The Lowdown
Alright folks, Rusty here. Let’s see what we’ve got for the Lisbon stretch over the next couple of weeks.
Honestly, looking at the whole 16-day window, I gotta say it’s a pretty quiet run. There’s nothing that’s going to have you ringing in sick to work. The first week is mostly small and weak, with a few days where the wind cleans things up, but the energy just isn’t there to make it worth paddling out. There’s a stretch from the 3rd right through the 9th where the surf is either poor or just plain weak. We finally see a bit of a bump in size around the 6th and 7th, but the quality is still lacking.
The standout, if you can call it that, is Thursday the 6th and Friday the 7th. On Thursday morning, Carcavelos is seeing a 5 ft swell from the NNW. The wind is a clean cross-offshore breeze, so the lines will be tidy. The combined energy is moderate at 478, but the period is a short 9 seconds, so it won’t have much punch. Still, for a beginner beach break, it’s probably the most surfable you’ll see. Don’t expect barrels, but it’ll be rideable. Friday morning is similar at 6 ft from the NNW, but the energy is a bit lower (341) and the wind is a bit stronger. It’s a marginal call, but if you’re desperate, that’s your window.
The water temperature is about average for this time of year, so no need to worry about a wetsuit thicker than a spring suit.
After the 7th, it drops off hard. The 8th and 9th are tiny, and then the second week from the 10th onwards is a total write-off. We’re talking knee-high slop with very weak energy levels – mostly under 100. The 11th has a long period, 11 seconds, from the NNW, but the swell height is only 1 ft, so it’s just a tease. The 14th and 15th see another bump to around 6 ft, but the wind is moderate and cross-shore, chopping it all up. Not worth the paddle.
Basically, if you don’t get out on the 6th or 7th, you’re waiting for a miracle. The consistency is fair, but the quality is poor. Looks like a good time to clean the wax off your board.

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.

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.
