The Lowdown
Alright folks, Rusty here. Let's get straight into it for this local stretch. I've got to be straight with you – this 16-day window is a tough one. We're looking at a real dry spell, so grab a coffee and listen up.
Right off the bat, for the rest of August and into the first days of September, there's simply nothing doing. The first recommendation doesn't pop up until the very end of the outlook, so we've got a long gap of nearly two weeks with no worthwhile waves on offer. The combined swell energy barely gets out of single digits, and most of the time it's sitting at zero. It's one of those blank runs that's more normal for this area, unfortunately.
Now, if you squint at the very end of the forecast period, things get a tiny bit interesting. On Monday the 31st of August, there is a faint pulse. The swell is tiny at only 0.3 ft and coming from the south (S) with a very long period of 14 seconds. That long-period groundswell energy is a positive sign for a better shaped wave, but the combined energy is weak at just 8. The morning looks best with a light northwesterly wind that cleans things up. São Pedro is a sheltered point break that rarely breaks, so this is a notable event. For a spot that rarely sees surf, even a small clean wave might offer a few fun, gentle ones for a beginner, but don't expect much more than a knee-high dribble.
Honestly, that Monday morning is the only standout, and even then it's a faint one. The rest of the window is a write-off for a paddle. With the persistent onshore and cross-onshore winds, and the flat spells, this setup looks far more interesting for kite surfing than for paddle surfing. Stay tuned, it tends not to stay this poor for long and forecasts can change.
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.
