The Lowdown
Alright folks, Rusty here. Let's have a look at what’s coming up for Praia Tenório.
Right off the bat, we’ve got a solid pulse of swell arriving now. Wednesday morning the 12th is looking really promising, with a clean 5ft SSE groundswell and glassy, offshore ENE airflow. The water is feeling much warmer than usual for this time of year at 73°, which is a nice bonus. The wave energy is moderate to strong (718), and with that 12-second period, we're talking proper, lined-up waves. This is the standout of the near-term.
The good conditions hold into Thursday the 13th. Thursday morning is an absolute gem – completely calm, glassy conditions with a consistent 5ft SSE swell. The period bumps up to 14 seconds in the afternoon, adding even more punch. This is a very clean, inviting swell for the beginner-plus crew that this spot usually suits. Friday the 14th stays clean with glassy winds and 4ft swell, but the energy drops a notch (599). It’s still good surf, just not quite as powerful.
Saturday the 15th gets a bit messy. The swell bumps back up to 6ft, but the wind turns cross-on and there’s a risk of thunderstorms. It’s a downgrade from the earlier days.
Things really drop off after that. From Sunday the 16th, we hit a long flat spell. There are several days with tiny, weak waves – nothing worth paddling out for. We’re talking over a week of poor to non-existent surf from Sunday through to the following Saturday the 22nd. It’s a proper dead patch.
The pulse returns on Sunday the 23rd, with building swell. By Monday the 24th, we're back in business with a clean morning, calm winds, and a solid 5ft S swell. But the real standout of the whole outlook is Monday the 25th into Tuesday the 26th.
Monday the 25th morning has light cross-offshore winds with a 5ft SSE groundswell at 14 seconds – that’s a serious amount of energy (845). But Tuesday the 26th morning is the one to circle on the calendar. We’ve got a 8ft S swell with a 13-second period and glassy, calm conditions. The wave energy is massive at 2983. This is powerful, ground-swell generated surf, and the description says excellent conditions for experienced surfers. For the more advanced crew, that Tuesday is the best wave of the whole 16-day window. Just be aware that this is a long-range call, so the exact timing might shift, but the potential is undeniable. The water on that Tuesday morning is also glassy and clean.
So, to sum it up: get after it Wednesday through Friday this week, then wait out the doldrums. The big prize is Tuesday the 26th of August for the experienced crew, with a solid build-up starting the Monday before.
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.
