Right then. Rusty here. Let's have a look at what's on the cards for the Lisbon coast, specifically Carcavelos.
Straight up, this is a bit of a weird one. For the next week and a half, we’ve got a whole lot of nothing. The swell is tiny, the winds are messy, and it’s just not worth paddling out. We’re looking at a long, flat gap from now through to about the 16th or 17th of July. Honestly, after Wednesday the 9th, it's pretty much a write-off until the second week.
Alright, fast-forward to Sunday the 19th of July. This is where things get interesting. The models are showing a proper pulse of NNW swell building in. The morning of the 19th sees it roaring in at a solid 6 ft, with a period of 7 seconds from the NNW. The combined energy is a hefty 417, which is moderate energy but the wind is holding cross-offshore from the NNW at 19 mph. That’s a proper clean wind for Carcavelos. The afternoon on the 19th pushes it up to 7 ft, with the combined energy jumping to 534. The wave comment says wind and tide are favourable, but the swell might be getting too big for this break. For a beginner spot, that bump in size is a flag. It’s still a standout, but only for the crew who know what they’re doing.
Then the 20th and 21st of July get properly heavy. We're talking 8 ft from the NNW on Monday the 20th, with a combined energy of 986 (strong) and a period of 8 seconds. The wind is still cross-off. The wave comment repeats the same line: wind and tide favourable, but the swell is predicted to be too big for this break. The same deal for Tuesday the 21st, with a combined energy hitting 1033 and swell holding at 8 ft. This is expert-only territory. If you don't have serious experience, give this a miss.
So where’s the best of it? The standout is that Sunday the 19th of July. That 7 ft NNW groundswell with the cross-off wind is the best set of conditions we have on the menu. Even the morning session on the 19th could be a winner if you pick your moment. After that, it’s a beast for the brave lads only.
Talking about the water, it’s running at 69°F with an anomaly of 2°F, so pretty much bang on average for July. No surprises there.
Alright, that’s the picture. It’s a slow burn, but the second week lights up proper. Stay tuned.
Rusty.

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.
