The Lowdown
Alright, this is Rusty. Let's have a look at what's on offer.
Alright, let's be honest, the next week or so is a bit of a write-off for Carcavelos. We've got a long stretch of weak, messy, onshore slop. The water is sitting at 70°, which is a touch warmer than usual for this time of year, but that's about the only thing to get excited about right now. The combined swell energy is barely a whisper (values in the dozens and low hundreds) with short-period, cross-shore winds making a mess of things. You'd be fighting chop and ripples more than riding waves. It's a tough run for a beginner spot like this.
The first real glimmer of hope shows up on Saturday the 25th in the morning. We start to see a pulse of NW swell push through, hitting 5.2ft with a period of 8 seconds. The combined energy jumps to 303 (moderate), and the wind swings to a cross-offshore breeze from the NNW, cleaning things right up. The Saturday morning session is the one to target, but it's still a marginal call, so keep an eye on the tide. By the afternoon, the wind picks up to a fresh 18 mph, which is just too much for a clean wave.
Sunday the 26th is a similar story: a bit of size in the morning at 6.6ft, but the wind is stronger. That's borderline expert territory, and with the wind howling, it's going to be a challenge.
But then, Monday the 27th morning is the standout. The swell drops back to a very manageable 5.2ft from the NNW, the period is 8 seconds, and the combined energy is still solid at 318. The wind goes almost glassy, just a slight 3 mph from the north. That’s a recipe for clean, punchy waves at Carcavelos, and it's the best session in the whole 16-day window. The crowds will be there, as they often are, but for a moment like that, it's worth it.
After that, we fade back out. The week of the 29th onward sees the swell drop away, with small, weak waves and a return of cross-shore winds. The long-range stuff around the 3rd of August shows another pulse of 5.2ft swell, but the wind is pumping at 15-22 mph, so that's more of a kite-surfing setup than a clean paddle session. Overall, a bleak first half, a brief window of clean fun on Monday the 27th, and then slim pickings.

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.
