The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Cabo Lastres.
Right now, it’s a slow start, folks. We’re looking at a few days of nothing really worth paddling out for. The first couple of days, Wednesday and Thursday, are tiny with poor surf conditions. We’ve got some small, weak swell but the wind is just messy.
Things start to pick up a little on Friday the 21st, with a pulse of 5ft swell from the NNW (moderate energy at 530), but the cross-shore wind will have it looking a bit lumpy and marginal. Saturday and Sunday are even smaller and choppier, so you’re not missing much. There’s a real dry spell here until the following week.
Now, keep your eyes on Wednesday the 26th. That’s our first proper glimmer of hope. The morning session is looking clean, with a light cross-offshore wind and a solid 5ft swell from the WNW (378). This is where the point starts to wake up. It’s a clean setup, and for an expert-level wave like Cabo Lastres, that’s what you want.
But the real standout... the one you circle on the calendar... is Thursday the 27th morning. We’re talking a chunky 10ft swell from the NW, with very strong energy (1934). Now, that’s a big boy wave. The wind is cross-shore, which isn’t perfect, but at this size and with that power, only the experts are going to be out there. This is serious stuff. The water temperature is 73°, which is a touch warmer than normal for this time of year, so you might not need the thickest rubber.
After that, we get another clean spell on Friday the 28th. The swell drops a bit to 5ft, but with a light cross-offshore wind from the ESE, the wave face will be clean. A good, solid day for those who want a slightly less intense session.
Looking further out, the end of August and start of September has some big numbers on the board. The 31st of August and the 1st of September both have 10ft+ swells (very strong energy), but the wind is more of a factor. These are promising but less certain this far out. Then, on Wednesday the 2nd of September, we’ve got another glassy morning with a clean 5ft swell. That could be a beauty if it holds.
So, to sum it up: a quiet start, then a big, expert-only window around the 27th morning, followed by some cleaner, more manageable days. Don't sleep on that Thursday morning if you've got the skills.
Rusty.

Information about the Cabo Lastres Surf forecast
The above surf forecast table for Cabo Lastres provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cabo Lastres can be found by selecting the local surf guide option on the grey menu. Our Cabo Lastres 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.

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 Cabo Lastres 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.
