Table - best surf conditions forecast for Praia do Porto over the next 16 days.
The Lowdown
Righto, let's take a look at Praia do Porto. The 16-day window has got some action, but you gotta pick your moments. The water temp is sitting at 62°, which is 4° colder than it should be for this time of year, so that's notably chilly – you’ll want a good steamer.
The first real chance for a wave comes Thursday the 10th. We’ve got a 3ft S swell with a clean 12-second period pushing in. The combined energy is moderate, sitting at 551, and with glassy conditions first thing, that’s your go. It’s only a beginner-plus spot, so this is ideal for getting a few clean ones without the crowd if you’re early.
Friday the 11th is a write-off. That NE wind and short-period chop will turn it into a mess. Saturday the 12th is where it gets interesting. A solid 8ft S swell rolls in, and the wind goes offshore from the SW early – 15 mph offshore makes for clean, lined-up waves. The combined energy jumps to 892, which is strong. That’s the standout session for the week. It’s a bit much for beginners, though; this is more for the crew who know what they’re doing.
Sunday the 13th has some leftover energy at 5ft from the SSE, and glassy winds in the morning will clean it up nicely. Good surf. Monday the 14th gets messy with onshore wind, so give it a miss. Tuesday the 15th is another clear winner with an early offshore wind on a 6ft E swell, offering clean conditions. The energy is still solid at 696.
The following week sees a drop-off. Wednesday the 16th has a clean 4ft SSW swell with offshore wind, but it’s small. From Thursday the 17th through to the 20th, the wind is mostly rubbish, onshore or cross-on, and the swell is either short-period or blown out. By Saturday the 19th there’s a glassy morning with a 3ft SSE long-period swell (14 seconds), but it’s tiny and the crowd factor is listed as “sometimes,” so you might have it to yourself if you’re desperate for a paddle.
Heading into the 22nd and 23rd, the wave energy drops right off – we’re talking combined energy of 74 to 77 – so it’s flat and not worth the wet suit struggle. The 24th has a tiny 1ft ESE swell with a long 12-second period and offshore wind, but it’s barely a ripple.
Overall, the top pick is Saturday the 12th for the biggest, cleanest swell of the run. If that’s too heavy, Saturday the 15th morning is your next best bet for quality. After that, it fades into a long quiet spell.

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.
