The Lowdown
G’day, Rusty here. Lookin’ out at the 16-day window for Sao Pedro, and mate, I gotta be straight with you – it’s a tough one. This spot is a sheltered point that rarely breaks, and through the whole forecast period, the swell is just not showing up. There’s a long stretch of flat, weak conditions with nothing to get excited about.
We start off with a few days of tiny, almost non-existent surf. From Friday 14 August through Tuesday 18 August, the wave heights are stuck at 0.3 ft, sometimes 1.0 ft, with the combined energy barely registering, mostly between 3 and 40 (weak). The swell direction is hanging out of the SW, with a period that’s long (12 to 18 seconds), but there’s just no size to push it. The water temp is about 70°F, which is pretty normal for the time of year, so nothin’ weird there.
Even the best-lookin’ spell – Sunday 16 August morning with glassy conditions and a NE wind at 3 mph – still has only 0.3 ft of SW swell. It’s clean, but there’s nothin’ to ride. By Wednesday 19 August and Thursday 20 August, it’s still flat, with some days showin’ zero energy. The wind goes variable, with some offshore spells on Monday 24 August and Tuesday 25 August, but the swell is laughable – 0.3 ft to 1.0 ft at best.
The second week is a write-off. From 23 August onward, it’s all 0.3 ft or 0.7 ft, with energies from 2 to 40 (weak). The swell direction stays SW, but the period drops to 7 to 14 seconds, still no punch. Saturday 29 August shows flat lines with no height or period at all. There’s no standout, no proper wave to paddle into. For a rare-breaking point like this, a blank run is more normal for the area, but it’s still a bummer. If you’re a kiter, the consistent cross-off winds might be somethin’ else, but for paddle surfing, it’s a no-go.
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.
