The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for the stretch ahead. I’ll be straight with you – it’s a quiet outlook for our patch, so don’t go getting your hopes up for anything epic.
We’re looking at a long, quiet run with no real surf on offer for the entire 16-day window. The first record shows a little bump on Saturday, 12 September, but it’s tiny – just 0.3 ft from the south with a long period of 13 seconds. That’s a groundswell, and while the period is nice, the size is barely a ripple. The wind is offshore (NNE at 3 mph) in the morning, which would make it clean, but there’s simply not enough energy to ride. The combined swell energy is just 3, so it’s weak as dishwater. The water temperature is 67°, which is a bit colder than normal for this time of year (anomaly of -3°). At Sao Pedro (point), which rarely breaks anyway, this is a no-go.
From Sunday morning onward, it’s flat or next to it. There’s a string of days from Sunday, 13 September right through to the end on Sunday, 27 September where the swell height is either missing entirely or stuck at that same tiny 0.3 ft. No quality surf conditions at all. The winds are often offshore or cross-offshore, but without any swell to work with, it doesn’t matter. The combined energy values hardly ever climb above single digits – the highest being 13 on the Thursday afternoon of the 17th, and that’s still weak.
Honestly, for a spot like Sao Pedro that rarely breaks, this kind of blank run isn’t unusual. There’s no standout day, no standout session. The only thing worth noting is that if you’re desperate for a paddle on a glassy surface, the Sunday morning of 20 September has glassy conditions (east wind at 3 mph) but still 0.3 ft and poor surf. It’s a kite surfer’s dream with all that clean, light wind and no waves, but for us paddle surfers, it’s a total washout. Keep an eye on the longer-range forecasts – things can change, but for now, leave the board in the car.
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.
