The Lowdown
Alright, Rusty here, and I’ve been staring at the charts for our neck of the woods. Gotta be straight with you – it’s a tough stretch ahead. We’re looking at a long, quiet spell before anything really moves.
Right now, things are flat. For the first week, from Saturday the 15th right through to the end of Thursday the 20th, it’s a write-off. The energy is weak, with combined swell energy barely cracking triple digits and often sitting in the 50-60 range. Winds are mostly cross or cross-onshore, and the swell is tiny and short-period. Water temp is about what you’d expect for this time of year. Honestly, for the first six days, don’t even bother with the board.
The first real glimmer comes on Friday morning, the 21st of August. Cabo Lastres (Cabo-Lastres) finally gets a pulse. The wind goes glassy, and we see a 4ft swell from the NNW, with a period of 10 seconds. Combined energy jumps to 327 (moderate), which is a decent kick. That Friday morning session is your only real window for a week – clean, glassy conditions, and a proper, rideable swell. It’s not huge, but after a week of nothing, it’s the standout.
But that’s the only real highlight. After that Friday morning, it gets messy again. Saturday the 22nd has light cross-offshore winds, but the swell drops back under 3ft and the energy is gone. Sunday the 23rd through Thursday the 27th is a mix of poor wind and small, weak swell. A couple of days, like Wednesday the 26th, show a bigger swell (4–5ft with 420–574 energy), but the wind is cross-shore and the forecast says marginal. It’s not clean, and it’s not worth the paddle.
The end of the run, around Friday the 28th and Saturday the 29th, gives us a couple of moments. Friday morning is glassy again with a 2ft swell – but it’s small and the energy is only 71 (weak). Saturday the 29th afternoon shows a 5ft, 11-second swell from the NW, with 416 energy, but it’s got a moderate cross-shore wind and it’s labelled as poor conditions. It’s a tease.
So, the big picture: one solid morning on Friday the 21st, and then nothing else that’s really worth chasing. This is a long, dry run for the area. If you’ve got to get wet, that Friday morning is your best bet. Otherwise, leave the boards in the car.
Rusty.

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.
