The Lowdown
Alright, Rusty here. Let's talk about the coming weeks for Mundaka.
Honestly, looking at the next 16 days, it's a bit of a grind. The forecast is mostly showing small, wind-affected swell and poor conditions. We're looking at a long stretch of nothing special, with the best action likely a full two weeks out, on the 19th of September. That's a long wait for a glimmer.
The only real standout is the morning of Saturday, the 19th of September. We've got a clean, glassy Northwest swell running at about 4 feet, with a period of 10 seconds. The combined energy is moderate (304). The wind is barely a whisper from the WSW, so it's going to be clean. For an expert spot like Mundaka, that's your window. It's not a huge swell, but the conditions will be near perfect. If you're after a barreling left, that's the session to pencil in.
The morning of Tuesday, the 8th of September, is briefly worth a mention. A tiny 2.5-foot WNW swell with glassy conditions. The energy is low (146), so it's not going to be pumping, but it might be the only clean ankle-to-knee-high wave you get for a while.
The rest of the period is messy. There's a spike in swell on the 9th of September, with 8 feet of NW, but it's short-period (8 seconds) and hammered by a 15 mph cross-onshore wind. That's a choppy, dangerous mess. After that, the wind is mostly cross or cross-onshore, making most of the smaller swells unsurfable. The water temp is about average for this time of year, nothing to worry about.
So, for the die-hards, there's a date on the 19th. For everyone else, wait for the forecast to change.

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.
