The Lowdown
Alright, Rusty here, let's talk about what's cookin' for Mutriku.
Right off the bat, we're lookin' at a bit of a tough start. The first few days are a write-off with messy winds and weak, short-period chop. We gotta sit tight through that early part of the week. The water's sitting at 73°, which is much warmer than normal for this time of year – a nice little surprise if you're not wearing a full wetsuit.
The real spark lights up on Saturday morning, September 19th. This is the standout. We've got a solid 7ft groundswell pumping in from the NW with a nice 13-second period, and the wind is glassy. Flat calm. The combined energy is pumping at 1430, so there's plenty of power in the water. This is the one you wait for. The offshore wind for Mutriku is from the SSW, and this swell is from the NW, so it's gonna wrap in nicely. Keep in mind, this is a sheltered reef that's inconsistent and can get crowded sometimes, so get in early and pick your sets.
Sunday the 20th keeps the fun going with glassy 5ft surf, but it's a step down in size. Then we hit a bit of a lull through Monday and Tuesday before a sneaky good call on Wednesday morning, September 23rd. We've got another glassy morning with a long-period 5ft NW swell at 14 seconds. The energy is back up to 1109, showing it's got some grunt. That's a promising mid-week window.
After that, it's a mix. Thursday the 24th looks okay, but Friday drops off. Saturday the 26th has a very long-period 16-second swell but with tricky onshore winds, so it won't be clean. Sunday the 27th starts glassy again with a clean 5ft, but the wind goes nasty in the afternoon.
Lookin' into the first few days of October, Monday the 28th has tricky conditions, but Tuesday the 29th morning is a real highlight for the second week. We've got a solid 7ft NW swell, 11-second period, and a clean offshore wind. The energy is 1045. This is well overhead, a proper session for experienced surfers. Wednesday the 30th has a cleaner morning, but the swell is smaller.
So, keep your eyes on Saturday the 19th morning and Tuesday the 29th morning. Those are the ones to circle. The rest is a game of pickin' the glassy windows.
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.
