The Lowdown

Alright, let’s get into it. The next couple of weeks are a bit of a mixed bag, so you gotta pick your moments around here. The surf is going to come and go, so be ready to move when it’s good.

We start off with a bit of a lull in the action for a few days. Tuesday through Friday of this week are pretty poor. There’s swell, around the 4ft to 5ft mark, but it’s coming in with cross-onshore winds, and the energy is just weak, sitting around 342 to 552 units. It’s not worth the paddle. Thursday afternoon has a longer period, but it’s onshore and messy. Just leave the board in the car for a few days.

The first real sign of life shows up Saturday morning. The wind swings offshore out of the southwest, and the swell jumps to 8ft with a solid push of energy (1072). It’s a bit raw and still questionable on the tide, but that’s the first sign of things turning on. Sunday is where it starts to get fun. The swell drops slightly to around 7ft to 7ft, but the wind is light, the conditions are clean, and the energy is strong (746 to 1255). This is a good window.

Then we get a reality check on Monday. The wind turns back onshore, and it’s choppy and messy. Not good.

But hold on, because Tuesday of the following week is the standout. That morning, you’re looking at 10ft of swell with a massive surge of energy (2751), and it’s offshore. This is serious size, so it’s only for the experienced crew. It’s going to be powerful. The afternoon stays big but the wind gets a bit more cross-off, so the morning is your best bet for clean, big waves. That’s the one to circle on the calendar.

After that, things ease off a bit into Wednesday, with the swell dropping to 5ft but still clean and fun. The rest of that week into the weekend (17th-19th) looks poor again, with onshore winds and weak, short-period swell. It gets pretty small.

There’s another pulse of big swell on the 20th, around 10ft from the northeast. It’s onshore in the morning, but the afternoon cleans up nicely with a cross-off breeze and 2404 units of energy. That’s another good one for the experienced crowd.

The final stretch, on the 21st and into the 22nd, is really nice. We’ve got solid swell, 6ft to 8ft, with clean offshore winds. The 22nd is glassy with a long, powerful period (13-14 seconds), which will groom everything out. That’s looking excellent for the experts.

For the standout pick, I’d have to say the morning surf on the 15th is your best bet for raw power, and the afternoon of the 20th for the more manageable big-wave session. The 22nd is also a gem, but it’s further out, so keep an eye on it.

The water temp out at Praia do Porto is 64°F, which is about what you’d expect for this time of year.

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. Our Praia do Porto surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Praia do Porto) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
