The Lowdown
Alright, let’s get into it. Honestly, it’s been a flat spell for São Pedro, and the next 16 days aren’t offering much hope. We’re looking at a long stretch of tiny, clean waves and a lot of flat spells. There’s a big gap in the middle where there’s nothing at all, and then some small, long-period pulses show up late in the second week, but they’re just not big enough to surf.
From Wednesday the 9th through the weekend, it’s all about ankle-biters. Wednesday morning has a 30 km/h N wind, cross-off, but the swell is only 0.3 ft out of the west, with a combined energy of just 4. Thursday and Friday are completely flat. Saturday morning is glassy calm with a slight breeze from the NE, but again, no wave height. The water is 68°F, which is about 2°F cooler than normal, so nothing crazy.
We hit a real dead zone from the 11th to the 14th, with only the faintest 0.3 ft southerly pulses showing up. The energy is in the single digits. Sunday the 13th has a little cross-shore wind, but it’s still tiny. Monday the 14th is glassy in the morning, which is nice, but the swell is still just 0.3 ft.
Things get a bit more interesting around the 18th and 19th of September. We get a 0.3 ft swell from the southwest, but the period jumps to 15 seconds. That’s a very long period groundswell, and the energy is still weak, only 9. The wind is offshore on the morning of the 19th from the NNE at just 5 km/h, so it’s clean. But the break is a sheltered point, and it rarely breaks, so you’re really hoping that swell makes it in. It’s a tease, not a goer.
The very end of the window, around the 24th of September, shows a 0.3 ft south swell with a 15-second period and a combined energy of 10. The wind is light and glassy in the morning. It’s clean, but it’s still just a tiny pulse. The optimum swell direction for São Pedro is SW, so the SW swells in the second week are in the right ballpark, but the size is way too small.
There’s no standout session at all. The whole 16-day window is a washout. The combined swell energy never gets above 10, which is well below weak. For a point that rarely breaks, this is a pretty normal dry spell for the area. Keep the board in the car, but don’t expect much. Forecasts can change, but this one is looking pretty grim.

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.
