The Lowdown
Alright, Rusty here. Let's talk about the surf coming up.
We’ve got a bit of a slow start, but there’s a solid run of surf on the horizon for Praia Tenório. The first couple of days are pretty quiet, but from Saturday the 22nd, things start to wake up. The water is sitting at 73°, which is much warmer than normal for this time of year – a real treat.
The first real standout is the Saturday morning session on the 22nd. We’re looking at a clean 5ft S swell with a period of 11 seconds, and the wind is glassy. The energy is strong for this spot, with a combined energy of 451. It’s got that weekend feel, and with the break being fairly consistent, it’s going to be a good one. Just keep in mind that crowds are possible here.
Then, the real highlight of the whole outlook is the Tuesday morning on the 25th. This is the one to circle. The swell is up to 6ft from the SSE, with a very long period of 14 seconds, and the wind is glassy. The combined energy is a meaty 1464, and the conditions are described as excellent for experienced surfers. This is a proper groundswell, and while the long period might make it a bit straight at the beach, the size and the clean glassy surface will have the juice. It’s a bit of a wait, but it’s the best on offer.
The Sunday morning on the 23rd is also a nice little runner, with a 4ft S swell and glassy conditions. The energy is moderate at 282, so it’s a smaller, more relaxed option. The Wednesday morning on the 26th and the Thursday morning on the 27th are also worth a look for a clean, glassy session with fun 4ft and 5ft swells, respectively.
After that, we hit a lull from the 28th through to the 2nd of September. The swell drops right off, and the conditions get poor. It’s a solid week of very small waves or poor wind, so don’t bother checking the forecast during that stretch.
The surf picks up again on the 3rd of September. The Thursday afternoon shows a 6ft SSE swell with a clean cross-offshore wind. The energy is a solid 583, and it’s fairly consistent. Not as perfect as the 25th, but a solid option for the second week.
The Friday morning on the 4th of September is another promising one in the long range. A 4ft SSE swell with a very long period of 14 seconds and glassy conditions. The energy is 694. It’s a bit of a wait and a bit less certain, but it has the makings of a very good session.
For the beginner crew, the Saturday morning on the 22nd is the best bet. The swell is 5ft, which is manageable, and the glassy wind will make it easy. The 4ft Sunday the 23rd and the 5ft Thursday the 27th are also good options for you. The 6ft on the 25th is too big, only for the experienced crew.
Overall, the first week has some real gems. The Tuesday the 25th is the standout. Keep an eye on that Friday the 4th of September session, too.

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.
