The Lowdown

Alright, this is Rusty. Let’s have a look at what’s coming down the line at Praia Tenório. You’re looking at a slow start, no way around it. The first week is pretty flat and quiet, with a real dry spell through the first few days. Then things start to build, and there’s a clear standout window in the middle of the forecast.

Right now, Tuesday the 18th, we got tiny 1-foot SSE swell with a 10-second period, and it's glassy with zero wind. But honestly, the energy is weak – the combined swell energy is only 21. There’s nothing to ride. The water’s sitting at 71°, which is a touch warmer than normal for this time of year, so at least it’s not freezing just standing there. Wednesday 19th and Thursday 20th are even smaller, with heights dropping to less than half a foot. Don’t bother. Friday 21st shows a brief pulse of 3-foot S swell, but the period is only 4 seconds, so it’s junky and onshore. Still no go.

We get a bit of a lift late on Saturday 22nd, with 4-foot S swell and a longer 10-second period, but it’s onshore wind and the setup looks marginal. The combined energy is 333, so there’s some push, but the conditions aren’t there. Sunday 23rd morning is glassy with 3-foot S swell, and that’s surfable but ordinary. The energy is 177, so just okay.

Now, here’s the big moment – Monday 24th afternoon. The wind drops to glassy, dead calm, and we get 5-foot S swell at 13 seconds. That is a proper groundswell, with combined energy hitting 824. This is the best on offer. The waves will have shape and power, and it’ll be clean as a whistle. This is a standout session for intermediate and above. The swell direction is S, and the guidance says this break likes swell from the south, so it should line up nicely. Crowds can be an issue here sometimes, but on a Monday afternoon it might be a little quieter.

Tuesday 25th morning keeps the good vibes going with 6-foot SSE swell, 13-second period, and a clean cross-offshore breeze from the ENE. Combined energy is 903 – that’s strong. Good for experienced surfers, but at 6 feet it’s too much for beginners. After that, things drop off. Tuesday afternoon gets crosswind at 15 mph, ruining it. Wednesday 26th and Thursday 27th are back to small, ordinary glassy waves – 3 feet and 2 feet, with energy falling below 100. Not worth planning around.

The rest of the run from Friday 28th onward is flat and weak, with occasional tiny bump from southerly swells under 3 feet, but poor conditions and low energy. There’s nothing exciting in that second week. Even early September only shows a modest bump to 4 feet on Wednesday the 2nd, but with short 6-8 second period and cross-shore wind, it’s messy.

To sum it up: the standout is Monday 24th afternoon and Tuesday 25th morning. That’s your window for good, clean, proper surf. Everything else is a wash. Get out there when it’s good, and don’t waste your time on the flat days.

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.
