The Lowdown
G’day, Rusty here. Let’s break down what’s on the cards for Praia do Porto.
Right now it’s pretty average. Sunday morning you’ve got swell around 4ft from the ENE, short 7-second period, and the combined energy is weak at 185. Wind is offshore from the SSW, so it’s clean, but the waves are small and weak. Sunday afternoon is similar with 4ft and a bit more period at 8 seconds, but nothing to get excited about.
Monday is a dud with onshore wind and poor conditions. Tuesday morning, 4th August, things start looking up. Wind goes glassy, swell drops to 3ft but shifts to the south with a 12-second period, so the energy jumps to moderate (461). Expect clean, glassy lines. Tuesday afternoon is even better with the same glassy wind and 4ft south swell, energy up to 534. That’s your first real window – small but clean.
Wednesday morning is still surfable with 3ft from the SSE and offshore wind, but the energy is moderate (202). Then it goes quiet again through Thursday and Friday with small, choppy conditions and poor quality.
The standout is Sunday, 9th August. The swell pumps up to 10ft from the south, 9 seconds, and the combined energy is 2349 – that’s strong. Wind is cross-offshore from the SSW, so it’ll be clean. This is proper, solid wave energy for experienced surfers. Sunday afternoon is still excellent with 8ft and 11-second period, energy at 1316.
Monday 10th looks big again – 10ft south swell, 13-second period, and energy hits 5961, very strong. But the wind is onshore, so it’s messy and only for the brave. Tuesday 11th is a gem: 7ft south swell, 13–14-second period, with offshore wind from the SW and energy around 1346–1460. Clean, powerful, and well-shaped. That’s a top pick.
Wednesday 12th keeps the good run with 6–5ft south swell, 12–13 seconds, light offshore wind, and energy dropping to moderate-high (1055–749). Thursday 13th sees the wind turn onshore again, and the surf quality fades.
The water temperature is 67°, which is a touch warmer than normal for this time of year.
Best bet: Tuesday 11th August morning or afternoon – clean, offshore, solid 7ft south swell, great energy. If you’re an experienced surfer, Sunday 9th morning is also a standout for size.

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.
