The Lowdown
Alright, let’s get down to business for Praia-Tenório over the next couple weeks.
We kick things off on Friday morning, August 14th, with some solid southeast groundswell at 1.3m. It’s glassy and calm out there, so the lineup should be clean and inviting. Water’s about 72°F, which is a touch warmer than average for the season – pretty comfortable.
Then Saturday morning, August 15th, is the one to circle in your calendar. The swell pushes up to 6ft from the SSE with a long 13-second period, and the wind is light and cross-off. The energy in the water is strong, reading 1180, and it’s shaping up to be very good surf. This is your biggest and best window. It’s a bit much for the learners, but for the regular crew, it’s game on. The direction is right for the break, so expect some proper waves.
The rest of the weekend fades fast. Saturday afternoon drops to 4ft and goes messy with the east wind. Sunday is smaller and poor. Monday the 17th offers a small, glassy dawn session, but it’s nothing special.
Then we hit the flat spell from the 18th through the 24th. A proper lull. If you can’t paddle, you’re doing something else. There’s a tiny bump on the 21st and 22nd, but it’s not worth the paddle out.
Looking further ahead, and this is a long-range hint more than a promise, Tuesday the 25th shows some life. Swell builds back to 3ft from the south with a good 12-second period. Tuesday afternoon looks the cleanest with glassy conditions and light airs. It’s not huge, but it’ll be a fun, clean wave. The days after that stay rideable but nothing to get too worked up about.
So, your best bet is Saturday morning. Make the most of it. The flat spell is real, but there’s hope at the end of the tunnel.

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.
