The Lowdown

Alright, this is Rusty. Let’s talk about what’s on the table for Carcavelos.

Right now, the outlook is a real mixed bag. The first few days are pretty flat and ordinary, with small, short-period lumps and breezy cross-off winds that keep things messy. The water temp’s sitting about average for this time of year – nothing unusual there. The first real glimmer of hope comes Saturday the 15th August, but there’s a catch. The swell jumps up to a solid 8 ft from the NNW with moderate energy (947), and the winds are cross-off. That’s a clean look, but this break is beginner-friendly and at that size it’s gonna be too big and powerful for most. It’s really only for the experienced crew. The period is short, only 8 seconds, so it’ll be a bit lumpy and fat, not a classic groundswell.

Sunday the 16th August morning is the standout of the first week. You’ve got 8 ft NNW swell with moderate-strong energy (997), and the wind is a light northerly at just 3 mph, making for clean, glassy conditions. That’s a beautiful combo – clean surf and some heft to it, but again, that size is pushing it for the regular punter. Monday the 17th August morning carries that goodness with 7 ft and *glass* conditions – wind is calm, easterly at 3 mph. The waves will be clean and lined up, though the period’s still short at 9 seconds. It’s still in that ‘too big for beginners’ zone. If you’re advanced and can handle it, Monday morning is your pick.

After that, the surf drops off fast. Tuesday the 18th through the rest of the week turns marginal – smaller swell, onshore or cross-onshore winds mushing things up. Not worth chasing. There’s a gap of several days where it’s just poor surf and honest conditions.

Then, into the second week, things get promising again. Tuesday the 25th August morning sees a nice clean-up: 6 ft from the WNW with a 9-second period (481 energy) and a light NNW cross-off breeze. That’s solid, surfable waves for intermediate and above – no longer too big, and the wind will groom it nicely. The swell direction is right in the wheelhouse for Carcavelos, which likes WNW. That morning is the highlight of the entire 16 days – good size, clean, and the break will handle it well.

Crowds are often an issue here, so expect company on the good days. The break is fairly consistent, so when it’s on, it’s on.

Bottom line: This week is for confident surfers only on a couple of mornings, but come Tuesday the 25th August, it’s game on for a much wider crew.

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.
