The Lowdown
Alright, Rusty here. Let’s get straight into it for this stretch of coastline.
To be honest, the next sixteen days are a tough watch. The swell is all over the place and mostly tiny, so we are looking at a long, flat spell. The first real gap starts pretty much now, and we’re looking at nothing rideable until late in the run. It’s a bit of a bummer, but that’s the way it goes sometimes around here.
Looking at Thursday the 23rd of August, there’s a little bump in the water, but it’s a messy situation. Sao Pedro is seeing a bit of swell pushing in from the SSE at 3ft, but the period is a shocking 4 seconds. That’s pure wind slop, and with a fresh cross-onshore wind, it will be lumpy and frustrating. The wave energy is weak at 37. Not one for the board.
Sunday the 20th of August. The water temp sits at 69°F, which is around average for this time of year.
The best of a bad bunch shows up on Monday the 24th of August. We get a jump in size with a WSW swell at 8ft and an 8 second period. That’s a lot of water moving, but it’s still short-period stuff, and it’s coming straight onshore from the SW with a 9 mph wind. The combined energy reads high at 695, but it's going to be a mess at Sao Pedro – a beach and reef setup like this will have poor quality, and frankly, it looks way more interesting for a kite surfer than a paddler. It’s expert-only at that size, and the wind is a killer.
After that, it fades right back to tiny, ankle-snappers through the end of August and into September. Nothing gets above 0.7ft, and the period gets long over 15 seconds, but with no height, it’s just a flat ocean. We see a hint of a glassy morning on Thursday the 4th of September, but with only 0.3ft of swell on offer, you wouldn’t even get your feet wet. The wait continues.
It’s a blank run for the area. When even the long period groundswells can’t pick up any size, you just have to wait for the next weather system to change things. Forecasts can change, but right now, there’s nothing to chase.
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.
