The Lowdown
Alright folks, Rusty here. Let’s have a look at what Porto Batel has got cooking for us over the next couple of weeks. It’s gonna be a slow burner, so don’t expect perfection overnight.
The first few days are flat and pretty grim. Tuesday the 18th and Wednesday the 19th are write-offs with onshore slop and barely any energy. Thursday the 20th is tiny and glassy in the morning, but there's just no size—only 1.6ft from the WNW. We’re going through a quiet patch right up until Friday the 21st.
Now, Friday the 21st morning is where things finally start to get interesting. We’ve got a solid NNW swell pushing 5.6ft, with a period of 7 seconds, and the wind is a clean cross-off from the north at 18.6 mph. Combined wave energy is ramping up to a moderate 540. The waves will be a bit short-period, so a little crumbly, but that offshore flow will keep the faces tidy. This is your first real chance to paddle out.
Saturday the 22nd and Sunday the 23rd see that NNW swell holding strong. Saturday morning is 6.6ft with the same clean cross-off wind, and the energy is strong at 806. It’s pushing expert territory by Sunday morning though, hitting 8.2ft with 21.7 mph cross-off winds (908 combined energy). This is big, raw, and only for the experienced crew. The swell direction matches the optimum W for the point, so it should line up nicely at Porto Batel itself.
By Monday the 24th, the swell drops back to a more manageable 6.6ft, still clean, and the energy is at 458. It’s still decent, but the standout window is definitely Saturday the 22nd. That morning offers the best combo of size, clean conditions, and moderate crowd potential—just be aware it can get a bit busy here sometimes.
After that, we fade out through the rest of the week into tiny stuff, with a few marginal pulses around the 27th and 28th, but nothing to get excited about. The very end of the run, on the 30th and 31st of August, sees another spike to 8.2ft, but with onshore winds and messy conditions—keep an eye on that one, but it’s a long way off and uncertain.
Overall, if you’re looking to score, your best bet is Saturday the 22nd morning at Porto Batel. That’s the pick of the period.

Information about the Porto Batel Surf forecast
The above surf forecast table for Porto Batel provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Porto Batel can be found by selecting the local surf guide option on the grey menu. Our Porto Batel 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.

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 Porto Batel 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.
