The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the next couple of weeks.
Right off the bat, the outlook is a tough one for Carcavelos. We’ve got a long stretch of ordinary conditions before anything really gets interesting. The first viable surf we see isn’t until Wednesday morning, July 29th, but it’s not much to write home about. You’ll find a 3 ft NW swell with a 9-second period, and the combined swell energy is a moderate 141. The NNW wind is blowing cross-off, so the surface is clean, but the vibe is just "surfable waves but very ordinary conditions." Not a standout.
Thursday the 30th through the following weekend is a real write-off. The swell drops, the wind picks up, and the scores are low. You’ll see a lot of "poor surf conditions" in the data. The swell energy dips to a weak 19 on Friday morning, July 31st, with a tiny 1 ft WNW swell. Pretty grim.
Saturday, August 1st, shows a slight pulse with a 2 ft W swell, 9-second period, and 101 combined energy, but the morning N wind is light and cross-off, so it’s clean. Still, the conditions are only "very ordinary." Not a day to get excited about.
The real contender doesn’t show up until Monday, August 10th. That morning, we’ve got a 5 ft NW swell, 8-second period, and the combined energy is a strong 381. The wind is a glassy N at 3 mph. That’s rare. The forecast says "expect good surf conditions." This is your best bet in the whole window. The water temp is about average for the time of year, so nothing to worry about there.
However, be careful on Tuesday, August 11th. The morning shows a 8 ft NNW swell with 8-second period and a massive 623 combined energy. The wind is cross-off from the NNW, clean, but the forecast warns that the swell is predicted to be too big for this break. At over 8 ft, that’s expert-only territory, and even then, it might be a washing machine. The afternoon is even bigger with 846 energy and a fresh 19 mph wind. That’s more manageable for a kite than a paddle.
The only true standout here is the glassy morning of Monday, August 10th. That’s the one. For the rest of the run, you’re mostly looking at small, weak, or windy days. The long stretch of poor conditions from July 30th to August 9th is a real gap to get through. But that one Monday morning makes it worth keeping an eye on.
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.
