The Lowdown
Alright, let’s break it down. Rusty here.
First thing, Praia Tenório. Honest truth, the first week is a total dud. From Friday the 17th right through to Monday the 27th, the surf is practically flat. You’ll see some glassy mornings, but the swell is tiny, often under 2ft, and the energy is weak (combined energy often under 100). It’s not worth paddling out for. That’s a solid ten-day stretch of nothing. It looks more like a kiteboarding setup than a surf spot for a while.
Then, finally, we get a pulse. The first real standout is Saturday the 25th of July. The afternoon is the call. The swell picks up to 4ft from the SSE, with a moderate 10-second period, and the combined energy hits a solid 343 – that’s moderate wave energy. The wind goes glassy, dead calm from the east. That’s the dream – clean, lined-up waves. The break is fairly exposed, and crowds are listed as “sometimes,” so you might see a few others, but it’s nothing heavy. This is your best bet for a fun, friendly session.
Now, for the big boys. Lock in Thursday the 30th of July. The morning session is the standout. We’re talking a solid 8ft swell from the SSE, with a very long period of 14 seconds. That’s proper groundswell, and the combined energy is a massive 2517 – that’s strong wave energy. This is excellent surf, but only for experienced surfers; anything over 8ft is expert territory. The wind is glassy from the WNW. The water temperature is about average for the time of year, nothing wild. This is the one to aim for, but remember, long-period swell like this can be a bit straight at a beach break, so keep an eye on the shape.
The following Friday and Saturday still have a lot of energy, but the wind gets a little messy, so the quality drops off a bit.
So, the verdict: a long quiet spell, then a clean Saturday on the 25th, and a proper power session for the experts on the morning of Thursday the 30th. Get after it.
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.
