The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up for Porto Batel over the next couple of weeks.
Honestly, for the first few days, it’s a bit of a write-off. We’ve got wind and swell out of sync, and the water is a bit colder than you’d expect for this time of year, with temps sitting at 67°F and an anomaly of 2°F below normal. The best we can say is to sit tight.
The first real chance to get the board wet comes on Thursday, 20 August. The morning is looking workable, with a clean surface and a tiny 2ft swell from the WNW. The combined energy is weak, barely hitting 75, so it’s a longboard-only kind of day. The wind is light and cross-off, which is a blessing, but don’t expect much push.
Things get a bit more interesting heading into the second week. The standout window is shaping up around Friday, 21 August through Sunday, 23 August. The swell jumps up, hitting 7ft to 10ft from the NNW, with corresponding period around 8 seconds. The energy ramps up significantly, with readings in the 1000s range on the 21st and 23rd, so there’s some serious power behind it. The wind stays consistently cross-off from the N or NNW, keeping the face clean. This is for the confident intermediate crew – anything over 8ft is getting into expert territory only. The wave quality is labelled as marginal, but with that clean wind and a proper swell, Porto Batel’s point setup should offer some decent lines.
Later in the window, Thursday, 27 August could be a sneaky good one. The swell drops back to a more manageable 5ft to 6ft, still from the NW, but the period stretches out to 10 seconds. That’s groundswell, meaning more energy and better shape. The energy is moderate to strong, around 413 to 590. The morning is a bit cross, but the afternoon cleans up with a moderate cross-off. It’s a solid option for a late-summer session.
The very end of the forecast, on Monday, 31 August, don’t sleep on the morning. It’s tiny, just 2ft, but the wind is glassy, and it’s clean as a whistle. Perfect for a zero-stress, longboard cruise.
So, if you’re after the best bang for your buck, point your car at Porto Batel for the weekend of the 21st to 23rd. The swell is on, the wind is right, and it’s just a matter of picking your size. The 27th of August is a solid backup if you want something with a bit more period and less crowd pressure.
Rusty.

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. If you surf the same spot (Porto Batel) 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 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.
