The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the table for the Lisbon stretch over the next couple of weeks.
Honestly, it’s a pretty grim run. We’re looking at a long stretch of nothing much. The first recommendation doesn’t pop up until Sunday, the 2nd of August, and even then it’s only barely surfable. Before that, from the 30th of July right through to the afternoon of the 1st of August, it’s all poor surf conditions with tiny, weak swells and messy winds. A real waste of time. So, a solid three-day gap with no reason to even check the cam.
Sunday, 2nd August finally shows a glimmer of life at Carcavelos. The morning session is the only thing worth mentioning. You’ve got a 4ft swell from the NNW with a short period of 7 seconds, and the wind is a gentle cross-offshore breeze from the NNW, keeping the surface clean. The combined energy is weak at 197. It’s surfable, but very ordinary. The water temp is sitting at 68°, which is about average for this time of year.
The rest of the outlook is a drag. From the 3rd of August through to the 14th of August, nearly every session is flagged as poor surf. The winds are mostly cross-shore or cross-onshore, and while the swell bumps up a little here and there, the quality just isn’t there. The morning of the 7th of August offers another little 4ft window with clean conditions, but again, it’s just ordinary.
The only real standout, if you can call it that, is the Monday afternoon of the 10th of August. The swell jumps to 3ft from the NNW with a 9-second period, but the energy reading hits 305, which is the highest in the whole forecast. The problem? The wind is a fresh cross-shore from the NW at 19 mph, creating a lumpy cross-chop. It’s not clean, but it’s the most juice we’ll see. Then Friday the 14th of August sees the biggest swell of the run, hitting 5ft from the NNW, but with a period of only 6 seconds and a fresh cross-offshore wind. It’s still poor quality.
Bottom line: This is a tough block for paddle surfing. If you’re desperate, the Sunday morning of the 2nd of August is your best bet for a clean, small wave. Otherwise, the 10th of August has the most energy, but you’ll be battling the wind. For beginners, the swell never gets over 5ft, so it’s safe, but the conditions are so ordinary you’ll be frustrated. Honestly, with that cross-shore wind and weak swell, this setup looks more interesting for a kite surfer than a paddle surfer for most of the period.
Stay patient, keep an eye on the charts. It tends not to stay this poor for long.
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.
