The Lowdown
Alright folks, Rusty here. Let's be straight up, this is a tough stretch for surf here at Sao Pedro. It's a point break that's sheltered and rarely breaks anyway, so we need a perfect storm of conditions. Over the next sixteen days, we're looking at a whole lot of nothing, with a few tiny, almost hopeful bumps that just don't cut it.
The run starts on Saturday, the 12th, with a tiny 0.3ft swell from the S. That's basically a lake. We've got clean conditions with a light offshore, but with combined swell energy a weak (3), there's just no push. This poor pattern continues for days. There's a long gap with no recommendations at all. Sunday the 13th through Tuesday the 15th, there are periods with zero swell and poor surf conditions. On Wednesday the 16th, we see a tiny bump again, 0.3ft from the S with a period of 13 seconds, but still poor. By Thursday the 17th, the period stretches to 16 seconds, which is a very long period groundswell, but the height is still a paltry 0.3ft and energy is only (13). That's a classic tease – all that potential energy with zero height.
The closest thing to a standout, and I use the term loosely, is Friday the 18th. The morning brings a 0.3ft swell, but this time it's from the SW, which is the optimum direction for this break. We get a gentle offshore wind and clean conditions. The combined energy is still weak at (9), so don't expect any real power. Then again, on Monday the 21st, we get a slightly bigger 1ft swell from the S, but with a short period of only 5 seconds. It's glassy in the morning though, which is nice for a paddle if you're desperate.
Honestly, the best day looks like Sunday, the 27th. It's late in the window, so treat it as a long-shot, but the morning shows a 0.3ft SW swell with a consistent 12-second period and a cross-off breeze. Energy is still low at (7), but it's the most consistent-looking signal we have.
The bottom line: Sao Pedro is almost never on. When it's not, it's just flat. This is a blank run that is all too normal for the area. Wait for a proper swell to hit. If the wind is up and there's any ripple, this sheltered setup would be more interesting for a kite than a surfboard.
Rusty, out.

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.
