The Lowdown

Alright, let’s get real about the next couple of weeks.

Honestly, mate, it’s a bit of a slow grind ahead. We’ve got a stretch of small, messy surf that’s going to test your patience. The water’s sitting at a touch warmer than normal for this time of year, so at least you won’t need the thickest suit, but you’ll be hunting for any kind of decent wave.

We start off this Tuesday with a bit of a dud. The swell’s only around 3ft, coming from the south with a period of 10 seconds, and that’s giving us weak energy, only 158 in the tank. It’s surfable but very ordinary, and the light cross-offshore wind will keep the surface clean at Praia de Asturias. But honestly, it’s not going to get the heart racing.

Wednesday and Thursday are write-offs. The swell drops a touch, but the wind swings onshore and picks up, especially Thursday with 15 mph winds from the east, and it’s just going to be poor, bumpy conditions. You’re better off staying on the beach with a coffee than paddling out into that.

We get a little reprieve on Saturday morning. The wind goes glassy and the swell bumps up to about 4ft from the ESE. It’s still short-period stuff at 7 seconds, but it’s clean and surfable. The energy is moderate at 165, so you’ll get a few soft, crumbly waves, perfect for a beginner on a foamie. It’s ordinary, but at least it’s not a total disaster.

Then we go quiet again. For the rest of the first week and into the next, it’s a whole lot of nothing. Tiny swells, sub-3ft waves, weak energy readings that hover in the 40s and 50s. You’re looking at a solid seven-day drought with no real recommendations. It’s one of those periods where you’d have to be a die-hard to even bother getting in the water.

The only glimmer of something different is late on the 29th of September. The combined energy jumps to a very strong 714, which means the ocean is going to have plenty of push. Swell height is around 4ft to 4ft, but the period is a long 14 seconds, which is proper groundswell. The problem is, it’s coming with a cross-onshore wind and the swell direction is from the SSE, which isn’t ideal. The long period might make it break a bit straight on our beach and reef setup. So, there’s power, but it might be a bit of a mess. It’s promising from an energy point of view, but a long way out, so don’t book your flights just yet.

The last day of the month, Wednesday the 30th, sees some of that energy lingering, but the swell drops back to 3ft. It’s a bit of a tease, a reminder that the ocean’s still there but not ready to commit.

So, bottom line, there’s not much to get excited about. If you can, that Saturday morning is your best bet for a clean, small-wave session. Everything else is either too small, too windy, or just too messy to be worth it. For the more experienced crew, that last Tuesday in September could have some grunt, but it’s likely to be a battle against the wind and some long-period inconsistency. It’s just one of those stretches where you wait for the next proper swell to fill in.

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.
