The Lowdown
Alright, Rusty here again, let's talk about what's cookin'. The first week and a half is looking pretty bleak, with a lot of messy, choppy conditions and onshore winds. We’re looking at a big dry spell from the 2nd all the way through the 13th of August. Don't bother paddling out; it’s a waiting game. But, stick with me, because the second week has a couple of golden windows.
The first break we get a nod for is Carcavelos on the morning of Friday, August 14th. That’s more than a week out, but the forecast is promising. We’re expecting a clean 5ft swell from the NNW with glassy conditions – the wind is dead calm and the surface will be like a mirror. The water temp is nothing unusual for August. Swell energy is solid at 245, but with a short period of 6 seconds, it’s not a pure groundswell, so it’ll be a bit bouncy and lack that heavy grunt. Still, head-high plus waves with zero wind? That’s a dawn patrol mission for sure. This spot can get busy (says "often"), so get in early.
The absolute standout of the whole 16-day run is Saturday morning, August 15th. Again at Carcavelos. We’re looking at a 6ft NNW swell with perfect, glassy offshore wind from the east – literally no wind at all. It doesn’t get any cleaner than this. The combined energy is 285, and with the swell a bit over 5ft, this is for the more experienced surfer; it’ll be too much for a beginner. The short 7-second period means it won't be the most powerful groundswell ever, but in these perfect, clean conditions, the waves will be peeling and well-shaped. Get on it before the wind changes that afternoon.
Bottom line: the first half of the forecast period is a write-off. Don't even look at your board bag until the second week. Circle Thursday morning, August 14th, and definitely Saturday morning, August 15th at Carcavelos. Those are your two chances at some world-class, clean surf.
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.
