The Lowdown
Alright folks, Rusty here. Let's break down what's on the menu for the next couple of weeks.
We’ve got a solid run of surf starting now, but it’s a short-lived window before things go quiet. The main event is definitely the next few days, with a moderate, long-period groundswell from the SSE rolling in. The water is sitting at 73°, which is much warmer than normal for this time of year, so you might not need a full suit.
The pick of the bunch is Praia Tenório on Wednesday morning, August 12th. We’ve got a clean 5ft SSE swell on the cards with glassy conditions. The combined energy is moderate (718), and the offshore wind from the NE will have those lines looking tempting. It's a beginner-plus spot that's fairly consistent, so it should be a fun, uncrowded session.
The run continues strong into Thursday, August 13th. The morning session at Praia Tenório is glassy again with a 5ft SSE swell and moderate energy (801). The afternoon gets even better though, with the same 5ft swell pushing in from the SSE, but with a longer period of 14 seconds and glassy conditions. The energy is still moderate (862), and it’s one of the best windows in the whole outlook.
Friday morning, August 14th, is still worth a look with a 4ft SSE swell, an offshore breeze from the N, and clean conditions. The energy dips to 608, but it’s still a solid option. Saturday morning, August 15th, also has a 5ft SSE swell with a clean cross-off breeze from the ENE, moderate energy (749), and should be a good session.
After that, we hit a dry spell. The swell drops right off from Sunday, August 16th, onwards. The energy levels fall to weak (164 and below), and the wave heights shrink to under 3ft. We’re looking at a stretch of poor to ordinary conditions from the 16th through to the 21st of August, with only a tiny bump of 3ft on the 21st afternoon that’s still rated as poor.
Things only start to hint at a return around Saturday, August 22nd, with a 4ft SSE swell on the morning and glassy conditions, but the energy is still weak (222). It’s a “surfable” but not exciting. The outlook then fades out again into mostly poor conditions through to the end of the period. A small, long-period 2ft SSE swell with 16-second period pops up on Wednesday, August 26th, afternoon, with moderate energy (392), but it’s marginal with onshore wind.
So, to sum it up: get on it now. The next few days, especially Wednesday through Saturday morning, are your best bet. After that, park the board and wait for the next pulse.
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.
