The Lowdown
Alright, let's talk Praia Tenório in feet and knots.
The next couple of weeks are a bit of a slow starter, no doubt. The best early option is Thursday afternoon (the 10th). We're looking at a clean, glassy 2-3 foot swell from the SSE, with a 13-second period that'll give it some decent shape. The water's a touch warmer than usual, sittin' at 73°. The energy is moderate at 219, so it has a little push for a longboard. The crowds are *sometimes* a thing here, so you might have a few buddies out for the small stuff. This spot is good for beginners, and that waist-high glass is perfect for a mellow cruise.
Friday morning (the 11th) has a similar 2-3 foot swell, glassy and clean. By the afternoon, a cross-off wind picks up, keepin' it rideable. Saturday the 12th is tiny and glassy in the morning, but then the swell vanishes and the wind turns onshore. From Saturday afternoon through the 13th, it's mostly poor with bumpy, onshore junk. A few days of total write-offs.
We get a spike on Monday the 14th. The morning brings a 5-foot swell from the SE, but the period is a short 8 seconds, so it'll be a bit sectiony and closing out. The wind is glassy, which is a huge win, makin' it look clean. The energy jumps to 363, so there's some real power there. That's getting a bit too much for beginners; you'll want a step-up board and some experience.
Then we hit another flat patch. Tuesday the 15th morning has a tiny knee-high glassy wave, but that afternoon gets torn apart by a 15 mph cross-on wind. Nothing worth paddling out for.
The real standout is way out there. Thursday the 24th. That afternoon, we get a solid 4-5 foot SSE groundswell with a 12-second period, and it's completely glassy. The energy reading hits 916 – that's a lot of water moving, so you'll feel the pull. The wave comment says "very good surf conditions." That's the day. The swell direction matches what this break likes best, and the long period will bring in clean, powerful lines. It's solid overhead and perfect for experienced surfers.
Friday the 25th morning is another gem: 4-5 foot, 14-second period, glassy, with 629 energy. That's an excellent session, too, but Thursday arvo is the one that stands out above the rest.
So, first week is mostly small and average. The big, clean power doesn't show up until the tail end of the second week. That Thursday the 24th is the one to have circled, but like any long-range call, it's a promise, not a guarantee.

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.
