The Lowdown
Alright, Rusty here, checking in with the local surf outlook for the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week is a write-off. Seriously, from this Monday the 20th through Friday the 24th, we're looking at a total flat spell. The swell is tiny, mostly around 2ft to 4ft, and the wind is just cross-shore junk. The water is a touch warmer than normal for this time of year, sitting at 71°, but that's about the only positive. The wave energy is weak (101).
Now, things start to get interesting on Saturday the 25th. We get a bit more size, with swell pushing 5ft to 7ft from the NW, but it's still a bit messy. The real story is Sunday the 26th. Carcavelos is looking at a solid 7ft swell from the NNW, with clean conditions and a cross-offshore wind. The wave energy is pumping (552), but here's the catch – at this size, 7ft, it's starting to get a bit much for beginners. The forecast says it's potentially too big for this break. For the experienced crew, it's gonna be a proper session.
But hold on. The absolute standout is Monday the 27th. I'm talking about glassy conditions. That's right, early morning on the 27th we have a 3 mph easterly offshore wind, making the surface like a mirror. We've got a 6ft swell from the NNW, with moderate energy (535). This is the best combo of clean, punchy waves we're going to see. The crowd factor at Carcavelos is "often" busy, so get there early for the dawn patrol.
After that, the surf stays in the 5ft to 8ft range for the rest of the week, but the wind goes onshore, making it choppy and messy again. The end of the month and into the first week of August looks like it's going to be pumping, but it's a long way out. The swells are forecast to be over 8ft from the 30th of July onwards, which is strictly for the experts. The wave energy readings are massive – 1195 on the 31st of July – but it's all about being confident with the long-range forecast.
For now, circle Sunday the 26th for a solid session, and definitely Monday the 27th for the cleanest, glassiest waves of the outlook. It's not looking like a consistent run, but when it comes, it'll be worth the wait.

A general guide to surfing at Carcavelos can be found by selecting the local surf guide option on the grey menu.

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.
