The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for Praia do Porto. It’s a bit of a mixed bag over the next couple of weeks, but there are a couple of windows that’ll get your heart pumping if you time it right. Let’s break it down.
We start off a bit flat and ordinary. Thursday the 30th through the weekend has some small waves, but the winds are messy. Thursday morning has a small 2ft south swell with a 9-second period and a light cross-offshore breeze, giving us clean but very ordinary waves. The combined energy is weak (107). The afternoon turns cross-on, and it gets worse. Friday and Saturday are a write-off with strong onshore winds and poor conditions. Sunday the 2nd shows a little pulse, with a 4ft swell from the ENE and a clean offshore wind in the morning, but it’s still pretty average.
Monday the 3rd is more of the same. Then comes a real glimmer of hope. Tuesday the 4th, the wind goes glassy in the morning with a 4ft south swell (11-second period, 390 energy). That’s a clean, fun-sized wave. Wednesday the 5th keeps the good vibes going with a 4ft south swell (10-second period, 411 energy) and clean offshore winds in the morning. This is a solid run of small but quality surf.
Then the conditions get sloppy again through the end of the first week and into the second. The real standout, and I mean the *big* one, is on the 11th and 12th of August. A massive groundswell arrives. On Tuesday the 11th, the morning swell is 12ft from the SSE with a 14-second period and a cross-onshore wind – that’s way too big and messy, basically a kite surfer’s dream. But the afternoon is a different story. It drops to 8ft from the SSE, with a 16-second period and a clean cross-offshore breeze. The combined energy is a massive 3918. This is expert territory – well overhead, powerful, and long period. It’s a serious wave for experienced surfers only.
Wednesday the 12th of August stays excellent. The morning is glassy with a 7ft SSE swell (13-second period, 1832 energy). The afternoon is clean with a 6ft swell. If you’re a competent surfer, this is the best window of the whole forecast. The water temp is about average for the time of year, nothing unusual to report.
The swell fades out after that, with Thursday the 13th and Friday the 14th looking poor again due to strong onshore winds.
For a beginner, the best bet is those small, clean days around the 4th and 5th of August. For the experienced crew, lock in the 11th and 12th of August – that’s the real deal.

Information about the Praia do Porto Surf forecast
The above surf forecast table for Praia do Porto provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Porto can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia do Porto may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
