The Lowdown
Alright, grab your board, let's talk about what's coming up for the home break at Praia Tenório.
We’ve got a bit of a slow start, but things are shaping up with some solid windows of clean surf. The water is sitting at a very warm 73°, which is about 4° warmer than usual for this time of year, something you’ll definitely feel in a thin wetsuit or just boardies.
The first real action that’s worth paddling out for lands on Monday morning, August 10th. The swell is running 5ft at 12 seconds from the S, with moderate wave energy (736). The morning wind is light onshore, making it a bit of a fight, so it’s not a standout, but there’s something to ride.
Tuesday the 11th sees a boost in size and energy with 6ft at 13 seconds from the SSE and a strong energy reading of 1139 in the afternoon, but the cross-shore winds are holding it back. It’s surfable, but it’s not clean.
The first real standout window hits Thursday morning, August 13th. Glassy conditions, 4ft swell from the SSE at 13 seconds (563 energy). That’s clean, inviting, and perfect for beginners and cruisers. Friday morning, August 14th, is a carbon copy – glassy, 4ft, same SSE direction. Two mornings in a row of silky conditions. Hang loose.
From Saturday the 15th through Wednesday the 19th, the surf drops off significantly and the conditions get messy. We’re looking at a gap of nearly 5 days where the quality just isn’t there for a proper session.
Things turn around big time on Tuesday morning, August 25th. This is the standout of the whole forecast. Praia Tenório is looking at 4ft swell from the SSE with a very long period of 16 seconds. The energy is massive at 1044, and we’ve got glassy winds. That’s a long-period groundswell hitting a fairly exposed beach, so expect long, clean lines and some real power. In the afternoon, it builds to 6ft from the S at 14 seconds with 1212 energy, still glassy. This is the best window by far—clean, powerful, and well-shaped. It will be too big for pure beginners, but you’ll be smiling.
After that, the swell fades back down into small, marginal waves.
Overall, point your truck toward Praia Tenório on the mornings of August 13th and 14th for the most user-friendly fun, but if you want power and perfection, circle Tuesday the 25th on your calendar.
Stay stoked,
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.
