The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Praia Tenório.
Right off the bat, we’ve got a window that’s worth paddling out for. Tuesday the 8th is your first real chance, and it’s a beauty to kick things off. The ocean is putting on a show with a nice 4 ft south swell, rolling in with a 10-second period. The water’s sitting at a comfortable 73°, which is a touch warmer than normal for this time of year—nothing drastic, just a little extra warmth in the air. What really makes it special is the absolute glassy conditions, not a whisper of wind. That’s the kind of morning you dream about. The combined energy is moderate, clocking in at 270 (moderate wave energy), so there’s enough push to get you moving without it being a fight. The swell direction is right out of the south, which is exactly what this break likes to see. You’ll want to get on it early because crowds are sometimes a factor here, but with conditions this clean, it’ll be worth sharing a few waves. Tuesday afternoon still has glassy surf, but the wave height drops a fraction to 3 ft, and the rain showers might put a bit of a damper on the vibe.
Wednesday the 9th is a step down—still glassy in the morning with a smaller 2 ft SSE swell, but the energy drops off (108, moderate wave energy), and the session feels more like a recovery paddle than a highlight. The heavy rain in the afternoon doesn’t help, even if the wind goes offshore.
We hit a bit of a quiet patch from Thursday the 10th through to Saturday the 12th. The swell sticks around the 2 ft to 3 ft range, and while the period stretches out nicely on Thursday and Friday (12–14 seconds), giving those waves a bit more shape and punch for a south swell, the conditions get sloppy on Saturday with cross-onshore winds and a short period of 5 seconds. Not worth getting too excited about.
Now, here’s the standout you’ve been waiting for. Sunday the 13th, first thing in the morning, brings a solid 5 ft south swell with a 10-second period, and the combined energy jumps right up to 408 (strong wave energy). That’s a proper surge of power. And it’s glassy again. No wind, clean lines. This is the best session on offer. The swell size is just on the edge of being too big for beginners—over 5 ft it starts to get spicy—but for anyone with a bit of time in the water, it’s a ripper. The crowd situation? Sometimes busy, but with conditions this good, you’ll take it.
Sunday afternoon, the wind swings up to 15 mph from the ESE and the surf gets chopped. Not the same story.
Monday the 14th has a fresh cross-shore breeze and lumpy conditions, not your friend. The swell is still there at 4 ft, but the quality’s gone.
Tuesday the 15th and Wednesday the 16th are small again—2 ft to 3 ft—with clean spells on Wednesday morning and afternoon, but nothing that sets the heart racing. The energy is low to moderate (62 to 190).
Thursday the 17th sees a jump in swell height to 5 ft, but it’s coming in with a cross-onshore wind and only a 9-second period, and the energy is 322 (strong wave energy). The conditions are choppy and poor. A bit of a tease.
From Friday the 18th onwards, we’re into a long tail of small, average surf. Friday morning has a clean 3 ft south swell with 238 (moderate wave energy), but by Saturday the 19th morning it’s patchy, and Sunday the 20th drops to 2 ft. The rest of the outlook—from the 20th through to the 23rd—is mostly tiny swell under 3 ft, with glassy periods but not enough power to get excited about. There’s a gap of essentially no real recommendations from Sunday the 20th onward, just little knee-high bumps. The final days on the 22nd and 23rd show a small return to 3 ft–3 ft with clean conditions, but it’s more of a longboard cruise than a standout session.
So, to wrap it up: your two best windows are Tuesday morning the 8th and Sunday morning the 13th. Both deliver a decent south swell with glassy conditions and moderate to strong energy. The Sunday session has the edge on power. Get out there when you can.
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.
