The Lowdown
Alright, let me level with you. For a spot that rarely breaks and needs everything to line up just right, the next couple of weeks are looking pretty grim.
Gazing out over the whole 16-day window from now, I’ve got to be straight with you – there ain’t a single day worth paddling out. The first few days of the outlook show flat to almost flat conditions. On the 20th of August, we’re looking at a tiny 1 ft swell, but the period is a short 4 seconds, so there’s no grunt behind it. It’s glassy that morning, but with only 4 units of combined energy, it’s just not enough to wrap around the point.
The long-range into the end of August and early September isn’t any kinder. We are staring down a significant gap with zero surf on offer for days at a stretch. From around the 28th of August, the swell completely flatlines, and even with clean, offshore winds, you can’t surf what isn’t there. The one small blip at the very end, on the 31st of August, shows a super long period 19-second groundswell, which normally gets the heart racing, but it’s only 0.3 ft. That’s just a long-period bump on a lake, not a wave. Combined energy (19) confirms it’s weak as dishwater.
Water temp is sitting at 68°F, which is pretty much normal for this time of year, so at least you won’t be freezing on the beach watching the flat spell.
Honestly, for this region, a blank run like this isn’t that unusual. Sao Pedro is a sheltered point that rarely breaks, and this forecast is the textbook example of why. If you've got a kite, those cross-off winds from the NNW from the 21st onward are blowing 15 to 28 mph, and the setup is a beach and point – that could be more interesting for you than a surfboard right now. But for the rest of us? It’s a waiting game. It tends not to stay this poor forever, and forecasts can change, but right now, there’s nothing to get excited about.

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.
