The Lowdown
Alright, I’m looking at the forecast for Mundaka, and I gotta be straight with you — it’s a tough start. For the next week and a half, the swell is way too small, the wind is pushing onshore, and the energy just isn’t there. The first real glimmer of something rideable doesn’t show up until the morning of Tuesday, July 28th, and even then, it’s a very ordinary day. The swell is only 3ft from the NW, with a period of 9 seconds, and the combined energy is moderate at 173. The water is warm, around 75°, which is much warmer than normal for this time of year — that’s a very unusual spike, more than 3° above average.
Now, the real story comes at the end of the month. Thursday the 30th of July is the standout. You’ve got a solid 8ft NW swell rolling in, with a period of 10 seconds in the morning, building to 12 seconds by the afternoon. The combined energy is strong to very strong (1150 in the morning, 1919 in the afternoon). That’s serious power. The wind goes light and offshore (NNW) in the afternoon, which will clean things up nicely. But listen — this is Mundaka, a river mouth, expert-only wave. At 8ft, this is for experts only. Beginners, stay on the beach. The swell direction from the NW is exactly what this spot wants.
The 31st of July (Friday) is still solid, but a little wind-affected. 8ft NW swell, 11-second period, with a cross-shore breeze in the morning (WNW at 9 mph) and a cross-onshore in the afternoon. Combined energy is still strong (1327 in the morning, 990 in the afternoon). It’s still good, but the Thursday morning and afternoon window is the cleanest and most powerful.
After that, it drops off fast. The 1st of August sees the swell fading to 5ft, with a cross-shore wind and moderate energy (398). It’s not the same quality.
So, to boil it down: you’ve got about a week and a half of flat, frustrating conditions, then a short, punchy window of very good, expert-level surf on the 30th and 31st of July. The Thursday the 30th is the best bet — that clean, offshore afternoon session could be special. But don’t book your trip for it, because long-range forecasts can change. For now, it’s a waiting game.

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.
