The Lowdown
Alright, folks, Rusty here. Let's get straight into it for this stretch of coast. We've got a long outlook ahead, but I'll be real with you – it's a bit of a flat spell.
Right off the bat, we're looking at a pretty grim run. The swell is almost non-existent. We're talking about tiny, tiny waves for the entire 16-day window. The first few days are a write-off. From Saturday the 15th right through to the end of the month, it's going to be a struggle to find anything worth paddling out for.
The only spot on the cards is Sao Pedro. This is a sheltered point break, and it's a beginner-friendly wave, but it's also one that "rarely breaks". Unfortunately, that's holding true here. The swell energy is weak, with values stuck in the single digits and low teens (like 12 to 48) for the whole period. When the swell does show up on Tuesday the 18th afternoon, it's a tiny 1.0ft from the SW with a period of 16 seconds. That's a long period groundswell, which is good for shape, but with that little height, it's barely going to wrap in.
The water temperature is sitting at about 69°, which is only 0.7° cooler than normal for this time of year. So, pretty average for the season.
There is a small window on Thursday morning, the 20th of August, where the wind goes glassy. That's a major positive, but with only 0.7ft of swell from the SSW, it's a session for a float, not a surf. The crowd situation at Sao Pedro is listed as "often", so if it were breaking, you'd have company. But on this forecast, it's not going to be an issue.
The best of a very bad bunch might be the late afternoon of Saturday the 30th of August. We see a 0.3ft, 17-second period SW groundswell with clean, cross-offshore winds. But again, we're talking about a ripple. There are no standouts here. Honestly, this coastline is in a flat spell. It's the kind of dry run that's more normal for a protected spot like this when the swell direction isn't aligned.
With the swell so small and the wind often clean, some of the beachier sections might look tempting for a kite surfer, but for a paddle surfer, this is a 16-day wait.
Keep your eyes on the charts; things can change, but for now, don't bother waxing up.
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.
