The Lowdown
Alright folks, Rusty here. Let’s get into it. We’re only looking at one spot this time: Praia Tenório.
Right off the bat, the water’s sitting at a nice 72°, which is about a touch warmer than normal for this time of year – a little gift from the ocean.
The next week and a half or so has a real mixed bag of energy. We start off with some decent swell on Monday the 24th, a solid 7ft from the south, but it’s coming with a light cross-onshore breeze and some rain, so it’s not the cleanest. The real magic kicks in from Tuesday morning the 25th. That’s when we get a lovely 6ft south-southeast swell, with clean cross-offshore wind from the east-northeast. This is the standout. The combined energy is strong (1222), and those 14-second intervals tell you it’s a proper groundswell with some punch. For a break like Praia Tenório, that’s going to be a fantastic, open wave.
Wednesday the 26th is also looking prime. The morning is pure glass – wind is basically nothing, just 3 mph from the east-southeast, and you’ve got 4ft of clean, lined-up swell. It’s not huge, but the quality is gonna be top-shelf. The afternoon picks up to 6ft with that same cross-off wind, and the energy jumps again (1240). That’s another beauty session.
Thursday the 27th morning is glassy again with a 5ft swell from the SSE. This is a classic run of clean conditions. The energy is still pumping (1128). It’s a great window.
Then things drop off. From Friday the 28th onwards, we see the swell fade hard, dropping to under 3ft, and eventually to practically nothing for several days. There’s a real dead spell from the 28th through to the 31st. A bit of wind kicks up on the 31st afternoon, but it’s onshore and messy with almost no wave height. That’s a write-off.
We get a pulse of new energy coming back in around Tuesday the 3rd of September. That morning has a 5ft south swell with long 12-second periods, but the wind is cross-shore and it’s a little lumpy. The energy is there (773) but the conditions aren’t perfect. Thursday the 5th of September morning looks better – a 6ft south swell, glassy wind, and a decent energy reading (553). That’s the second real highlight in the longer range, but it’s a bit further out, so keep an eye on it. By Sunday the 7th, there are some clean mornings with smaller, surfable waves but nothing that blows your hair back.
Overall, the best on offer is hands-down Tuesday morning the 25th through Thursday morning the 27th. That’s the sweet spot. Clean winds, a consistent long-period swell from the SSE, and plenty of energy. If you can get out there, that’s the window. The rest of the outlook is either flat or only offering choppy, marginal conditions.
Rusty out.

Information about the Praia Tenório Surf forecast
The above surf forecast table for Praia Tenório provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Tenório can be found by selecting the local surf guide option on the grey menu. Our Praia Tenório 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 (Praia Tenório) 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 Praia Tenório 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.
Praia Tenório is 4 km (2 miles) from the city of Ubatuba. If you plan a holiday in São Paulo, look for hotels and other accommodation in Ubatuba. Ubatuba has rooms for a wide range of budgets as well as car hire and transport links.
