The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Mundaka over the next couple of weeks.
We kick off with a bit of a slow start, but don't let that fool you. The first real standout is shaping up for Thursday, the 10th of September. The morning of the 10th is where it's at. We’ve got a clean 4ft swell rolling in from the NW with a period of 11 seconds, and the best part? Glassy conditions with a light WSW wind. The water is sitting at 73°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit. The combined energy is moderate at 328, so there’s a bit of push behind it. This is the pick of the run, a real chance to get some clean, lined-up waves off that famous river mouth.
After that, things get a bit messy with onshore winds and poor conditions until we get another window. Sunday morning, the 13th of September, also looks promising. Again, we’re looking at a glassy morning with a 3ft NW swell, period of 10 seconds, and light WNW airs. The combined energy is 306, so similar to the previous standout. It’s a little smaller, but the clean conditions will make it very user-friendly for those who know the break.
There’s a long gap of poor conditions after that, with the next glimmer of hope not until the 20th of September. That Sunday morning looks clean with a cross-offshore wind and a 3ft NW swell, but it’s very ordinary and not the same quality as the earlier windows.
Overall, the 10th and 13th of September are the sessions to pencil in. The rest of the period is largely a write-off with too much onshore wind or simply not enough energy. Keep your eyes on those glassy mornings.
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.
