The Lowdown
Alright, let’s talk about what’s happening at Praia de Asturias over the next couple of weeks.
To be honest, we’re looking at a slow start. There’s some swell around early on, but the conditions are all over the place – small waves, short periods, and the wind is just not cooperating. The water temp is about 71°, which is a touch warmer than usual for this time of year, so it’s not a bad day for a swim if you’re not fussed about waves.
Things start looking up on Thursday morning, August 15th. We’ve got a clean 5ft swell from the SSE with glassy conditions. That’s a morning to get out early – clean, small but fun, and with the combined energy at 648, there’s some real push in the water. This break is a sheltered beach and reef setup, so it handles the swell well. It’s an inconsistent spot, but when it’s working, it’s worth the trip. Crowds are possible, so don’t expect total solitude.
Sunday morning, August 18th, brings a bit more size – 6ft from the ESE, but with a short period of 8 seconds. It’s glassy again, so the surface will be clean, but that short period makes it a bit lumpy and disorganised. The energy is moderate at 700, so there’s some grunt, but it’s not the quality we want. This one is more for experienced surfers as it’s pushing into bigger territory.
From around the 19th through the 23rd, it goes quiet – small, weak swells and poor winds. Not much to write home about. Then, on Tuesday, August 26th, we get a proper pulse: 5ft from the south with a very long period of 16 seconds. The combined energy jumps to 1187 – that’s strong. The winds are clean and offshore. This is the standout for the second week – a real groundswell with serious power. That long period means well-shaped waves, but they might straighten out on a beach break, so the reef elements here will be a plus. It’s a long way out, so don’t bank on it just yet, but it’s got real potential.
Best bet? That glassy Thursday morning the 15th, and the long-period south swell late on the 26th.

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.
