The Lowdown
Alright, Rusty here. Let's talk about what's on offer for the local stretch at Praia Tenório.
We're looking at a pretty quiet couple of weeks ahead. The swell is mostly small, and the real standout window is a bit of a wait. The water is sitting at 72° with a touch warmer than normal anomaly, so that's a nice little bonus – a bit more comfortable than usual for this time of year.
The best bet in the whole outlook is Friday morning, September 4th. That's the one to circle. We've got a clean 3 ft S swell at 10 seconds, and the wind is going to be glassy with an easterly breeze. The combined energy is moderate at 285, and the conditions are flagged as good. It's not going to be huge, but that's the cleanest, most promising window we've got.
Before that, the first week is pretty ordinary. Wednesday afternoon the 26th and Thursday the 27th have some waist-high SSE swell, around 5 to 6 ft, but the cross-shore wind and light chop make it feel marginal. The energy is strong though, around 1240 and 1156, so there's power in the water, but the wind is not doing us any favours. Friday morning the 28th is glassy but the swell drops to 3 ft with only 210 energy, and it's just surfable, nothing special. From Saturday the 29th through to Tuesday the 1st of September, it's pretty much flat, with tiny waves and poor conditions until a little bump on Tuesday afternoon.
The second week is a mixed bag. Wednesday the 2nd and Thursday the 3rd have some small, glassy windows but the swell is short period and weak. The standout Friday the 4th morning is really the highlight. After that, Saturday the 5th onward is mostly tiny, with poor surf and very little energy. There's a small pulse on Tuesday the 8th with a 2 ft S swell at 12 seconds, but it's only surfable, not a standout.
So, the call is: wait for Friday morning, September 4th. That's your best chance for a clean, fun session. The rest of the time, it's a lean spell.
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.
