The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty flat and quiet for us. If you're itching to get wet, you're going to have to be patient. There's a big gap of nothing worthwhile right through until the morning of Wednesday, September 16th.
Let's start there. The best chance we get in this whole window is the morning of Wednesday, September 16th, at Praia de Asturias. We've got a tiny 3ft swell rolling in from the SE, but the real story is the wind: it's dead glassy. Zero wind. It’ll be clean as a whistle. The water temp is sitting at 71°, which is a touch warmer than normal for this time of year, so that's nice. Don't expect much power though – the combined energy is weak at 163. It's small, but it's the cleanest you'll see.
After that, it's more of the same small stuff until the morning of Friday, September 18th. That morning also looks good, with another glassy session. We're looking at a 3ft swell from the south, with a period of 13 seconds, which gives it a bit more shape. The combined energy jumps to a moderate 462. It’s still not big, but glassy conditions on a 3ft south swell? That's about as good as it’s going to get. A proper little session for the log or a fun mid-length.
The rest of the period is a write-off, honestly. Lots of onshore winds, short period wind swell, or just too small to bother with. There's a bit of a pulse around Sunday, September 13th, with 5ft swell but it's a short 8-second period and onshore wind – that'll be a messy crumbler at best.
So to sum it up: if you want a surf, wait for the morning of the 16th for the small glassy stuff, or the morning of the 18th for the best combo of size and clean conditions. Otherwise, save the gas.
Rusty.

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 Praia de Asturias 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.
