The Lowdown
Alright, let’s get into it. Things are pretty flat for a while here at Praia Tenório, so don’t be in a rush. The first few days are a write-off—tiny, weak, and messy. We’ve got a solid stretch of poor surf from Sunday the 30th right through to Tuesday the 1st of September, with swell barely cracking 2 feet and the wind ruining any chance of a wave. It’s a real slow start.
Then, on Tuesday afternoon the 1st, we get a little glimmer. The wind goes glassy, and the swell bumps up to 3 feet from the south, but it’s short-period stuff (7 seconds) and the combined energy is still low (89). It’s surfable, but only just. Not worth getting excited about.
Wednesday the 2nd is a mess again—moderate cross-onshore wind and choppy conditions, even though the swell bumps up to 6 feet in the afternoon. That’s too big for beginners, and the wind is onshore, so it’s a no-go for most.
Now, here’s where it gets interesting. Thursday the 3rd and Friday the 4th, we get some cleaner windows. Thursday morning is glassy, with 4 feet swell from the SSE, period 8 seconds, and energy at 240 (moderate). Friday morning and afternoon both go glassy, with 3 feet and 3 feet from the SSE, period 10 seconds, energy dropping from 204 to 171. It’s not pumping, but it’s clean and surfable. The water temp is about average for this time of year, so no surprises there.
The real standout is Monday the 7th of September. Monday afternoon brings glassy conditions, 8 feet swell from the SSE, period 14 seconds—that’s a proper groundswell with lots of energy (2478). This is only for experienced surfers, as it’s well over 8 feet. The long period (14 seconds) means it’ll be lined up, but at a beach break like Praia Tenório, it might break a bit straight. Still, with glassy conditions, this is the best session on offer.
Tuesday the 8th morning is also a standout: 8 feet from the SSE, period 16 seconds (very long), energy at 3113 (strong). The wind is light cross-offshore, so it’ll be clean. Again, experts only. The long period means the sets will be well-spaced, making the paddle out easier, but it’s a big, powerful swell.
After that, it drops off. Wednesday the 9th morning still has 5 feet from the SSE, period 13 seconds, and glassy conditions (energy 696, moderate). That’s a good session for confident intermediates. But by Thursday the 10th, it’s fading back to small, clean but ordinary waves.
The second week (from the 10th onwards) is mostly small and weak, with a few glassy moments but nothing to plan a trip around. The 12th and 13th are tiny, with energy dropping below 100.
So, the best advice? Hang tight for Monday the 7th and Tuesday the 8th. That’s the real deal, but only if you’ve got the skills for heavy, long-period waves. For the rest of us, Thursday the 3rd and Friday the 4th are your best bet for a clean, manageable session.

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.
