The Lowdown
Alright, let’s switch it over and talk it in feet.
To be honest with you, the next week and a half look pretty grim. There’s a massive quiet spell before anything worth paddling out for shows up. We’re looking at a solid 10 days of poor surf conditions with very little energy in the water. The combined energy figures are mostly well under 100 (weak) and the swell heights just aren't cutting it. The wait is long, but it does look like there’s a light at the end of the tunnel.
The first real glimmer of hope comes in for Thursday, 20th August. Around that time, a slightly more promising window opens up, but it’s not all smooth sailing. The real standout looks like it will be the Friday morning (21st August) session at Mundaka. We’ve got a clean 3-4ft NW groundswell pushing through with a period around 10 seconds and a combined energy of 263 (moderate). The wind early is glassy (W 3 mph), which means it should be super clean. The swell direction is from the NW, which is the optimum direction for this spot. Keep in mind, this is a long-range call so it is promising but not locked in yet. If it comes together, the wait will have been worth it. Just be aware, this break is for experts only and on a good day the crowds are often heavy – but the quality makes it a must-check.
Before that, Thursday morning (20th August) at Mundaka is worth a mention as a warm-up. The swell is a touch smaller at around 3ft but it’s also a groundswell with a very long period of 11 seconds, giving it shape and power (combined energy 242). The wind is glassy from the ENE at 3 mph, so it will be smooth. However, the forecast says “surfable but very ordinary conditions” so keep your expectations set to small and clean rather than pumping.
The main takeaway? The first week and a half are a write-off for any kind of quality wave. The water is running much warmer than normal for this time of year at 75°, which is unusual. Things finally start to look a little more interesting around the 20th and 21st, with Friday morning the pick of the bunch.

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.
