The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up for Praia Tenório. The next couple of weeks are a slow burn – a long, flat spell to get through before any real surf returns.
We start off with a bit of tiny, clean swell on Tuesday afternoon. We’re looking at a weak 2ft south swell with a 9-second period, but the water is a touch warmer than usual at 73°, which is nice. The real story is that it’s glassy and the combined energy is weak (144). It’s surfable, but honestly, very ordinary. Don't get your hopes up.
Wednesday morning stays small and glassy, then Wednesday afternoon sees a slight bump to 3ft from the south, with the period stretching out to 12 seconds. The combined energy jumps to moderate (214), still glassy. It’s the high point of this first week, but that’s not saying much.
From Thursday morning through to the end of the following week, it’s a desert. The swell drops, the wind gets messy, and the conditions turn poor. We get at least a full week of nothing worth paddling out for. There's a few days with cross-shore winds and tiny waves, but it’s not gonna be fun. The combined energy drops to as low as 3 by the 23rd. That’s flat.
Now, there is a glimmer of hope for the final few days of the forecast. On Monday the 28th of September, the stars finally align. The morning brings a clean 4ft south swell (9 seconds) with glassy conditions and a moderate combined energy of 284. The forecast actually says “expect good surf conditions”. That’s your standout window – the best of the whole run.
The swell builds a bit by the afternoon of the 30th, hitting 5ft from the southeast with a short 7-second period. The combined energy jumps to strong at 516, and it stays glassy again. That afternoon session on the 30th will be packing some punch, but the short period means it’ll be a bit walled up and soft. Still, clean glass and chest to head-high waves? That’s worth a look.
So, overall, you’ve got a long flat spell to ride out, then a solid couple of days at the very end to get excited about. Save your energy for the 28th and 30th of September.

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.
