The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer at Praia do Porto over the next couple of weeks.
Straight up, it’s a slow start. The first week or so is pretty ordinary, with only small, messy waves and iffy winds. There’s a real gap from now until the 4th of August where the surf is just not worth paddling out for. But then things start to look up, and the second half of the window has some proper promise.
The standout window kicks off on the morning of Tuesday, the 4th of August. The swell bumps up to 4ft from the S, with a period of 11 seconds, giving it some decent juice. The combined wave energy is a solid 576 (moderate energy), and the wind is glassy – that’s the dream. That morning session is going to be clean, lined up, and surfable. The afternoon keeps it going with a gentle offshore wind from the SSW (6 mph), keeping the waves tidy. Praia do Porto is a beach/jetty setup, fairly exposed to the S swell, so this will be the pick of the whole outlook.
The next morning, Wednesday the 5th of August, is also a winner. The swell drops to 3ft from the SSE, but the period is 10 seconds and the wind is glassy again. Combined energy is 269 (moderate), so it’s not as powerful, but it’s clean and fun for a longer board or a cruisy session.
Later in the run, from Sunday the 9th through Tuesday the 11th, we get another consistent stretch. On the 9th, the swell is 4ft from the ENE with a short period, but the wind is a solid offshore from the SSW (12-13 mph), giving clean, punchy waves. The combined energy is strong (421-460). Then Monday the 10th morning is glassy with 4ft S swell and a 11-second period (545 energy), which is a real highlight. Tuesday the 11th keeps the offshore wind and clean lines with 4ft SSE swell.
The water temp is about average for the time of year, nothing unusual, so a spring suit will do.
Don’t get too excited about the early days; the 28th to the 3rd of August is mostly onshore, choppy, or just too small. By the 4th, though, it’s game on.
Rusty.

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.
