The Lowdown
Alright, Rusty here. Gotta be honest with you, it's a rough couple of weeks ahead for Carcavelos. A long stretch of nothing to start, then a bunch of junky days. The best shot comes way down the line, so plan for that.
We're starting with a total blank from now until the 9th of August. Nothing of use – just poor and marginal readings. That's a solid four-day gap with no recommendations. Water is 19.4°, average for this time of year.
Finally, on the morning of the 9th, you get a little 2-foot wave from the west with a short 7-second period. The energy is weak at 76. It's surfable, nothing more. A light 9 mph cross-offshore wind from the NNW will keep the surface clean. Fine for a beginner paddle.
From the 10th through the 19th, it's mostly junk. Small surf mostly under 3 feet, short periods, and moderate winds that keep things rough. On the 12th, the ocean energy bumps up, but it's still a messy, onshore situation with a NNW swell. By the 19th, the swell hits 5 feet from the NNW, but with a 22 mph wind, it's just a washing machine.
Here's the one bright spot. Circle the morning of Thursday, 20th August. We get a 5.2 foot swell out of the NNW. The period is short (6 seconds), but the wind goes light and cross-offshore from the NNE at only 9 mph. That's clean. The energy is moderate, and the forecast says good conditions. For a beginner-friendly size, that's your best window. Aim to be out there early; the afternoon wind is gonna mess it up again.
Short Range ForecastMostly dry. Warm (max 26°C on Fri morning, min 19°C on Wed night). Winds decreasing (fresh winds from the NNW on Thu afternoon, light winds from the N by Fri night). | Days 5-7 Weather SummaryMostly dry. Warm (max 25°C on Sat afternoon, min 19°C on Sun night). Wind will be generally light. | |||||||||||||||||||

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.
