The Lowdown
Alright, Rusty here. Gotta level with you, it’s been a tough stretch. Pulling up the outlook for Sao Pedro (São Miguel), and honestly, for the next two and a half weeks, there’s nothing to get excited about. We’re looking at a near-total blank period, so don’t be in a rush to wax up.
The water is sitting at about 69°, which is pretty much what you’d expect for this time of year, nothing wild there.
Kicking off Tuesday the 18th, it’s flat. We’re talking tiny, weak scraps. Swell heights barely tickling 1 ft from the SW with a long period of 16 seconds, but the energy is negligible at just 43 (weak). Winds are light but variable and onshore, making what little there is a messy, poor surf situation. That same story runs through Friday the 21st. By Saturday the 22nd, the wind picks up strong from the NNW, still cross-offshore, so the surface is clean, but the swell is still only 0.7 ft; the energy is barely there at 40. It’s clean, but there’s nothing to ride.
This miserable run of tiny, weak swell (energy readings all under 40) and clean but empty conditions stretches on. The wind is mostly fresh to strong from the NNW, keeping the water smooth, but the wave heights are stuck at 0.3 ft to 0.7 ft. This goes all the way through the end of August and into the first couple of days of September.
There’s a slight flicker on Tuesday, September 2nd, with a moderate offshore wind from the NNE in the morning, keeping it clean. But the swell is still a pathetic 0.3 ft from the SW with energy at just 8. You’d be bobbing around on a lake, not surfing.
In short, there are zero good surf options in this 16-day window. Sao Pedro rarely breaks, and this is one of those classic blank runs where the area just goes to sleep. It’s clean enough for a paddle or a swim, and likely more interesting for a kite surfer needing some wind than a paddle surfer needing a wave. Forecasts can change, but right now, it’s a hard pass.
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.
