The Lowdown
Alright, Rusty here, let's talk about what's happening in the water.
Honestly, this stretch is a tough one for the Mundaka crew. The forecast is a flat spell, plain and simple. We're looking at a long, dry run with almost nothing to get excited about. For the first week and a half, the swell is tiny and the conditions are just messy. We’ve got a long gap of poor surf ahead, with no real recommendations coming through until the second week.
From Wednesday the 29th of July through to Thursday the 6th of August, it’s all very small surf, mostly below 3ft, and the wind is a problem. It’s consistently cross-on or onshore, chopping up what little bump there is. The combined energy is weak, with values mostly in the 30s, 40s, and 50s – nothing with any punch. There are a few glassy moments on the morning of Friday the 31st of July and Saturday the 1st of August, but the swell is barely 2ft to 2ft with a short period, so it’s not doing anything. It’s a frustrating time.
Then on Friday the 7th of August morning, we finally see a little pulse. The swell bumps up to 3ft from the NW, with a short period of 6 seconds, and the wind goes glassy. The combined energy is still only 81, so it’s weak, but it’s the first surfable moment in over a week. The river mouth at Mundaka might have a few crumbly 3ft to 3ft waves, but it’s not the classic barrel. It’s just “surfable but very ordinary.”
The best of a bad bunch looks like Thursday the 13th of August. The morning is glassy, with a 3ft NW swell and a 9-second period. The combined energy climbs to 129, which is the highest we’ve seen in the whole forecast. Winds are calm, so it’ll be clean. That’s your standout window, but it’s a long way off, so keep your fingers crossed. For an expert spot like Mundaka, this is a waiting game. The forecast can always change, but for now, don’t bother paddling out until that second week.
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.
