The Lowdown
Alright, let’s get into it. The way I see it, the next couple of weeks are a bit of a mixed bag. We’ve got a slow start, but there are a few windows where things could get interesting. Don’t expect a classic run of perfection, but keep an eye out for a couple of specific sessions.
First up, we’re looking at Praia-Tenório. The water’s sitting at 73°, which is a fair bit warmer than usual for this time of year—over three and a half degrees above normal, so that’s a notable bump. You’ll feel that difference.
The opening days are pretty quiet. Saturday the 8th starts off with some tiny, glassy conditions in the morning—clean but not much push, with a weak combined energy of 44. The afternoon brings a bit more size, but it’s messy with a light cross breeze. Nothing you’d paddle out for.
Sunday stays small and onshore, and Monday the 10th sees the swell pick up a touch to around 5ft, but it’s onshore and rainy, so the quality just isn’t there. The energy is moderate, around 732, but the wind kills it.
We’re looking at a few days of marginal, cross-shore conditions through Tuesday and Wednesday. There’s surfable size, mostly in the 4ft to 5ft range, but it’s not clean. The standout moment in this first week is shaping up for Wednesday morning, August 12th. The wind goes light and cross-offshore, the swell is a clean 4ft from the SSE with a 12-second period, and the energy is moderate at 535. It’s not huge, but it’ll be the cleanest waves we’ve seen so far. That’s your window before the crowd gets on it.
After a couple of ordinary days, things start to look up again. Saturday morning, August 15th is another one to circle. The wind drops to glassy, the swell is a clean 4ft from the SSE with a 13-second period, and the energy is moderate at 507. This will be a proper, clean surf session. The conditions will be lined up, and it should be a fun one.
The middle of the month gets a bit tricky. There’s a dip in energy and a lot of cross-shore wind. The morning of Monday the 17th is tiny, and the afternoon is a mess. Then we get to Tuesday afternoon, August 18th. The wind goes completely calm and glassy, the swell is 4ft from the SSE with a 12-second period, and the energy is moderate at 472. This is another standout—clean, glassy conditions with a decent amount of push. This is likely the best on offer for the whole stretch. It’s not a massive swell, but it’s clean and rideable.
After that, the energy starts to fade. The rest of that week and into the weekend sees the swell dropping back down to under 3ft, with periods getting shorter and the wind turning more cross-shore or onshore. By the 21st, it’s basically flat and glassy—nothing doing. The 22nd brings a bit of a bump but with a strong cross-onshore breeze, so it’ll be choppy and not worth the hassle.
So, to sum it up: the first couple of days are slow, but Wednesday the 12th and that glassy Tuesday afternoon the 18th are your best bets. Keep it in mind, and don’t be afraid to be patient. The water’s warm, and when it’s clean, it’s worth it.

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.
