The Lowdown
Alright, mate, Rusty here. Let's have a look at the stretch ahead for Praia Tenório.
First thing's first: the water's sitting at a touch warmer than normal for this time of year, coming in at 73°F with a 3°F anomaly. It's a bit of a standout, so you can leave the thicker steamer at home.
Right now, we're in a bit of a lull. Saturday the 5th is looking pretty flat, with just a knee-high 1ft slop and almost no energy behind it (43). It's clean and glassy, but there's just nothing to push you around. Don't bother paddling out unless you're desperate for a splash.
Sunday the 6th sees a whole lot more water moving, but it's not good. The swell jumps to 7ft but it's a short-period, onshore mess, with the wind howling from the S at 12 mph and rain coming down. The energy is moderate (762), but the conditions are junk. This is a write-off.
We finally get a few proper windows early next week. Monday the 7th is the one to really look at. It's not huge, with a 6ft SSE groundswell and a 10-second period, but it's glassy. The wind is light from the SW, there's a bit of rain around, but the ocean is clean. Wave energy is solid (707), and this is about as good as it gets in this stretch. It's a "fairly consistent" break, but on a day like this, with the offshore winds, it could be worth a look.
Tuesday the 8th settles down but the size drops too. The swell backs off to around 3ft, the wind goes calm, and conditions stay glassy. It’s surfable – you'll be noseriding on a log – but it's just ordinary. The energy drops right back (188). Not a standout.
Then we hit a few days of diminishing returns. Wednesday the 9th is small, crossing winds, and just poor. Thursday the 10th and Friday the 11th tease you with 3ft and 2ft swells, but the period stretches out to 12 and 13 seconds. That long period at a beach break tends to make things close out and section. It's clean on Thursday morning, but it’s not going to have any push.
The weekend of the 12th and 13th is a proper flat spell. Swell drops to ankle-biters on Saturday, and while Sunday sees a quick pulse to 7ft, it's a short-period windswell with bad cross-onshore winds and rain. Forget it.
Now, let's talk about the real event. The big one is lining up for Monday the 14th through Tuesday the 15th. We're looking at a proper groundswell.
Monday the 14th brings a massive 10ft SSE swell with a 13-second period. The energy is off the charts (2454). The wind is light offshore in the morning, which would normally be a dream. But here's the catch: it's too big for this place. It's going to be a washing machine. Unless you're a proper expert, stay on the sand and watch. It's a "beginner plus" spot, so this is way out of its comfort zone.
That sets up Tuesday the 15th as the true standout. The swell eases to a still-chunky 7ft, the period holds at 12 seconds, and the wind drops to dead calm, glassy conditions. The energy is still very strong (1478). The direction is SSE, which aligns with the optimum. If you're an experienced surfer, this is your session. It’s going to be powerful and lined up. This is the one to circle on the calendar.
After that, the plug gets pulled. Wednesday the 16th drops right back to under 3ft of weak, ordinary surf. And from then on, it's a slow fade into flatness. There are a few ankle-biters through the end of the period, but the energy is pathetic (down to single digits by the 20th). The long period swells keep the lines clean but they won't have any push to get you going.
So, don't get excited about the next few days. Get your board ready for Tuesday the 15th – that’s the big one. Get out there early before the winds pick up.

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.
