The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Carcavelos.
Right off the bat, I gotta be straight with you – the next week and a bit is pretty grim. We’re looking at a long, dry spell with hardly any surf worth paddling out for. From Saturday the 1st of August right through to Friday the 8th, it’s mostly small, weak, and messy. The combined swell energy is low, mostly under 200 (97 to 295), and the wind is never truly offshore in a clean, glassy way. It’s mostly cross or cross-off, with a moderate to fresh breeze, so the surface is going to be bumpy. You’ll see some waist-high dribble but nothing with any punch. The water temp is about average for this time of year, so no surprises there.
The first real glimmer of hope comes on Saturday the 9th of August. The morning sees a bump in size to 5ft from the NNW, with a period of 9 seconds and a combined energy of 466. That’s moderate energy, and the wind is a clean cross-off from the NNW. It’s still a bit jumbled, but you could get some fun ones if you’re patient. The afternoon gets bigger, 5.6ft, but the wind picks up to 19 mph, so it’ll get blown out.
Now, the true standout, and the one I’d circle on your calendar, is the morning of Saturday the 15th of August. This is a big one. We’ve got 6.9ft of NNW swell, with a 9-second period and a massive combined energy of 676 (strong energy). The wind is a clean cross-off from the North at 22 mph. However, this is a serious caveat – at 6.9ft, this is expert-only territory at Carcavelos. It’s going to be powerful, and the crowds will be inevitable. If you’re not a solid, experienced surfer, stay on the sand and watch.
Following that, the morning of Sunday the 16th of August looks promising too. The swell drops back to 6.2ft from the NNW (8-second period, 554 energy), but the wind drops right out to a light 6 mph cross-off. That’s clean, glassy conditions, and the size is still solid for a good session. This one is a bit more manageable for strong intermediates.
So, to sum it up: the first week is a write-off. The best bet is the morning of the 15th for the experts, and the morning of the 16th for the rest of you who want a clean, powerful wave. Keep your eye on the forecasts, but that’s how it’s looking right now.
