The Lowdown
Alright, Rusty here again. Let’s run through the same outlook but in feet and Fahrenheit for you imperial crew.
The opening stretch for Mundaka is a no-go. Saturday the 25th and Sunday the 26th are blown out with cross-shore winds and lumpy, choppy conditions. The groundswell is trying to show up, but the wind is ruining it. The combined energy is moderate (120 to 278), but it’s not worth the paddle.
The first real chance comes on Monday the 27th morning. A 5ft NW swell with a long period of 11 seconds pushes in, and the wind goes light onshore. The energy jumps to 458 (moderate to strong), but the forecast says “marginal” due to tide. Still, it’s a glimmer. The real gold is Tuesday the 28th morning. The wind turns light offshore from the east, and the waves clean right up. Swell is 4ft from the NW, period 10 seconds, energy 292 (moderate). The water is running 76°F, which is a whopping 7°F warmer than average for this time of year—very unusual. This is your best window. Mundaka is a famous river mouth wave, and with that offshore breeze, it’ll be reeling. But expect a crowd—it’s “often” busy.
Wednesday the 29th morning goes glassy, but the swell is only 3ft NW, period 9 seconds, and energy is low (143). Surfable, but nothing to write home about.
From Thursday the 30th through to Sunday the 9th of August, it’s dead. Swell drops to 1ft to 3ft, wind is mostly cross-onshore or onshore, and the energy is weak (under 100). There are a couple of glassy mornings on the 3rd and 8th of August, but with negligible swell, it’s a flat spell. The 5th of August sees a tiny bump to 4ft, but the wind is cross-shore and choppy. Not worth it.
So, the standout is Tuesday the 28th of July at dawn. Clean, offshore, warm water, and a solid groundswell. That’s your day.
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.
