The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer for the next couple of weeks around Mundaka.
It’s a bit of a slow start, to be honest. The first few days are a write-off – we’ve got a mix of onshore winds and messy conditions that just aren’t gonna cut it. The water temp is about average for this time of year, so no surprises there.
The first real whisper of hope comes on the morning of Sunday the 13th. We’ve got a pulse of 5ft NW groundswell with a 13-second period rolling in, and the wind is glassy from the SSE. That’s clean, and the combined energy is solid at 613 (moderate wave energy). That’s the standout of the whole run – a proper window of glassy conditions on a decent size swell. It’s still a bit small for the experts only, but Mundaka (river) can handle it fine. Just be aware that it’s an expert wave and crowds are often here.
Monday the 14th morning is also worth a paddle. Glassy again with a light ESE breeze, 4ft of NW groundswell at 12 seconds, and the energy is 392 (moderate). Not as punchy as Sunday, but clean and lined up. The afternoons both days get messy with a NE cross-onshore, so get it early.
After that, it drops right off again. The combined energy sinks into the double digits, and we’re back to poor surf through the middle of the week. The 19th of September shows a glimmer – a glassy morning with 4ft NW swell, but the period is short at 8 seconds, so it’s ordinary at best. The 20th morning is slightly better with 4ft NW swell, glassy, and 10 seconds of period, but nothing to get excited about.
Looking further out, the 24th of September morning has a glassy start with a 3ft NW groundswell and a long 13-second period, energy at 318 (moderate). It’s promising but a long way off, so don’t bet the house on it yet.
Best bet: Sunday morning, 13th September. That’s the gem. Monday morning is a solid backup. After that, it’s a waiting game.
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.
