The Lowdown
Alright folks, Rusty here. Let’s take a look at what Praia Tenório has in store.
Right off the bat, we’re looking at a pretty slow start. The first week is mostly a write-off for any real surf. From Wednesday the 19th through to Friday the 21st, it’s basically flat with poor surf conditions. The water is a touch warmer than normal for this time of year at 71°, but that’s about the only good news.
We finally see a pulse of energy arrive on Saturday the 22nd. The morning shows a glassy surface with a 4 ft southerly swell. It’s surfable, but the combined energy is still only moderate at 247. The afternoon gets a bit better, with the same 4 ft southerly holding and the energy jumping to 347, but the wind swings onshore. Sunday the 23rd cleans up again in the morning with glassy conditions and a 3 ft southerly swell. These are small, rideable days, but nothing to get too excited about – just ordinary conditions.
The real interest kicks off on Monday the 24th. Monday afternoon we see a 6 ft south-southeast swell, and the combined energy jumps into the strong range at 1344. The period is a long 14 seconds, which will bring some proper groundswell energy. This is a standout for the pickings we have, but it comes with a caveat: the wind is a light cross-onshore, so it won’t be perfect. Still, for this break, that’s the best wave size we’ll see for a while, and the energy is serious.
Tuesday the 25th continues with a solid 5 ft southerly swell in the morning and a very long period of 14 seconds. Energy is still very strong at 1067. The wind is cross-shore. This is another one for the experienced surfers. For a beginner, that 5 ft is pushing the limit, and the long period at a beach setup can make it a bit fat and straight. The afternoon drops to 5 ft but the energy and swell direction hold.
Wednesday the 26th and Thursday the 27th are a step down, with smaller 3 ft and 2 ft swells, but the mornings offer glassy conditions. Nice for logging or a longboard, but not for anyone looking for power.
The real standout, and the best on offer in this entire 16-day window, is Thursday the 3rd of September. Thursday morning brings a 5 ft southerly swell with a 13-second period. The combined energy is a very strong 747, and the key here is the wind: it’s glassy, completely calm. The forecast says “expect very good surf conditions.” That’s the day to circle on the calendar. It’s two weeks out, so keep an eye on it, but if it holds, Praia Tenório is going to be clean, punchy, and fun.
For the rest of the run into early September, it’s mostly small and messy.
So, to sum it up: endure the flat spell this week, keep an eye on the pulse on Monday the 24th, but the real highlight is that glassy Thursday morning on the 3rd of September. Get on it if you can.

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.
