The Lowdown

Alright, let’s get into it for Praia do Porto. The next few days are pretty flat and ugly – Monday afternoon and Tuesday morning have some tiny, weak windswell with onshore breezes that’ll just mess it up. Tuesday morning is glassy, but the swell is only 3ft from the south with a 12-second period – not enough to get excited about. Through Thursday, it’s basically a no-go. Don’t even bother looking at it until Friday.

Friday, August 7th is where it starts to wake up. Friday morning we get a clean offshore wind from the SW, and the swell is around 4ft from the ENE. It’s short-period, so not much power, but it’s rideable. Then Friday afternoon – that’s the first real session to circle: 5ft from the SSW, clean with a cross-off breeze, and the energy is 478 (moderate wave energy). Solid for a Friday arvo session.

Now, the real standout is the weekend of August 8th and 9th. Saturday morning (August 8th) delivers a big groundswell – 6ft from the south with a super long 15-second period. The energy reads 1637 (strong wave energy). That’s some serious push. It’s a little onshore, but the quality is there. That’s expert territory – beginners stay out. Then Sunday morning (August 9th) is the absolute gem: 4ft south swell, 13-second period, with a light offshore from the SW. Gentle offshore and clean – that’s as good as it gets. The energy is 739 (moderate to strong). For me, that Sunday morning is the pick of the whole 16 days. The beach/jetty setup here will handle that long-period south swell nicely, but keep an eye on the sets – they’ll have gaps.

Into the second week, the south swell keeps rolling. Monday the 10th and Tuesday the 11th are both looking clean and fun – 4ft to 6ft, offshore breezes, and glassy conditions on Tuesday afternoon. That Tuesday afternoon (August 11th) is another standout: 6ft south swell, glassy, energy at 797 – that’s a dream session.

We hit a rough patch Wednesday the 12th with strong onshore winds ruining things, then Thursday the 13th is small but clean. Friday the 14th brings another big pulse – 7ft south swell, clean, energy at 1262 (strong). That’s for experts only. After that, it fades out through the weekend with onshores and smaller surf.

Crowds are “sometimes” a thing here, so for the standout Sunday and Tuesday sessions, expect a few other surfers in the water.

Water temp is a touch warmer than normal at about 68°F, so you’ll be fine in a spring suit.

Bottom line: Sunday, August 9th morning is the one to plan for, with Tuesday, August 11th afternoon a close second. Friday the 7th afternoon is the warm-up act.

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.
