Zarautz Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break down the next couple of weeks at Zarautz. We’ve got a bit of a slow start, but some real gems are coming up, especially this weekend. The water is sitting at a very warm 75°F, which is a solid 5°F above the norm for this time of year—so expect that tropical bathwater feel.

The first real action kicks off on Friday morning, the 28th of August. It’s not the biggest swell, but with a clean 4ft from the WNW and a light cross-offshore breeze, it’s setting up nicely. The wave energy is moderate (205), and the period is a short 7 seconds, so it’ll be a bit choppy in the lineup, but still fun for a beginner-friendly wave like this.

Then we hit the standout of the whole stretch: Saturday, the 29th of August. The morning is magic—absolutely glassy, zero wind, and a solid 6ft of WNW swell. The wave energy jumps to a strong 497, and the period extends to 9 seconds. This is the best on offer. Clean, fun, and consistent. The afternoon stays glassy with a 5ft swell, so you can surf all day without a worry.

Sunday morning, the 30th, still has fun 5ft waves, but a light cross-onshore breeze puts a few ripples on the face. The energy is still solid at 471. It’s surfable, but Saturday is the clear winner.

Monday morning, the 31st, brings back the glassy conditions with 5ft WNW swell (energy 300). A great option if you missed the weekend. The afternoons through the next few days get a bit messy with onshore winds, so plan for mornings.

We hit a dry spell from Tuesday, the 1st of September, through to Thursday, the 3rd. The swell drops off hard, and the conditions are mostly poor or marginal. Thursday morning has a glassy 2ft, but it’s barely a ripple.

The surf picks up again on Saturday, the 5th of September. The morning has 3ft from the NW with a longer 11-second period (energy 214), but a light cross-onshore wind. The afternoon gets more interesting—4ft and a very long 13-second period (energy 466), but it’s onshore. This is a groundswell with a long period, so it’ll be better at points or reefs than a beach break like Zarautz. Keep that in mind.

Monday, the 7th of September, is a morning call. Glassy conditions, 4ft NW swell, 10-second period, and energy of 316. Clean and fun.

The last few days fade out. Wednesday, the 9th, has a glassy 3ft with a long 10-second period (energy 200) in the afternoon—clean but small. By Friday, the 11th, it’s back to ankle-biters.

So here’s the takeaway: Saturday, the 29th of August (morning) is your absolute best bet. Clean, glassy, with 6ft of WNW swell. If you can’t make that, Monday morning, the 31st, and Monday, the 7th of September (morning) are your next best windows. The long-period swell on the 5th is worth a look if you’re a more experienced surfer at a point break.

Rusty out.
