The Lowdown
Alright folks, Rusty here, looking at the Asturias surf outlook for the next couple of weeks.
Right, let's get real. The Praia de Asturias is an inconsistent, sheltered beginner spot and the numbers tell the truth. We’ve got a bit of a mixed bag, with a clear standout window early on, and then a whole lot of small, messy days. This is a spot that needs the stars to align, and honestly, for the majority of the 16 days, they don’t.
The best of the bunch is hands-down Friday morning, August 14th. We’ve got a 4ft groundswell rolling in from the SSE with a clean 13-second period, pushing a moderate combined energy of 443. The wind is glassy from the west, which is exactly what you want. That combo will make for some proper clean, fun-sized waves. It’s only small, but it will be the best shape you’ll see all week. The water temp is 70°, and being nearly two degrees warmer than usual for this time of year, it feels nice – a touch warmer than normal, so a spring suit will be plenty.
Saturday morning, August 15th, is the other decent shout. The swell picks up to 5ft from the SSE, still at a long 13 seconds. The combined energy jumps up to a solid 840. And with a dead calm WSW wind, it’ll be glassy again. That 5ft is a bit of a jump for a beginner spot, but for an intermediate surfer, the morning window should offer some clean lines. The afternoon gets messy with a strong onshore wind, so the morning is your only window.
After Sunday the 16th, things get pretty grim. The swell drops, the period shortens to a choppy 8 seconds, and the wind goes onshore or cross-on for days. There’s a long, barren stretch of small, weak, and messy surf – you’re looking at a solid week of poor conditions. We get a brief pulse of knee-high, short-period swell around Friday the 21st and again the following week, but it’s nothing to get excited about. The spot is just too sheltered and inconsistent to handle that kind of weak, short-period energy.
So, here's the call: If you’ve got a longboard and some patience, Friday morning, August 14th is the only real standout. Saturday morning is the next best thing, but it’s a one-session wonder. After that, you might as well leave the board in the car.

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.

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.
