The Lowdown
Alright, I’ll level with you, pal – the next 16 days are a total flat spell for Sao Pedro. This point hardly ever breaks, and this forecast proves it. You’re looking at a whole lot of nothing.
Thursday morning, the 20th of August, it starts off tiny. We’re talkin’ a 0.7ft swell out of the SSW, with a long 13-second period. Wind’s a light cross-off from the NNW at 6 mph, so it’s clean. But the energy is weak, just 17 (combined swell energy). Not a ripple you could ride. Water’s about 69°, which is normal for this time of year.
Friday and Saturday are more of the same: 0.7ft swell, clean wind, but zero power. The swell period is long, over 14 seconds, which is the kind of groundswell a point like this craves, but the height is laughable. It’s a real bummer.
We get a little bump Sunday the 23rd, with the energy climbing to 44. But the quality goes straight in the toilet. Sunday morning serves up a short, choppy 4-second swell from the S at 3ft, with a moderate cross-onshore breeze. By the afternoon, the wind is onshore from the S at 16 mph, making a mess of the 5ft waves.
Monday the 24th brings the biggest surf of the entire run – a 7ft swell out of the WSW. The energy hits 518 (moderate to strong). But it’s short-period wind swell at 8 seconds, with a moderate cross-onshore wind from the WSW at 16 mph. “Poor surf conditions” is the call. At that size and with that wind, the beach breaks would be better for kite surfing than anything on a paddle board.
Then it all dies. From Tuesday the 25th right through Friday the 4th of September, it’s back to 0.3ft to 0.7ft of nothing. The wind stays clean for most of it, which feels like a cruel joke. The energy drops to single digits – just a dead ocean.
There ain’t a single standout session in this whole 16-day window. For a wave that “rarely breaks,” this dry spell is pretty normal around here. Could the forecast shift? Sure. But right now? Don’t even bother waxin’ up.

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.
