The Lowdown
Right then, mate, let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, it’s a bit of a flat spell we’ve got on our hands. For the entire 16-day window, the wave energy barely gets a pulse, and every single session comes back as poor surf. There’s a real gap here – from Saturday the 15th right through to Sunday the 30th of August, we’re talkin’ tiny dribbles and zero energy.
The one break we’ve got to go on is Sao Pedro (São Pedro). It’s a sheltered point break, best with a SW swell, but it rarely breaks, so this kind of run isn’t too unusual for the area. The water temp is sittin’ around 69°, which is about average for the time of year, nothin’ strange there.
On Sunday the 16th, we get a morning of glassy conditions – a NE breeze at 3 mph – but with only 0.3 ft of swell and combined energy at a measly 10, you’d be bobbin’ around on nothin’. That’s the cleanest the surface gets, but there’s no wave to surf.
There’s a tiny bump on Tuesday the 18th afternoon, the biggest of the lot, with 1.0 ft of SW swell and combined energy reachin’ 48. It’s onshore wind though, so it’ll be messy. Periods on that one are 16 seconds, so it’s a long-period groundswell, but with that height it’s just a long wait between tiny little bumps.
The rest of the run is more of the same – mostly cross-off winds, which keep it lookin’ clean, but heights never get past 0.7 ft and energy stays in the teens or twenties. The Thursday the 27th morning has a light breeze and clean conditions, but again, 0.3 ft with energy of 7. There’s nothin’ to get excited about.
If you’re desperate for a paddle, Sunday the 16th morning is the only time it’s completely glassy, but it’s still a lake. For the rest of it, with such weak, tiny swell and mostly cross-off breezes, the setup looks more interesting for a kite than a surfboard.
No standouts here, folks. It’s a flat spell, pure and simple. Forecasts can change, but for now, leave the board in the car.

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.
