The Lowdown
Alright, Rusty here. Let’s break down the next couple of weeks at Mutriku.
The start is a bit quiet. First chance is Sunday afternoon, September 6th, with a 4ft NW swell and a cross-shore breeze, so it’ll be a bit bumpy. The combined energy is moderate at 420, but it’s a marginal call. The water is at 74°, which is much warmer than normal – that’s a nice touch.
Monday morning the 7th looks cleaner. Swell drops to 4ft from the NW, but with glassy conditions, it’ll be smooth and fun. Not a standout for size, but a good session without the chop. Combined energy is moderate at 338.
The one to circle is Tuesday morning, September 15th. We’ve got a 4ft NW swell, 12-second period, and glassy, calm conditions. Combined energy is a solid 435 (moderate), and it’s forecast for good surf. This is a quality window for Mutriku’s reef – clean, well-shaped, and worth getting in the water for.
Keep in mind, Mutriku is an inconsistent, sheltered reef, and it needs a NW swell, which we’re getting. But there’s a lot of poor conditions scattered through the rest of the period, with cross-on or onshore winds and smaller swell. The morning of the 13th of September also offers a clean, small session with a 3ft swell and 13-second period, cross-off wind, and moderate energy at 303 – good for a longboard.
Overall, don’t expect non-stop waves. Pick your windows, and that Tuesday morning is the best of the lot.
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.
