The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening in the water. I’ve been staring at the charts and, honest to god, it’s a tough stretch for us. We’re looking at a long, quiet run with hardly any wave energy to get excited about. The one spot we’ve got, Sao Pedro, is a point break that’s sheltered, but it rarely breaks, so conditions have to be perfect. And perfect they are not.
For the first few days, it’s all messy. Sunday the 23rd brings a weak 3ft SW swell, but it’s riddled with a 22 mph cross-on wind that’s just tearing it up. The combined energy is a low 93, so there’s no punch. Monday the 24th sees a jump in size to 8ft from the WSW, but that’s still blown out by 19 mph onshore winds, making it a lumpy, choppy mess. The energy climbs to 758 (moderate), but it’s ugly. Skip it.
Then we hit a dead zone. From Tuesday the 25th morning, the swell just collapses. You’ve got tiny 0.3ft to 0.7ft waves, often no swell at all, and the combined energy drops to single digits or zero. We’re talking about a gap that lasts from the 25th of August all the way through to the 7th of September. That’s nearly two weeks of flat or near-flat conditions. The wind does turn offshore or cross-offshore from the 28th onward, which keeps the water glassy and clean, but there’s just nothing to push the waves. Even a 16-second period groundswell pops up on the 31st of August, but at 0.3ft, it’s a ghost.
The best of a bad lot? Honestly, there’s nothing that lights up the board. But if you’re desperate, the morning of the 4th of September has a tiny 0.7ft SSW swell, with a gentle 9 mph cross-offshore wind. The water temp is about 68°F and that’s about 2°F cooler than average for this time of year, so it’s not unusual. But the energy is only 17 (weak). It’s a paddle float, not a surf session. For a spot that rarely breaks, this is a blank run that’s pretty normal for the area.
Signing off, Rusty.

Information about the Sao Pedro Surf forecast
The above surf forecast table for Sao Pedro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sao Pedro can be found by selecting the local surf guide option on the grey menu. Our Sao Pedro 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 (Sao Pedro) 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 Sao Pedro 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.
Sao Pedro is 2 km (1 miles) from Parede. If you plan a holiday in Lisboa, look for hotels and other accommodation in Parede. Parede has rooms for a wide range of budgets as well as car hire and transport links.
