The Lowdown
Alright, let me tell you what I'm seeing for Praia do Porto. This is a beach and jetty setup, fairly exposed to the swell, and the best direction for the waves is from the southeast. The water temp is sitting around 66°, which is about normal for the time of year.
There are a few decent windows coming up, but honestly, the first stand-out is that Tuesday morning, the 28th of July. We’ve got a 5ft swell from the north-northeast, and the wind is coming from the southwest, giving us a clean offshore breeze. The combined swell energy is moderate at 307, so there’s some punch. With that offshore wind, it’ll be clean, which is a major positive.
Later that same week, Thursday afternoon the 30th is another good call. A 5ft swell from the south, with a light cross-offshore wind from the south keeping things tidy, and moderate energy at 341. Clean again.
The real standout, and this is the one to pencil in, is the morning of Sunday the 9th of August. We’re looking at a solid 6ft swell from the south, and here’s the kicker: glassy conditions with no wind. That's a rare treat. The combined energy is strong at 865. That’s the best looking window in the whole run, but it’s a couple weeks out, so treat it as promising but not locked in. Keep an eye on it.
The rest of the time, it’s a bit of a mixed bag. There are a few mornings with glassy conditions and small waves, like Monday morning the 27th with a 2ft south swell and glassy winds – that’s a surfable wave but very ordinary. There are also some bigger swells in early August, around the 4th to the 8th, with 7ft to 8ft waves, but the wind is howling onshore from the north-northeast at 12 to 19 mph, making a mess of things. That’s not for me.
So, for the best surf, get on that Tuesday morning, the 28th of July, or the Thursday afternoon, the 30th of July. The real prize is the 9th of August morning if the forecast holds.

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.
