The Lowdown

Alright, this is Rusty checking in on the surf outlook for the Lisbon area.

Alright, let’s be real with you. The next 16 days are looking pretty grim around here. We’ve got a long stretch of poor surf conditions, with only a few very brief windows that might be worth a look. The water temperature at Carcavelos is sitting at 68°, which is close to normal for this time of year, so at least you won't be freezing.

The only real standout in this whole period is a brief window early on. Monday morning, the 17th of August, we get a bit of a break. The swell is 6 ft from the NNW, but the big news is the wind. We’re talking a glassy, 3 mph offshore from the SE. That’s clean. The period is a short 8 seconds, so it won’t have much punch, but for a beginner-friendly spot like Carcavelos, it’s the cleanest you’ll see. The combined swell energy is moderate at 364.

After that, it’s a wasteland. The wind goes onshore or cross-shore, the swell drops, and the quality tanks. There’s a bit of a bump in size on the 21st of August (Friday) with a 10-second period, but the wind is too strong from the NNW, making it marginal at best. The 30th of August has some size again, but it's a cross-shore chop.

Honestly, for the next two weeks, if you want to paddle out, that Monday morning is your only real shot. The rest of the time, the conditions are just poor. The wind just doesn’t play ball for us.

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.
