The Lowdown
Alright, Rusty here, breaking down Praia Tenório for you.
First off, the water temp is about what you’d expect for this time of year – nothing weird, no warm or cold surprises.
The main highlight hits on Thursday, September 3rd. The morning brings a clean, glassy 5 ft swell from the SSE with moderate energy (524) and an 11-second period. That’s proper groundswell – good shape, easy paddling. Offshore wind out of the east at 3 mph keeps the faces smooth. For a beginner-plus break like this, 5 ft is a fun, manageable size. Crowds are only 'sometimes' an issue, so you’ve got a solid shot at getting a few uncrowded ones. That Thursday morning is the call.
Thursday afternoon, the wind picks up to 9 mph cross-shore – still rideable but not as clean.
Friday the 4th drops to 3 ft under glassy winds – very ordinary but surfable if you’re keen.
Saturday through Monday gets messy: small surf Saturday, then 5–6 ft on Sunday and Monday but with onshore wind and a short 7–8 second period. That is junky windswell with poor conditions. Skip it.
Tuesday the 8th of September offers another decent window: light rain but a clean cross-offshore breeze from the ENE at 6 mph. Swell runs 4–5 ft from the south at 11 seconds – moderate energy (410). A good morning wave, not the standout, but solid.
From the 9th to the 11th, it goes tiny – knee-high leftovers, mostly glassy but too small to get excited about.
Then around the 15th of September (Tuesday), something stirs again. The morning brings glassy conditions with 3 ft of SSE swell at a 13-second period – that’s long-period groundswell, energy at 295. Clean and shaped. The afternoon of the 16th (Wednesday) is also glassy calm with 2–3 ft south swell at 13 seconds – not big, but that period and glassy water will produce clean, peelable waves.
So, the real standout is Thursday morning, September 3rd – bigger swell, glassy, clean. The secondary windows on the 8th and around the 15th are worth a look if you miss that first one, but the farther out you go, the less certain it gets. Still, keep your eyes peeled.
That’s my take.

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.
