The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this forecast for Carcavelos is a tough one. We’re looking at a long stretch of days where the swell is just too weak or the wind is putting a chop on it. The whole 16-day window is a struggle, but there is a little light at the end of the tunnel.
For the first week and a half, it’s flat or close to it. From Wednesday the 15th through to the 24th of July, we’re looking at tiny waves, mostly under 2 feet, with a lot of cross-shore wind messing things up. The combined swell energy is a measly 43 to 168 (weak to moderate energy), so you’re basically fighting for a knee-high dribble. The water temp is sitting at 68°, which is about average for this time of year, so nothing to complain about there. But honestly, this is a time to leave the boards in the car.
There’s a glimmer on the morning of Wednesday the 22nd – the surf report says "surfable waves but very ordinary conditions" with a clean face and a 1 foot WNW swell. That’s a maybe, but it’s a long shot. The crowds at Carcavelos are often thick, so don’t expect a quiet session even for that.
Then, things get interesting – and a little scary. The morning of Sunday the 26th of July is our only real standout. The forecast shows an 8 foot swell from the NNW with a period of 8 seconds, and the combined energy jumps to 899 (strong wave energy). The wind is cross-shore, but the surf report says "wind and tide favorable, but the swell is predicted to be too big for this break." That’s a big red flag for beginners. This is expert-only territory. An 8 foot wave on a beach break like Carcavelos is a proper handful, and with that period, it’s going to be a powerful, dumpy wall.
The last few days of the month, from the 29th to the 30th, tease us again. The morning of Wednesday the 29th has a clean, off-shore wind from the N, with a 6 foot NNW swell. The swell energy is 477 (moderate-strong energy), and conditions are called "good." But then the 30th of July morning shows a 7 foot swell with clean cross-offshore wind, but again, it’s flagged as "too big for this break."
So, to sum it up: if you’re a beginner, stay home for the first two weeks. The only real window for a proper, clean surf is the morning of the 29th for the more experienced crew, but that’s a long way off and the forecast could change. For the die-hards, the 30th morning is also a promising one, but it’s big. The rest of the time, it’s a flat spell with a few ripples. Don’t hold your breath.
Rusty.

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.
