The Lowdown

Alright folks, it’s Rusty here, and I’ve got the lowdown on the local surf scene for the next couple of weeks. Let’s get straight into it.

First up, the big picture: we’ve got a bit of a mixed bag. The early part of the forecast is a real struggle, with a lot of poor conditions and no real standout sessions. The water is hanging around a touch warmer than normal for this time of year, with a reading of 71°F at the start, so a wetsuit might feel a little extra toasty.

We start with a bit of a flat spell. The first few days are a write-off, honestly. Sunday the 23rd and Monday the 24th are a mess, with onshore winds and poor surf. The swell is there, but it’s just not working. On Tuesday morning the 25th, we have a 5ft SSE swell at 14 seconds, but with a cross-onshore wind, it’s just not clean. It’s a no-go.

Then things start to look up. Wednesday the 26th is the first real glimmer of hope. Early morning at Praia de Asturias, we get glassy conditions with a light 3 mph wind from the southeast. The swell is 4ft from the SSE, but the period is a very long 16 seconds. That’s a proper groundswell, and it’s got a combined energy of 886 (moderate). That long period will make for some beautiful, lined-up waves, but it’s a point break or reef setup that’ll really shine; a beach break might see it a bit too straight. Still, for a morning surf, that’s the pick of the early window.

Thursday the 27th morning is also a solid option. Clean, cross-offshore winds from the southwest, with a 5ft SSE swell at 14 seconds. The energy is 834 (moderate). It’s not the biggest, but clean conditions make it very surfable.

From Friday the 28th through to the end of the month, it drops right off. We’re looking at small, weak swells and mostly onshore or cross-shore winds. The combined energy falls into the double digits, with readings like 97 and 78. It’s pretty small and ordinary. The first week of September is similar, with a lot of small, weak energy and poor wind.

But hold on – there’s a standout in the long-range. On Thursday the 3rd of September, we’ve got another glassy morning. The wind is dead calm from the east-northeast at 3 mph. The swell is 5ft from the SSE at 11 seconds, with a combined energy of 502 (moderate). That’s a clean, fun-sized day. It’s a week and a half away, so keep an eye on it, but it’s the best bet for a proper session in the second week.

After that, it’s back to small stuff and onshore winds. The whole run is a bit of a waiting game, but that Wednesday the 3rd looks like the one to circle.

Rusty out.

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.
