The Lowdown
Alright, Rusty here. Let's talk about what's coming up for Mundaka. The early part of the window is a real struggle. We've got some tiny bumps but nothing worth paddling out for until things change around Saturday the 5th.
That Saturday morning the 5th is your first real standout. A clean 4ft NW groundswell, with a very long period of 15 seconds, pushes in with a light cross-offshore breeze. The energy is moderate (481). This is proper Mundaka, that long period makes for those grinding, drawn-out lines off the point, though it can get a bit straight at the river mouth on a really long period like that. It's an expert wave on a good day, and it's breaking consistently. Water's sitting at 73°, which is a touch warmer than normal for the time of year.
The swell drops back off, and a lot of the following week is plagued by poor conditions and cross-onshore wind. Sunday the 6th has a bit more size at 4ft but it's choppy and messy. You get a small clean window on Monday morning the 7th with an almost glassy 3ft wave, but it's still ordinary.
After another quiet spell, the next chance to keep an eye on is Wednesday the 16th of September. The morning shows a 4ft NW swell with a period of 11 seconds and a slight cross-shore wind. The energy is moderate (322) but the forecast is marginal due to tide. It's a gamble.
And right at the tail end of the forecast, Friday the 18th of September morning looks clean with a glassy 2ft wave. It's small, surfable but ordinary.
So, the best of the whole 16-day run is without question that Saturday the 5th. Be ready to move on it.
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.
