The Lowdown

Alright, grab your board, let's talk surf. Flat spells are part of the game around here, and for the next several days, that’s exactly what we’ve got. We’re looking at a long stretch of small, weak, and generally unimpressive waves through the first week. The energy just isn't there. But hang tight, because the back half of the window starts to show some real promise.

First up, things are pretty quiet. From Sunday the 16th of August all the way through to Friday the 21st, it's a real struggle. We're talking tiny, weak surf with hardly any push. The combined energy is barely registering, often under 100, and with cross-shore winds and a cross-chop on the Sunday afternoon, it's a write-off. The Monday morning of the 17th shows a brief moment of glassy 2ft SSE swell, but it's so ordinary that there's no real reason to paddle out.

We hit a proper gap of no recommendations until we get to a real standout: Saturday the 22nd of August. That morning at Praia Tenório, the ocean wakes up. The swell jumps to 4ft from the south, with a solid 11-second period. The combined energy is a solid 381, and the real kicker is the wind: dead calm, glassy conditions. The water’s a touch warmer than normal at 72°F, which is always nice. This is the one. The swell direction (S) is right on the money for this fairly exposed spot, and it’s a fairly consistent break, though crowds can pop up sometimes. This is the best session on offer, no question. The Sunday morning (23rd) is also clean and glassy with 4ft south swell at 12 seconds, offering another good session if you miss Saturday.

Then the weather turns. Monday the 24th brings onshore rain and a messy, short-period 6ft south swell that’s blown out and choppy. Not worth it. The real gem of the long-range is Tuesday the 25th of August. The morning session is an absolute standout for the experts. We’ve got 6ft of SSE groundswell with a very long 12-second period, and the combined energy is thumping at 1082, meaning strong wave energy. The wind is glassy calm – offshore from the WSW – and the forecast says "expect very good surf conditions." With swell over 5ft, this is getting too big for beginners, and at 6ft, it's a size where only the experienced crew will feel at home. The long period and south direction are perfect for a spot like this. It’s a cleaner, more powerful day than the 22nd, but it’s raining. From there, the surf fades again through the end of the month, dropping back to tiny, weak conditions with poor surf calls into the 31st.

So the takeaway? It’s a slow start, but the weekend of the 22nd and 23rd offers clean, fun waves for everyone, and Tuesday the 25th delivers a real powerful, clean groundswell for those with the skills and a rain jacket.

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.
