The Lowdown
Alright, Rusty here again. Let’s talk about Praia de Asturias in feet and degrees.
The pattern is the same: a slow, messy start, then a clean window mid-next week before it dies out completely.
Friday 21st and Saturday 22nd August are pretty poor. Small, choppy waves, nothing to get excited about.
Sunday morning the 23rd of August is your first real option. Wave height is around 4ft from the South, period 10 seconds, and it goes totally glassy – dead calm wind. The energy is weak (combined energy 227), so don’t expect power, but it will be smooth and rideable. A real “surfable but ordinary” sort of morning.
The absolute standout is Tuesday morning, 25th August. We’ve got a clean 5ft swell from the SSE with a 14 second period. That’s real groundswell energy (combined energy 824). And the wind? Glassy, out of the NNE at just 3 mph. This is your session. Clean lines, proper push.
Keep in mind, that long-period SSE swell can get a bit straight at the beach, but with absolutely no wind, it’s going to be well overhead and holding its shape. It’s too big for beginners, but for anyone with experience, it’s the pick of the whole 16-day window.
Wednesday morning the 26th also offers clean 3ft South swell at 12 seconds (energy 515) with glassy conditions. Thursday morning the 27th repeats the formula: 4ft SSE at 14 seconds, glassy (energy 526).
From the 28th of August onward, it’s a long, flat spell. Wave heights drop under 3ft, the period shortens, and the wind turns messy. Not worth looking at.
The best session: Tuesday morning, 25th August. The runner-ups are Sunday 23rd, Wednesday 26th, and Thursday 27th mornings – but only if you want a smaller, glassy wave.
The water is warm, about 72°F, which is over 4°F warmer than average for this time of year. A shorty or boardshorts will do you fine.
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. If you surf the same spot (Praia de Asturias) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
