The Lowdown
Alright, Rusty here. Let’s get into it for Mutriku. This is a sheltered reef break, so it needs the right direction to fire, and when it does, it can be a thing of beauty. We've got some decent windows ahead.
The pattern kicks off Monday the 31st of August with a real standout. A clean 6ft NW groundswell, with a long 10-second period, is pushing in under glassy conditions. The combined energy is a solid 585, which is moderate but punchy for this spot. The water is a balmy 74.5°, which is much warmer than normal for this time of year. That Monday morning is the pick of the early run – clean, fun-sized waves, and a real treat for a Monday. The wind goes onshore in the afternoon, so get it while it’s good.
The next few days are pretty flat or messy. Tuesday and Wednesday morning have some small, weak swell but the wind is cross-onshore or onshore, making for poor conditions. We drop right off through Thursday and Friday with tiny, weak surf.
Then we get a pulse of juice. Saturday the 5th of September morning fires up again with a 5ft NW groundswell, but this one has a very long 14-second period. The energy is strong at 877. The glassy morning looks clean, but that long period will make it break a bit straight at the reef. It won't be as perfect as the Monday, but it’s a real session. Sunday the 6th morning holds similar energy with a 5ft+ swell and 12-second period under glassy E winds – another good, clean option.
The following week sees a drop-off again, with mostly small, poor-quality surf until we hit the next real highlight. Tuesday the 15th of September morning is a serious prospect. A 6ft NW groundswell with a long 14-second period and a very strong energy reading of 1378, all under glassy offshore WNW wind. This is the biggest and most powerful swell of the whole outlook. The afternoon gets messy with onshore wind, but if you can get on it Tuesday morning, that’s the one to circle on the calendar. The week prior will see a long gap of nothing much, so don't hold your breath until then.
So, the two standouts are clearly Monday morning the 31st for a clean, fun session, and especially Tuesday morning the 15th of September for the biggest, most powerful surf of the run. Get out there.

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.
