The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
First thing’s first – the water is sitting at 71°F, which is a touch warmer than normal for this time of year. Bit of a bonus, it’ll feel nice.
We’ve got a fair bit of waiting to do, because the first real chance for a surf doesn’t come until Tuesday morning, the 25th of August. Even then, it’s not a barnstormer. The best action is actually going to be on Wednesday the 26th, so let’s get into it.
Sunday the 23rd has a few small, glassy waves in the morning, but it’s ordinary. Not worth paddling out for. Monday the 24th gets a bit of a bump in size with 6ft swell from the SSE, but a 12 mph onshore wind from the ESE will chop it up. The energy is strong (1241), but the wind is a killer. One to skip.
Tuesday morning, 25th August – Now we’re talking. Praia de Asturias gets a glassy start with a 5ft swell from the south. The period is a very long 14 seconds, so this is proper groundswell. The energy is strong (767). The wind is dead calm, so it’ll be clean. This is a good session, but it’s the calm before the main event.
Wednesday, 26th August – This is the standout. The morning session is glassy again, with a 5ft swell from the SSE. The period is a massive 16 seconds, which is about as long as it gets. The energy is very strong (1208). This is expert territory for size, but the conditions are looking prime. The wind swings to a light cross-offshore in the afternoon, keeping it clean. If you can only go once, this is the day. For a spot that’s inconsistent, this is a cracking little window of quality.
After that, the surf backs off. Thursday the 27th offers a clean 4ft swell in the morning (822 energy), but it’s a step down. Friday the 28th has a tiny 3ft leftover with a short 8-second period. Not worth it.
The second week is a mixed bag of small, weak, and often wind-affected waves. The 2nd of September (Wednesday) has some offshore wind from the NW, but the swell is only 3ft with weak energy (162). Surfable, but nothing to get excited about. The 4th of September (Friday) has a 4ft south swell, but it’s onshore. A kite surfer might find it more fun than a paddle surfer during that period.
So, for the paddle surfer, it’s a slow start, one killer Wednesday, and then a long, quiet stretch. Remember, this spot is inconsistent, so a blank run is normal. Forecasts can change, but right now, make the most of that Wednesday the 26th.
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.
