The Lowdown
Alright folks, Rusty here, looking at the forecast for our stretch.
Alright, the first few days of this outlook are a mixed bag, but there are a couple of absolute gems to get the stoke up. The water is running at 72° which feels a touch warmer than normal for this time of year. We've got plenty of action on the cards, but you gotta pick your moments as a lot of it is hampered by wrong winds, especially in the middle of the window.
Let's start with the good stuff. The standout window is the 26th to the 27th of August. We've got a real pulse of solid swell coming through. Wednesday morning the 26th sees clean 4ft from the SSE (12s period) with glassy conditions. That's a beautiful start. But the real highlight is Wednesday afternoon on the 26th. The swell bumps up to a nice 6ft from the SSE, but the period stretches out to a juicy 15 seconds, giving us proper long-period groundswell energy. The combined energy is on the strong side at 1240, meaning there's plenty of push. The morning is glassy, so get on it early.
Then Thursday the 27th serves up another ripper. Morning session is 5ft from the SSE (14s period) with that sweet, clean glassy wind. The combined energy is still strong at 1076. This is when a south swell like this works well at Praia Tenório – that long period will wrap in nicely, offering well-shaped lines. Crowds can happen here, so expect it to be busy if you're chasing that morning glass.
After Thursday, things drop off. Friday the 28th and Saturday the 29th are a write-off with tiny, weak surf. The combined energy drops to 210 and then down to a pathetic 22. Not worth paddling out for.
There’s a gap of almost no surf until the next decent pulse arrives on Thursday the 3rd of September. We get another solid morning of 6ft from the SSE (10s period) with glassy, clean conditions. The combined energy is at 725, which is a solid moderate-to-strong pulse. This is a proper wave, over 5ft, so it’ll be pushing into intermediate territory, but with the clean wind it will be worth it.
Beyond that, the surf fades again into smaller, mixed-up conditions through the first week of September, with some cleaner but smaller days around the 7th and 8th with glassy conditions on swells of 3ft to 4ft.
If you only get one session, make it the super clean, long-period swell on Wednesday morning the 26th of August. It’s the best on offer. Otherwise, the Thursday the 27th morning is a very close second.
Rusty, signing off.

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.
