The Lowdown
Alright, grab a coffee and listen up. This is a tough one to call. We’re looking at a 16-day window for Praia Tenório, and honestly, it’s a flat spell with a couple of tiny windows that might just get you wet. Don’t expect much.
The water’s sitting at 70°F which is basically dead average for this time of year – nothing to write home about.
We kick off on Saturday the 18th of July. The morning is the only real highlight in the whole first week. We’ve got a tiny 2ft swell from the SE, with a period of 10 seconds. It’s not much, but the wind is glassy, dead calm from the NW. That’s the key here. The wave energy is weak (79), so it’s for the longboard or a funboard. This is a beginner-plus spot, and the crowd factor is "sometimes," so you might have a few friends out. The combo of glassy conditions and a workable swell direction makes this the best bet of the entire outlook. Saturday afternoon through to the end of the month is grim. The swell drops to 0.6ft or less, period is all over the place, and the energy is almost non-existent. There’s a long stretch of several days here with nothing worth paddling out for.
Now, fast forward. There’s a flicker of hope on the 24th of July, Friday morning. We get a bump in swell to 4ft from the S, with a period of 8 seconds. The energy hits a moderate 228. The wind is glassy, calm. The problem? It’s a short-period swell, which isn’t ideal, and it’s a Friday, so the "sometimes" crowd factor might tip toward "often." Still, it’s the biggest swell of the whole run. The onshore wind kicks in later that day, so the morning is the only window.
Then we go quiet again until the 1st of August, Saturday morning. Another jump: 3ft from the S, period of 9 seconds, and a moderate energy of 220. The wind is glassy again. This is the second-best option. The swell direction is a bit south, and the optimum here is S, so it’s a good match. The following Sunday morning, the 2nd of August, has a similar setup with 2ft and glassy winds, but it’s smaller.
So, to sum it up: The standout is the morning of Saturday the 18th of July. Clean, glassy, tiny but rideable. The backup is the morning of Friday the 24th of July for size, and then the morning of Saturday the 1st of August. Everything else is a write-off. The long-range stuff is promising but not a sure thing.

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.
