The Lowdown
Right, let’s have a look at what’s cooking for Carcavelos over the next couple of weeks.
Straight up, the first few days are a bit of a write-off. We’ve got some small, weak swell and cross-shore winds that are just not making it happen. The best you’ll find is a surfable but ordinary wave on Wednesday morning, 2nd September, with a 4ft swell from the NNW and a short 8-second period, clean enough with a light cross-off breeze, but it’s not going to get the heart racing. The water’s sitting at 68°, which is about average for this time of year, so no shocks there.
We then have a real flat spell from Friday afternoon right through Saturday, with the swell dropping and the wind turning messy. Honestly, it’s a bit of a dead zone for a couple of days.
Now, Sunday the 6th of September is where things start to wake up. The morning brings a clean 4ft of NW groundswell with a solid 12-second period, and the combined energy is a moderate 520. That’s a proper, punchy wave with good shape, and the light cross-off wind will keep it clean. This is the first real standout of the window. The afternoon gets windier though, so hit the dawn patrol.
The following Monday morning, the 7th, sees a bigger pulse of 5ft from the WNW with a long 13-second period, and the energy jumps to a strong 1014. That’s a lot of power in the water. With a clean cross-off breeze, it’ll be offering some excellent, lined-up waves. The size is getting up there, so it’s not for beginners, but for the experienced crew, this is the best call of the whole forecast. The only thing to watch is the onshore wind after lunch.
Tuesday the 8th still has some size at 6ft from the NNW, but the period drops to 10 seconds and the wind is a moderate to fresh cross-off, keeping it clean. The energy is still strong at 905, so there’s plenty of push, but the quality is a notch down from Monday.
We get another gap in the quality through the middle of the week, with the swell dropping and the wind picking up. The surf is either too small, too windy, or just messy.
The next real highlight is Saturday the 12th of September. A clean 6ft swell from the NNW with a light offshore breeze. The energy is a moderate 471, and the 8-second period means it’ll be a bit more sectiony, but with that offshore wind, it’ll be a fun, clean day for those who know the bank.
But the absolute best of the second week, the one to circle on the calendar, is Sunday the 13th of September. The morning has a 5ft groundswell from the NW with a very long 13-second period, and the energy is a very strong 971. The wind is light and variable, offering clean conditions. This is a serious, powerful, offshore swell at Carcavelos. It’s going to be a proper session. The long period does mean it might be a bit lined up and fast, which is a treat for the more experienced surfer.
The outlook then fades out again through the 14th and 15th, with some fun but smaller waves, and then a lot of wind and chop for the final few days.
The standout session is the morning of Monday the 7th of September, with that big, clean, long-period swell. The second best is the morning of Sunday the 13th of September. Get out there for those.

Information about the Carcavelos Surf forecast
The above surf forecast table for Carcavelos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Carcavelos can be found by selecting the local surf guide option on the grey menu. Our Carcavelos 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 (Carcavelos) 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 Carcavelos 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.
