The Lowdown
Alright folks, Rusty here. Let’s get into it for the Asturias region. We’ve got a rough patch of surf ahead, but there are a couple of moments worth paddling out for.
Honestly, right now the ocean’s looking pretty ordinary. We’ve got chest-high 3ft waves from the SSE with a 10-second period, but the water is a touch warmer than usual at 71°. The energy is moderate (221). The glassy wind on Tuesday morning will keep it clean, but the consistency is just not there. It’s surfable, but nothing to get excited about.
Wednesday morning sees a drop in energy to 148, with 3ft from the ESE. The wind is cross-off, so it’ll be clean, but the 8-second period means short, weak waves. Not your best bet.
Thursday brings a 12-second period swell from the south, but it’s tiny at 2ft and onshore wind ruins it. A no-go.
We’re looking at a real dead zone from Friday right through to the following Tuesday morning. The swell is small, winds are messy, and the energy is mostly weak. Not worth a paddle.
Now, Tuesday 15th September morning: a slight improvement. We’ve got 4ft from the SE with a 9-second period. The energy is moderate (253), and the wind is light cross-off, so the waves will be clean. It’s still ordinary, but it’s the best we’ve seen in a while.
Then, Wednesday 16th September afternoon is one of the better windows. The swell bumps up to 5ft from the SSE with a 9-second period, and the energy jumps to 456. The wind is cross-off and clean. This is where the surf actually starts to look decent. It’s a standout, but only for more experienced surfers – that size will be too much for beginners.
The following Thursday morning, 17th September, is glassy with 4ft from the SE, period 8 seconds, and energy of 285. It’s clean and surfable, but not a standout.
After that, it gets messy again. Friday and Saturday look poor, with onshore winds and choppy conditions. The swell on Saturday 19th September hits 6ft from the east, but with a cross-onshore wind, it’ll be a junky, powerful mess. Too big for beginners and only for experts who like a challenge.
The last week of the forecast is a mix of small, weak swells and clean conditions, but nothing that really excites. The energy is low, under 100 on some days, and the waves are small.
The best on offer is definitely Wednesday 16th September afternoon at Praia de Asturias. It’s a beach and reef setup, and the 5ft swell from the SSE with clean cross-off wind will be the most fun you’ll have. The consistency is poor, so don’t expect a set wave every minute, but when they come, they’ll be worth it. Crowds are possible, so get in the water early. This is the one to circle on the calendar.
Rusty.

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