The Lowdown

Alright, Rusty here, checking in on the Mundaka forecast. We've got a tricky outlook for the next couple of weeks, but there are a couple of windows where it could get really good.

The problem is the start. For the first few days, the wind is just wrong for the river mouth. It’s a lot of cross-on or cross-shore wind messing up a decent NW groundswell. The water is a balmy 73°, which is over 4° warmer than usual for this time of year, so the trunk is feeling good even if the waves aren't.

Monday the 14th is a write-off with that cross-on wind and a weak 3ft NW swell. Tuesday the 15th is a bit bigger but lumpy. Wednesday the 16th looks like it might turn on-shore, and the swell is too short-period for Mundaka's magic.

Now, Thursday the 17th is where we start to see some life. The swell picks up to 5ft from the NW with a solid 11-second period. The wind is a light breeze, even if it's cross-on. It's a big step up from the junk before it. By Friday the 18th afternoon, we get a 4ft NW swell with a very long 16-second period. The wind stays light cross-on. It’s still not perfect, but the potential for a clean wave is there.

The real standout for the first week is Saturday the 19th. We’re looking at a solid 7ft NW groundswell coming in at a 13-second period. For most, that’s a heavy, expert wave. The wind is still cross-on from the ENE, which is a shame because it could be epic. It’s going to be big and powerful, so only for the experienced crew.

After that Saturday peak, the swell backs off a bit but the wind looks to clean up nicely. Sunday the 20th, the morning session is looking glassy with a light offshore from the SSW and a clean 4ft NW swell. That’s the kind of window where Mundaka does its best work. Monday the 21st looks even better for the early crew. Glassy to clean conditions, a 5ft NW swell with a 12-second period. That is a great window for a left-hander that just reels.

We get another taste of it on Tuesday the 22nd morning, with glassy conditions and a solid 4ft NW swell. After that, from Wednesday the 23rd into the weekend, the swell really drops off. The wave energy gets weak, and we’re looking at mostly small, poor conditions.

The last hope comes on Friday the 25th. We get a clean morning with a 4ft NW swell and a 12-second period. The wind is a light cross-off from the SSE, which is a great sign for the wave shape. It’s the last decent pulse in a very up-and-down run. After that, it goes flat again.

So, to be honest, if you can only pick one or two sessions, Sunday the 20th morning and Monday the 21st morning are your best bets. Clean, workable swell and the river mouth should be firing. Saturday the 19th is the biggest, but only if you've got the stones and don't mind the side-wind.

Keep an eye on it, the long-range stuff is always a bit of a gamble, but the signs are there.

Rusty.

Information about the Mundaka Surf forecast

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