The Lowdown

Alright folks, Rusty here, checking in with the long-range look for our local zone. Let's be straight with you – it’s a pretty lean run coming up. We’ve got a long stretch of poor conditions ahead before a window opens up, so get ready to wait.

The first spot on the radar is Menakoz (Biscay). This is an expert-only reef break, and for the next week and more, the stars just aren't aligning. The water is sitting at 75°F currently, which is much warmer than normal for this time of year, a real tropical feel for the Atlantic.

For the first few days, from the 18th right through to the 25th of August, we’re looking at tiny, weak energy. The combined swell energy is in the doldrums, barely cracking triple digits (12 to 104 units), with swells under 3 feet. The winds, while sometimes light, are mostly cross or onshore, churning up the surface. It’s just not worth paddling out.

We get a slight bump in energy on the 26th with a 6 ft swell (216 units), but it’s coming with a 16 mph cross-onshore wind, turning it into a choppy mess. Still no good.

Then, things get interesting for a moment. On the morning of Thursday the 27th of August, we finally see a proper pulse. The combine energy jumps to 784 units, pushing in a 7 ft groundswell from the NW. This is the standout of the whole outlook, a solid size that'll get the blood pumping. Critically, the wind is glassy light offshore from the SSE. That’s the magic combination for a reef like Menakoz: solid NW groundswell with clean, light offshore breezes. Just keep in mind, this is a peak morning window. The afternoon sees the wind shift onshore, and by Friday the 28th, while the swell is still around 4 ft, it’s back to an ordinary, clean but weak state.

After that, from Friday afternoon through to the 2nd of September, we sink back into a pattern of weak swell and average to poor onshore winds. Swell energy drops back below 400 units, and the chop returns. There are no other worth saving graces on the calendar.

So, to sum it up: the first week and a half are essentially a write-off. The one and only true moment of excitement is the Thursday 27th morning session at Menakoz. If you’re an expert and can read a reef, that’s where you want to be for a solid, clean window. For the rest of us, it’s a waiting game. The blank run is pretty normal for this part of the world in late August, but forecasts can change.

Keep an eye on the sky, lads.
Rusty.

Information about the Menakoz Surf forecast

The above surf forecast table for Menakoz provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Menakoz can be found by selecting the local surf guide option on the grey menu. Our Menakoz 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 (Menakoz) 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 Menakoz 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.

Menakoz is 7 km (4 miles) from the city of Getxo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Getxo. Getxo has rooms for a wide range of budgets as well as car hire and transport links.
