier with calm winds, 3ft from the S, same long period, energy at 453. These are clean, quality waves, but the long period means it might be a little straight at this beach/jetty setup. Best for the more experienced crew.

Tuesday the 15th delivers some punch. Morning has 6ft from the E, 8-second period, energy at 662 (strong). Light offshore winds. The afternoon drops to 5ft from the ENE, 9-second period, still strong at 614 but with cross-offshore winds. Good, but not as clean.

Wednesday the 16th – morning looks good with 5ft from the E, 9-second period, energy at 522, and gentle offshore wind. Afternoon gets messier with cross-offshore winds and smaller waves.

Thursday the 17th starts glassy with 4ft from the S, 8-second period, energy at 360 – clean. But the afternoon turns onshore and messy.

From Friday the 18th through to Sunday the 20th, it’s mostly poor. Onshore winds, choppy conditions, and onshore windswell. Not worth paddling out. Monday the 21st and Tuesday the 22nd see a return of glassy mornings and cleaner conditions, with swell around 3ft to 5ft and periods improving to 9-10 seconds – good for a quiet session.

Wednesday the 23rd and Thursday the 24th are small and weak, with energy dropping below 132 – barely worth the walk down.

But hold onto your board, because Friday the 25th is the standout. The morning is glassy with 8ft from the S, short 7-second period, energy at 576. Then the afternoon: 10ft from the S, 9-second period, and combined energy is a massive 1600 – that’s very strong. Winds are moderate offshore from the SSW, so it’ll be clean. This is for experts only – too big and powerful for the average surfer. If you’ve got the skills, this is the session of the forecast.

Saturday the 26th looks promising on paper with 7ft from the S, 12-second period (very long), energy at 1290, but the wind is onshore from the NNE, ruining it. The afternoon is even worse with 19 mph onshore wind. Skip it.

So, to sum it up: the best bet is Monday the 14th for clean, glassy, long-period groundswell – great for reef and point style surfing at this beach/jetty. The absolute standout is Friday the 25th afternoon for the big, powerful, offshore cleanup – but only if you’re an expert. Crowds are possible here sometimes, so expect company on the good days.
