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, we’ve got a slow start. The first few days are pretty flat and ordinary, with only tiny, weak 2ft to 3ft SSE swell and very low wave energy. Honestly, unless you’re desperate for a paddle, it’s not worth getting wet Friday through Sunday, September 4th to 6th. The wind is messy on Saturday afternoon and Sunday is a write-off with 12 mph onshore winds and a short, lumpy 7ft S swell that’s just junk.
Now, Monday morning, September 7th, things start to turn. We’ve got a clean 6ft SSE swell pushing in from the south-southeast, and the wind is dead calm, glassy. The combined energy is solid at 610 (moderate wave energy), and the period is a decent 10 seconds. That’s a proper groundswell, and with glassy conditions, Praia Tenório will be fun. The water temperature is about average for this time of year, so no worries there. That Monday morning session is the first real standout in this outlook.
Tuesday the 8th drops off again with smaller, croaky swell and cross-shore winds, so not great. Wednesday the 9th has a brief window of clean, offshore wind in the afternoon but only 2ft, so you’ll be hunting for a knee-high ripple.
Then we hit another quiet spell. From Thursday the 10th right through to Sunday the 13th, the swell is tiny, mostly under 3ft, with weak energy and poor conditions. There’s a brief blip of 3ft from the SW on Saturday afternoon but with a 4-second period, it’s just wind chop.
The next real bright spot is Tuesday, September 15th. Early morning brings a clean 4ft SSE swell with a light offshore breeze from the north – that’s clean, lined-up waves. The energy is moderate at 280, and it’s a short period (8 seconds), so it’ll be a bit more punchy and crumbly, but still fun on a longboard or a fish. The afternoon holds up well too, with a clean 4ft SE swell and cross-offshore wind. That Tuesday is your best bet for the second week.
After that, the swell fades again. Thursday the 17th afternoon has a glassy, long-period 3ft S swell (14 seconds) with a lot of energy (375), but it’s a long period, so it might be a bit straight at the beach, but still clean. Friday the 18th morning is glassy but small at 2ft. The rest of the run is pretty forgettable.
So, if you’re picking a session, Monday morning, September 7th is the clear winner – decent size, glassy, and good energy. Then Tuesday, September 15th is your second-best call, with clean offshore winds and a fun little swell. Everything else is either too small, too windy, or just plain ordinary.
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.
