Alright, Rusty here. Let’s talk Praia do Porto in feet, Celsius, and miles per hour.
It’s a slow start, but there’s a couple solid sessions to chase if you time it right.
Tuesday morning, July 7th, we get a brief pulse – 5ft S swell with a clean offshore breeze. Period’s short at 8 seconds, so it’s a bit weak with combined energy around 521. Nothing special, just enough for a beginner lap. It fades quick, and Wednesday is all blown out.
Thursday to Friday the 10th is flat and small, mostly 3ft to 4ft. The first real go is Friday afternoon: 4ft ESE swell with a 12-second period, light cross-off wind, energy of 529. For a proper session, that’s the first target.
Saturday the 11th is cloudy with a light cross-on breeze, but the swell’s 4ft to 5ft with a long 13-second period and energy up to 674. Not perfect, but there are waves.
The big standout is Sunday the 12th. Morning is clean offshore with 3ft ESE swell, 12 seconds, and 676 energy. Afternoon is where it’s at: 6ft S swell, short 7-second period but clean cross-off and energy of 782. That’s the best of the whole run – punchy, powerful, and fun. Too big for beginners, but great for the rest of us.
Monday morning the 13th brings 6ft S swell (energy 834) with clean offshore wind – the biggest, most powerful swell of the outlook. Crowds can be a thing here, so get in early. Afternoon gets messy.
Tuesday the 14th morning is glassy with 4ft SE swell and 11 seconds – a rare clean treat. Afternoon gets blown out.
From Wednesday the 15th onward, it’s mostly poor. A couple glassy mornings on the 16th and 17th with small swell (3ft, 8-11 seconds, weak energy of 150-279). Bigger swells hit from the 18th – 6ft E swell and 1075 energy – but accompanied by strong onshore winds and chop. That’s kite-surfing conditions, not for paddlers. The run from the 18th to the 22nd is basically a write-off for us.
Best bets: Friday afternoon the 10th, Sunday the 12th, and a glassy bonus on Tuesday morning the 14th. After that, it’s time to wait for the next swell.
Rusty.

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.
