The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Praia Tenório over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week is a bit of a slow burner. Monday the 3rd and Tuesday the 4th are flat as a pancake, with tiny dribbles of 0.3ft to 1ft on offer. The water temp is about average for the time of year, so nothing weird there. You’ll be staring at a glassy surface but with next to no push. Wednesday the 5th morning sees a slight bump to 2ft from the S with a 12-second period, and the combined energy ticks up to 132 (moderate energy), but it’s still very ordinary. Thursday and Friday stay small, with the swell dropping back under 2ft. It’s not until Sunday the 9th that we finally see some life.
Now, Sunday the 9th is where things get interesting. The morning brings a solid 3ft S swell, but the period jumps to a very long 16 seconds. That’s proper groundswell energy, with the combined energy hitting 545 (moderate to strong). The wind is light offshore from the N, so the morning session will be clean. By the afternoon, the swell bumps to 4ft from the S, period still a very long 15 seconds, and the energy is up to 734 (strong). The wind goes light cross-off from the WNW. This is the standout window of the whole forecast – clean, lined-up groundswell. Just remember that long period stuff like this can be a bit tricky at a beach break, but for a fairly exposed spot like Praia Tenório, it should hold.
Monday the 10th gets messy with onshore winds, and Tuesday the 11th is a write-off with 12 mph onshore winds and rain. Wednesday the 12th morning, though, is a sneaky good one. The swell is a legit 7ft from the S, with a moderate 11-second period, and the combined energy is a pumping 1023 (very strong). The wind is glassy – dead calm. That’s a heavy winter swell with not a breath of wind. That’s expert territory though; 7ft is pushing it for beginners. The afternoon sees the wind swing onshore, so get out early.
After that, the swell slowly backs off through the second week. Thursday the 13th morning is still decent with 5ft from the SSE, glassy conditions, and strong energy (553). Friday the 14th and Saturday the 15th are small and unremarkable. Sunday the 16th morning brings a cleaner 4ft SSE swell with a 13-second period and glassy conditions, which is worth a look if you’re desperate. The rest of the run is small or wind-affected.
So, to sum it up: the best bet is Sunday the 9th for the long-period groundswell with clean winds, and Wednesday the 12th morning for the biggest, glassy 7ft swell. The mid-week is a write-off, and the second week only has a handful of small windows. Crowds? With only one break in the area, expect company on the good days, especially Sunday.
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.
