The Lowdown
Alright folks, Rusty here. We’ve got a bit of a slow burner ahead. The start of this 16-day window is pretty flat, so don’t rush down there just yet. The first proper chance for a wave comes on Thursday the 20th of August, but it’s not until Thursday afternoon that things start looking up.
The standout session across the whole run will be that Thursday afternoon, the 20th of August, at Playa de San Lorenzo. We’re looking at a clean 5ft swell from the NNW with a decent 10-second period. The wind goes glassy, dead calm, so the surface will be like a mirror. It’s a fairly exposed spot, so it’ll pick up that moderate wave energy (469), and it’s been consistent here. It’s a solid choice for intermediate surfers. The water temp is about average for the time of year.
Things hold through Friday the 21st, but it gets a bit messy. The swell height bumps up to 6ft from the NNW, but the wind swings cross and cross-onshore, making it choppy. The energy is up there (762–962), but the quality drops off. If you’re an experienced surfer, the early Friday morning might offer a few, but it’s not the clean pick.
After that, there’s a long quiet spell. From Saturday the 22nd right through to Wednesday the 26th, the swell drops away to 0.7ft–5ft. The energy is low (between 24 and 264), and the conditions are a mix of glassy but weak, or bumpy and cross-on. Not worth paddling out for.
We get a little bump of hope on Thursday the 27th and Friday the 28th. The swell sits around 4ft–5ft from the NW, but it’s tangled up with onshore and cross winds. The best chance in that stretch is Friday morning the 28th of August. We get 4ft from the NW, 9-second period, and dead calm glassy conditions. That could actually be a very clean, fun little session if you’re not chasing anything big. It’s a good secondary pick.
The final week is mostly poor. Small swell, short period (5–9 seconds), and not enough energy to get excited about. A few clean windows on the 29th and 30th of August, but the swell is only 4ft–5ft and the wind often spoils it.
If you want the best of it, keep your eye on Thursday afternoon the 20th of August and maybe Friday morning the 28th. Everything else is either flat or blown out.
Rusty.
