The Lowdown

Alright, Rusty here, and let's have a look at what the charts are telling us for the next couple of weeks. It's a bit of a mixed bag, but we've got some moments worth paddling out for.

The first bit of the forecast period is pretty quiet. We're looking at a few days of small, weak waves and a lot of "poor surf conditions" flags. There's a bit of a ramp-up towards the end of the first week, but don't expect a blockbuster. The main event for the whole window is shaping up around Saturday the 5th and Sunday the 6th, but even then, it's not a perfect picture.

Let's start with the standout, which is Mutriku. This is an inconsistent reef break, so when it lines up, it's a special thing. The best opportunity is going to be on the afternoon of Saturday the 5th. We've got a solid NW swell coming in around 5 ft, with a very long period of 13 seconds – that's pure groundswell with some serious energy. The combined energy is strong at 758, so it's got some grunt. This long-period stuff really suits a reef like Mutriku. The wind is light and from the east, giving it a cross-on angle, which isn't perfect glass, but it's manageable. The water temperature is sitting at 74°, which is a massive 4° warmer than normal for September – a real anomaly, and it’ll feel like a warm bath. The tide and conditions are "marginal," but this is the biggest, most powerful swell of the whole outlook. For a spot that’s inconsistent, this is the one to circle.

Saturday morning, the 5th, is also worth a look. The swell is smaller at 3 ft, but that long 11-second period (combined energy of 310) from the NW will still offer some nice shape. The wind is glassy from the ESE, so it'll be clean, but the waves are just going to be smaller.

Moving into Sunday the 6th, the swell drops a bit by morning. We've got a 4 ft NW swell with a 12-second period (494 energy) but the wind picks up from the NW, putting it on a cross-shore angle. It's doable but not as clean. By the afternoon, it gets a touch bigger at 6 ft and 11 seconds, pumping out 970 energy, but the cross-shore wind is stronger at 15 km/h (9 mph), so it'll be a bit of a chop battle. That's getting into expert-only territory for the size.

After that, from Monday the 7th onward, the energy really drops off. There's a long lull. Monday morning the 7th is completely flat with a 3 ft swell and glassy conditions, but it's just not very good. The next notable blip is not until over a week later, on Tuesday the 16th of September. We get another NW groundswell, 4 ft at 11 seconds with 358 energy, and it's glassy in the morning. That could give a few rideable waves, but it's nothing like the Saturday before.

Tuesday the 15th has a pulse of 102 energy, but it's small and blown-out, and the 18th of September has a similar story with a glassy 3 ft swell. In short, if you're surfing Mutriku, the absolute call is the afternoon of Saturday the 5th. It's inconsistent, so you have to make the most of it when it shows up. For the rest, it’s mostly small and ordinary.

Stay stoked,
Rusty

Information about the Mutriku Surf forecast

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

Mutriku is 16 km (10 miles) from Eibar. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Eibar. Eibar has rooms for a wide range of budgets as well as car hire and transport links.
