The Lowdown
Alright folks, Rusty here with a look at what’s on offer at Zarautz over the next couple of weeks.
Right off the bat, the water is sitting at a warm 76°, which is about 5° warmer than usual for this time of year – that’s a notable difference, so you’ll be comfortable in a shorty or even a spring suit.
The first few days are pretty flat and uninspiring. From Saturday the 15th through to Wednesday the 19th, we’ve got small, weak swell with short periods – mostly under 3ft and periods around 5 to 8 seconds. The combined energy is weak, reading between 21 and 94, just not enough push for a proper wave. The wind is glassy in the mornings, which is a tease, but the swell just isn't there. Thursday the 20th sees a jump in period to 11 seconds, and the energy climbs into the moderate range (150-196), but the wind is onshore and messy, so it's a no-go.
The first real standout of the outlook lands on Friday the 21st of August. The morning session sees a 5ft swell from the NW with a long 11-second period, and the energy is strong at 515. The caveat here is the wind is cross-onshore, creating bumpy conditions. If you’re an expert looking for some raw power, it’ll be worth a look, but it’s not for beginners.
Things clean up nicely on Saturday the 22nd of August. We’ve got a 4ft NW swell, a solid 10-second period, and glassy conditions in the morning. The combined energy is a healthy 210, and this is the best bet for the first week. It’s a solid, surfable wave with clean faces.
The middle of the next week turns choppy again from Sunday the 23rd through Monday the 24th, with rain and onshore winds spoiling the shape.
Then we get another promising stretch. Tuesday the 25th of August morning is glassy with a 3ft NW swell, period at 10 seconds, and energy at 183. It’s surfable but ordinary. Wednesday the 26th of August morning is the pick of the second week: glassy winds, a 3ft NW swell, 9-second period, and energy jumping to 232. Good conditions expected.
Finally, Thursday the 27th of August morning offers another solid window. Glassy offshore wind from the SSW, a 4ft NW swell, and an 11-second period with energy at 326. That one has real potential for clean, well-shaped waves.
So to sum it up: the standout is Saturday the 22nd morning for clean, fun waves, with Thursday the 27th morning being a close second. The rest is a mixed bag of small surf or onshore chop. Keep an eye on those glassy windows – they’re the ones to wake up for.
Rusty.

Information about the Zarautz Surf forecast
The above surf forecast table for Zarautz provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Zarautz can be found by selecting the local surf guide option on the grey menu. Our Zarautz 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 (Zarautz) 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 Zarautz 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.
