G’day, this is Rusty. Let’s have a look at what’s on offer for Carcavelos over the next couple of weeks.
Alright, straight up, the next week and a bit is a bit of a write-off, to be honest. We’ve got a long stretch of nothing much happening until the final weekend of the period. The first recommendation for a surf doesn’t pop up until the 26th of July, which is a solid two-week gap of poor or marginal conditions. The water temperature is sitting around 67°, which is pretty much normal for this time of year, so no surprises there.
From now until late July, it’s a lot of small, weak swell with onshore or cross-onshore winds. The combined swell energy is mostly in the double digits (like 52 to 98), which is weak, and the swell heights are barely knee-high. There are a couple of days around the 18th to the 20th of July where the swell bumps up to 6 ft to 6 ft, but the wind is howling from the NNW at 19 mph, and the period is short (6 to 7 seconds). That’s a messy, blown-out situation that’s more for kites than paddling. For a beginner-friendly beach break like Carcavelos, anything over 5 ft with strong wind is a no-go.
The real standout, the only one worth getting excited about, is the morning of Sunday the 26th of July. Carcavelos gets a clean, glassy dawn with the wind dropping to 3 mph from the NW – that’s glassy, perfect conditions. The swell is a solid 5 ft coming from the NNW, with a period of 8 seconds, and the combined energy is a healthy 368 (moderate energy). It’s not a monster, but it’s a fun, clean size for a beginner to intermediate wave. The direction matches the optimum swell direction from the west, so it’ll be working well. Keep in mind, the crowds are listed as “often,” so expect company out there, but on a clean, glassy Sunday morning, it’ll be worth it.
After that, the afternoon goes cross-shore and choppy, and the following Monday morning (27th July) is marginal, so that Sunday morning window is the one. It’s a promising call, but it’s two weeks out, so keep an eye on the forecast.
Rusty.

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.
