The Lowdown

Alright folks, Rusty here. Let's have a look at what Carcavelos has got cookin' over the next couple of weeks.

Right off the bat, it's not a great start. We're looking at a bit of a wait. The first few days are a write-off with messy, onshore winds and junky little windswells. Wednesday the 9th and Thursday the 10th are basically a no-go. We gotta put in the time.

Friday the 11th morning finally shows a flicker of hope. It’s not big, with a 5ft swell from the NNW, but periods are short at 7 seconds. The wind is switching to a light NNE cross-off, so it'll be clean, but it's not going to win any awards. The wave energy is weak (267), so keep your expectations in the "fun little logger" range.

The real standout in the first week looks like Sunday the 13th morning. The wind goes glassy from the ESE, and we’ve got a pulse of longer period groundswell coming in. It's only 3ft, but that NW swell has a 13-second period, which gives it some real grunt. The combined energy jumps up to a moderate 389. That's the session to point the car towards if you want clean, lined-up walls. Carcavelos is an exposed beach, so that long period will help keep things from closing out completely, and the glassy conditions will make it feel a lot better than the size suggests.

After that, the middle of the week gets a bit average again with building cross-shore winds and dropping swell. We get another clean window on Saturday the 19th morning. The NE wind goes glassy and there's a solid 4ft NW groundswell with an 11-second period and a combined energy of 436. That's a proper session for a confident surfer – clean, good energy, and just a fun size.

Now, for the real kicker. Monday the 21st and Tuesday the 22nd are looking huge, but there's a massive catch. We're talking an 8ft to 10ft NNW swell, with combined energy readings going through the roof (1544). The model is screaming "too big for this break." This is expert territory only, and honestly, with that much power hitting an exposed beach like Carcavelos, it's gonna be a washing machine. It's the kind of day you sit on the dune and watch, or maybe take a kite out if you're that way inclined.

But hold on, because the tail end of the forecast is where the magic is. Wednesday the 23rd morning is looking like the pick of the entire run. We're down to a 6ft NW swell, the wind is dead calm and glassy from the ENE. The energy is a solid 604. It's clean, it's manageable, and it's all there for the taking.

Then, Thursday the 24th morning is another absolute gem. A long-period 6ft NW groundswell, period pushing 12 seconds, with glassy conditions from the NW. Combined energy at 791, that's proper juice. That is the morning to clear your schedule. It’s going to be clean, powerful, and with those long lines, perfect for Carcavelos.

So, to sum it up: the first week is a slog with only a few windows. Sunday the 13th and Saturday the 19th mornings are your early targets. For the big stuff, the 21st and 22nd are for experts only. But the real money is on Wednesday the 23rd and Thursday the 24th mornings – those are the standouts.

Rusty out.

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.
