The Lowdown

Alright, listen up. Praia do Porto has a slow start, a proper fun pulse of energy in the middle, and then it fades out into small, clean conditions. I'm only talking about the days that are actually worth your time.

We're looking at a quiet opening stretch. Through this weekend and the start of next week, the swell is onshore, messy, and junky. You've got waves in the 4.6ft to 7.2ft range on Saturday, but the wind is blowing straight onshore and it's going to be a battle. Not worth it. That poor run continues through Monday and Tuesday morning, with the swell staying in the 6.9ft to 7.2ft zone and the wind still a problem. You're better off waiting.

The first real glimmer of hope comes late on Tuesday afternoon, the 18th. The wind swings around to a light cross-offshore, the surf cleans up, and we've got a clean 5.9ft of swell with a moderate wave energy of 467 in the water. It's still pretty ordinary overall, but it's the first sign we're getting out of the funk.

Then things start to build. Wednesday and Thursday stay small and a bit average, but Friday the 22nd is where it starts to get interesting. The morning is a clean 4.6ft with light offshore winds. But the real standout is Saturday afternoon, the 23rd. The swell jumps to a clean 6.2ft, the period stretches out to 11 seconds, and the combined energy is a solid 1540. The wind is a light cross-offshore, and the water is clean. This is the best-looking surf we've had all trip. It's got some push to it, so it's more for the experienced crew, but it's proper.

And it doesn't stop there. Sunday the 24th is a monster morning. We're looking at a powerful 7.9ft of south swell with a 12-second period and a massive energy reading of 1792. The wind is light and offshore. This is the biggest, cleanest swell of the whole window. It's a serious day, well over the 8.2ft mark for the experts on Monday, with a groundswell of 8.2ft at 14 seconds. That's a lot of water moving, and it's a proper standout.

By Monday afternoon, the 25th, it's still excellent for experienced surfers with a clean 7.5ft. The wind stays light, and the energy is still up there at 1874. Tuesday the 26th is a good one to finish on: a clean 5.2ft with almost no wind, glassy conditions. It's a bit smaller, but after that big pulse, it's a nice way to finish the run.

For the week that follows, things get smaller and less reliable. The energy drops off. It's not a blank run, but it's not the same quality. You might find a clean, glassy 3.0ft morning on the 29th, but the swell is short-period and weak. It's a case of getting out there for a fun, small wave if you're keen, but don't get your hopes up for anything epic.

So, bottom line: that Saturday afternoon the 23rd through Tuesday morning the 26th is where it's at. That's your window. The swell is solid, the winds are favorable, and the water is clean.

That's it from me. Stay stoked.

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.
