The Lowdown
Hey folks, Rusty here. Let me break down what's on the table for the Carcavelos stretch. It's a bit of a flat spell to start, so don't be in a rush to grab your board just yet.
We're looking at a long, quiet run from now through the end of July. The first real hint of something happening doesn't show up until Saturday, July 25th, with a couple of sessions that are barely worth a look. The water temp is sitting at 68°F, which is about average for this time of year, so no surprises there.
The whole first week is a write-off. From Thursday, July 16th right through to Friday, July 24th, it's all tiny, weak waves with poor conditions. The swell is mostly under 3 ft, the energy is pitifully low (often under 100), and the wind is a mess of cross and cross-on directions. You'll be staring at a lot of flat, choppy water. It's a proper drought.
Then, on Saturday, July 25th, we get a flicker of life. The morning sees a 6 ft swell from the NNW, with moderate wave energy (349) and clean, cross-off winds. It's a marginal call, but it's the first thing that isn't a total dud in over a week. The afternoon is bigger but gets blown out by a stronger breeze.
The real standout, and I mean the one that makes you sit up, is way out on Friday, July 31st. This is a long-range call, so don't bank on it, but the numbers are wild. The morning shows an 8 ft swell from the NNW with a long period of 12 seconds, and a massive combined energy of 2293. The wind is light and offshore from the NE, which would make Carcavelos clean as a whistle. But here's the catch – 8 ft is expert territory, and the file says it might be too big for this break. The afternoon is similar, with an 8 ft swell and 11-second period, but the wind turns cross-shore. For a beginner-friendly spot like Carcavelos, this is strictly for the experienced crew who know the lineup. That's your one true standout, but it's a big, powerful, and uncertain one.
For the rest of the second week, from Sunday, July 26th through Wednesday, July 30th, we're back to small, weak surf with mostly clean but unproductive conditions. The energy is low, and the swell is barely a ripple. Nothing to get excited about.
So, to sum it up: a whole lot of nothing for the first 10 days, a brief, marginal window on the 25th, and then one big, expert-only promise on the very last day of the month. Keep your eyes peeled on that 31st, but don't hold your breath.
Rusty.

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.
