The Lowdown
Alright, surfers, Rusty here with a look at the 16-day stretch for São Pedro. Let's get straight into it.
Truth be told, I've been staring at the charts and this is a tough one. We've got a long, flat spell ahead. The first real whisper of a wave doesn't show up until Monday morning the 17th of August, and even then it's barely a tickle. The whole period is a struggle for any decent surf.
You're looking at a solid gap from now right through until Monday the 17th with absolutely nothing on offer. Even when that little bump arrives, it's not surfable. We're talking about a tiny 0.3ft to 1ft swell from the SW for the first several days. The energy is weak as dishwater – you’ll see values under 50 in the combined energy readings, like a paltry 20 on Monday morning. The water temp is sitting at 68°F, which is pretty average for this time of year.
On top of that tiny swell, the wind is all over the place early on, mainly cross or onshore, killing any chance of a rideable wave. Later in the week, from Thursday the 21st through the end of August, we get some clean, cross-offshore winds from the NNW, but the swell is still non-existent. It’s clean, but flat as a pancake.
Even into the first of September, the story stays the same – a bit of wind but no real push of swell. The energy numbers are in the single digits most of the time, confirming the ocean is sleepy.
Honestly, this is a classic case of a very quiet spell. São Pedro is a point break that rarely breaks as it is, and this forecast confirms it. For a surfer, there’s just nothing to get excited about. For a kitesurfer? The consistent, clean cross-offshore winds from the NNW that blow for days on end would be a dream. But for a paddle surfer, I’d be looking at other plans or just waiting for the next storm track to wake things up.
Stay tuned, forecasts change, but for now, the racks are dry.

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.
