The Lowdown
Righto, let’s talk about the next couple of weeks for Praia Tenório. We’ve only got this one break on the radar, so we’re going local. The water’s sitting at 73°F – a touch warmer than normal for this time of year thanks to a 3°F anomaly, so it’s pleasant.
The week starts off flat and messy, to be honest. Monday morning brings light rain and a little 3ft south swell, but the cross-off wind keeps it clean enough for a paddle. Energy is low though – only 119 (weak) and the period is short at 8 seconds. Nothing to get excited about. By Monday afternoon, the wind goes glassy and the swell picks up a touch to 147 (still weak), but still those same 3ft waves. It’s surfable, just ordinary.
Tuesday gets a bit more interesting. The afternoon sees the swell bump to 4ft from the south with a 10-second period, and it’s glassy. That energy jumps right up to 431 (moderate). This is the first real standout of the forecast. The south swell direction matches what this spot likes, and with glassy conditions you’re looking at clean, fun waves. It’s a small window though – by Wednesday morning we’re back to 2ft and glassy again, but with low energy (165).
Wednesday afternoon turns ugly: onshore wind from the SSE, 3ft, and a longer 12-second period that’ll likely close out the beach. Not worth it.
Thursday gets blown out with a strong cross-shore wind at 12 mph, leaving a chop. Even though the swell is 3ft to 4ft with moderate energy, the conditions are poor. This one’s a skip.
Friday morning on the 18th of September is where I’d point you. Glassy conditions, 3ft from the south with a 12-second period, and 284 energy. That’s clean, decent shape, and the wind is your friend. It’s the best-looking session of the first week. The afternoon gets a bit of a cross-on breeze, so morning is the call.
From Saturday the 19th onward, the swell drops right off. We’re looking at 2ft and lower for the next four days, with weak energy (down to as low as 9). Plenty of glassy mornings, but barely a wave worth paddling for. That gap lasts until around Tuesday the 29th, but don’t hold your breath. There’s a small pulse on Monday the 28th – 2ft from the south with an offshore wind, but it’s ordinary.
Tuesday the 29th brings the last notable event: a glassy morning with 4ft from the SSE, period 8 seconds, energy 225. It’s surfable but nothing special. The afternoon blows up with a 5ft short-period swell (7 seconds) and a cross-on breeze, which is only really for strong swimmers or kite gear.
To wrap it up: Tuesday 15th afternoon is the standout – glassy, 4ft south swell, good energy. Friday 18th morning is second best with clean 3ft. After that, it’s mostly flat or blown out. If you’re keen, hit those windows.

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.
