The Lowdown
Alright folks, Rusty here. Let’s have a good look at the next couple of weeks for our stretch of coast. It’s a bit of a mixed bag, so let’s break it down.
The overall picture is that we’ve got a slow start, a little pulse of energy in the middle, and then a cleaner run at the end of the window. The water is sitting at 74°F and that’s a solid 4°F above normal for this time of year, so it’s noticeably warmer than usual, which is always a nice treat.
The best bet on offer looks like the early session on Sunday, September 6th. We’ve got a clean look to the waves with a 5ft swell from the NW, a 12-second period, and light offshore winds from the west. The energy is moderate at 666, and this looks like the pick of the first week. The other standout is on Wednesday, September 16th. After a bit of a lull, we see a morning with clean conditions and a healthy 5ft of NW swell, also with a 10-second period and glassy winds, with moderate energy at 562. That’s your other good window.
Now, let’s get into the nitty-gritty, day by day.
We start with nothing on Friday morning, September 4th. It’s small, just 2ft and the conditions are poor. The afternoon is the same story. Saturday the 5th isn’t much better, with small, cross-onshore waves and only a questionable afternoon. Forget it.
Sunday morning, September 6th, is where it’s at to start. The waves are up to 5ft from the NW with a 12-second interval, and the offshore wind makes it clean. This is a proper little session for a reef break like this. The energy is moderate at 666. After that, it drops off again quickly, and we’re back to small and messy for the next several days.
From Monday the 7th through to Wednesday the 9th, it's poor. Tiny waves, onshore or cross-onshore winds, and not much to get excited about. Thursday the 10th has a surfable but very ordinary morning, with a clean 4ft from the NW, but it’s nothing to write home about. Friday the 11th gets blown out with moderate onshore winds and rain, so again, no good. Saturday the 12th stays small and uninteresting.
Sunday the 13th sees a bigger but poorly organized swell arrive. We’re looking at 5ft from the NW with an 11-second period, but the northeast wind has it all chopped up. It’s a waste. We stay in a funk from Monday the 14th through Tuesday the 15th, with onshore winds and poor conditions.
Then we get to that standout on the morning of Wednesday, September 16th. This is a solid, clean NW pulse at 5ft with a 10-second period, and the wind is dead glassy, offshore from the east. This will be the cleanest and most powerful the wave will be all window, with moderate energy and some push to it. The afternoon goes onshore, so if you want it, get it early. Thursday the 17th is just ordinary, and Friday and Saturday the 18th and 19th are small and fading, with not enough energy to get the reef working properly.
So, to be straight with you, there are only two real windows worth planning for: Sunday morning the 6th and Wednesday morning the 16th. That’s a long gap in between, so don’t hold your breath for the rest of it. The inconsistency here is a bit of a downer, but when it does line up, it’s worth the wait.
Remember, this is a sheltered reef break, and it doesn't break often. When it does, it can be a gem. This spot is best for beginners, but if the swell is over 5ft, it’s pushing it for the less experienced. With the crowds likely on a clean day, you’ll want to be on it early.
This is Rusty, signing off. Keep an eye on that forecast, it can change.

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.
