The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaking for the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. Saturday and Sunday are pretty flat with tiny, weak swell that’s not worth paddling out for. The water temp is about average for this time of year, nothing out of the ordinary.
The first real glimmer of hope comes on Monday, the 2nd of September. Now, listen, we’ve got a massive 10ft swell from the south rolling in, with a long period of 14 seconds – that’s serious groundswell energy. The combined energy is reading a whopping 3543, which is strong. But here’s the catch: that’s too much juice for Praia Tenório. It’s going to be a washing machine and only for the experts, if anyone. The wind is light and cross, so it’s not blown out, but the size is the issue. This is more of a spectacle than a session for most.
Skip the rest of that week as it’s small and messy.
The real standout, the one you’ve been waiting for, is Tuesday, the 8th of September. We’ve got a 6ft swell from the SSE, with a period of 13 seconds – that’s solid, clean groundswell. The energy is up at 1030, so there’s some proper push. But the best part? The wind is glassy. Zero wind. It’s going to be clean as a whistle. The surf is set to be very good, with shape and power. This is the pick of the forecast. It’s a beginner-plus spot, so it’s approachable for intermediates, but the quality will have everyone smiling. Keep in mind, it can get crowded here sometimes, so get in early.
The following morning, Wednesday the 9th, holds some okay waves but the wind shifts onshore and the quality drops. Thursday the 10th is looking marginal. The next proper highlight is Friday the 11th of September. Another SSE swell, 4ft, with a long 14-second period, and glassy conditions again. The energy is 749, and it’s set to be very good surf. This is your second standout session – clean, lined-up waves.
After that, the swell backs off and the winds get messy, so the window closes for the weekend.
So, to wrap it up: if you can only pick one day, make it Tuesday the 8th of September. The combination of a solid, clean groundswell and glassy wind is a rare treat. The Friday the 11th is a close second. The rest of the run is either too small, too big, or too windy.
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.
