The Lowdown

Alright folks, let’s break down what’s happening at São Pedro. I’m gonna level with you – this is a tough one. This break is sheltered and rarely breaks, so we’re not talking about a classic surf forecast. But there are a few bright spots if you know what to look for.

The first real swell shows up Sunday the 23rd of August, but it’s a write-off. A 3ft southwest swell with a short 6-second period and a fresh cross-onshore wind at 22 mph – lumpy and no good. It gets worse in the afternoon as the swell jumps to 5ft but the wind stays onshore. Monday the 24th brings the biggest swell of the whole outlook – 8ft from the WSW, 8-second period, and strong combined energy. But again, onshore wind ruins it, and at that size with messy conditions, only the real die-hards would even look at it. Not for beginners.

Tuesday morning the 25th is glassy with no wind, but the swell drops to just 0.3ft. You’d be floating. That long-period 12-second groundswell has no power behind it.

From Wednesday the 26th through the end of the month, it’s mostly tiny, weak swell (0.3ft) and onshore or side-shore winds. A few afternoons clean up, but there’s nothing to ride.

Now, here’s where it gets interesting for the patient surfer. From Friday the 28th of August onward, the wind goes clean – cross-offshore from the north and northwest, skies clear. The swell stays tiny (0.3ft to 1ft), but the period gets longer, hitting 15 to 18 seconds by the start of September. That’s real groundswell energy. On Tuesday the 1st of September morning, we see a 0.7ft SSW swell with a 15-second period and a moderate offshore breeze at 12 mph – clean as can be. Not a wave you’d paddle out for on a shortboard, but beautiful conditions.

The standout, if you can call it that, is the morning of Wednesday the 2nd of September. We’ve got a 1ft southwest swell, 16-second period, and a north wind at 16 mph keeping it glassy offshore. At São Pedro, a long-period southwest groundswell with offshore wind is about as good as it gets for this break – clean little peelers if it decides to break at all. Given it rarely breaks, this is a notable window. Crowds are possible here, so expect company if it shows.

The second week stays clean but tiny. The 3rd and 4th of September have similar cross-offshore winds and 0.3–0.7ft swell from the south-southwest, with periods around 13–14 seconds. Consistent and clean, but not much to write home about.

So, bottom line: if you want proper waves, this isn’t the fortnight. But if you’ve got a longboard or a foil and love clean, glassy conditions, the mornings from the 28th of August through to the 7th of September are your best bet. The standout is Wednesday the 2nd of September – the longest-period groundswell of the outlook, light offshore wind, and a rare chance at a wave at a break that doesn’t fire often. Don’t get your hopes up too high, but keep an eye on it.

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.
