The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer at Praia Tenório for the next couple of weeks.
Right off the bat, the first few days are a write-off. Saturday the 12th and Sunday the 13th are basically a flat, messy lake with poor surf and onshore junk. Don’t even bother. There’s a glimmer Monday morning the 14th with glassy conditions on tiny 3ft SSE swell, but it’s weak (combined energy of 65) and really only good for a longboard if you’re desperate. Tuesday the 15th brings clearer skies and glassy conditions again, with a bit more energy (188), but still only 3ft to 2ft. It’s ordinary, but you could get a few fun ones on a log. The water is sitting at 72°, which is a touch warmer than normal for this time of year.
The first real standout of the whole forecast is Friday morning, September 18th. We’ve got glassy conditions, a clean 3ft S swell at 11 seconds, and the combined swell energy is up at 351. That’s a solid fun wave for the intermediate crew, not too big, not too small, just clean lines. This is your best bet all week.
Now, hold onto your board, because the real action comes in the second week. Thursday the 24th is a beast. We’re looking at an 8ft S swell with a 14-second period, and the energy is a massive 2570. That is expert territory. The morning is glassy, which is incredible, but this is a serious wave. By the afternoon it jumps to 10ft SSE with a 16-second period and 4340 energy. That’s big and powerful. It might be too much for Praia Tenório itself, pushing the limits of the break. If you’re a charger, that Thursday morning window is the one, but only if you know what you’re doing. Friday the 25th keeps the size with 8ft to 7ft SSE swell, also very long period (16 seconds), and glassy conditions in the afternoon. Another expert-only day.
Saturday the 26th settles down a bit to a much more manageable 5ft SSE at 14 seconds, with glassy morning winds. That’s a fun, powerful wave for advanced surfers, but still big enough to keep the crowds thin. After that, the swell drops back down into the nothing zone for the rest of the period.
So to wrap it up: forget the first week unless you want to play in ankle-biters. Friday the 18th morning is the clear standout for everyone. For the experts, Thursday the 24th morning and Friday the 25th afternoon are the main events, but they’re a promise at this range—keep an eye on it.
Rusty.

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.
