The Lowdown

Alright folks, Rusty here. Let me level with you straight. I’ve looked over the charts for the next couple of weeks, and if you’re hoping for some real waves at Mundaka, you better pack a book. We’ve got a long, flat spell ahead before anything even thinks about turning on.

The immediate forecast is pretty rough. We’re talking tiny, weak swells, mostly around 1 to 2 feet, with wave energy readings that are barely a blip – we’re seeing numbers in the 40s and 70s, which is just weak. The wind is also all over the place, mostly side or side-on, and that’s going to chop up whatever dribble of a wave does roll through. Classic summer flatness, and it’s going to hang around.

The first real glimmer of hope doesn’t show up until the early morning of Monday, August 17th. The wind finally drops out and we get some glassy conditions. The swell is still small, only about 3 feet, and the period is a weak 7 seconds, but at least it’s clean. The energy is still low, around 91, so it’s not a day to call in sick for, but it might just be enough to get wet and have a few fun ones on the inside. It’s the only time in the first week that looks surfable, so if you’re desperate, that’s your window.

After that, it’s back to the grind. More tiny surf, more onshore junk. The days start to blur together with nothing but flat, weak conditions. You’ll see the combined energy values scraping the bottom of the barrel, dropping into the teens and 20s on the 19th. It’s a real dry stretch that looks like it’s going to stick around for the better part of a week.

Now, here’s the light at the end of the tunnel. We’re looking at a change on the horizon. On Saturday, August 22nd, the energy starts to pick up. The morning shows a glassy 3 foot wave, but the combined energy jumps to 136, which is a moderate bump. It’s still small, but there’s finally some push behind it. The real standout, though, is looking like the morning of Monday, August 24th. The morning is glassy again, and the swell is up to a full 4 feet from the NW. The combined energy is reading a solid 225, which is a proper step up. It’s not a giant, but it’s the best looking window in the whole period. The period is around 8 seconds, so it’s a bit short and won’t have the power of a groundswell, but after this long flat stretch, it’ll feel like a bomb.

The afternoon of the 24th sees the wind pick up and turn side-on, which will mess things up a bit, so the call is the early session. It’s a long way out, but it’s the one to circle on the calendar.

So, that’s the story. A long, drawn-out lull, then a promising but distant pulse around the 22nd and really the 24th. Keep your expectations low for the next week, and start getting excited for that last Monday.

Signing off, 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.

Mundaka is 2 km (1 miles) from Bermeo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Bermeo. Bermeo has rooms for a wide range of budgets as well as car hire and transport links.
