The Lowdown
Alright, let’s talk Zarautz. The first few days are a bit of a washout, nothing doing. Real small stuff, weak energy, just not worth paddling out for.
The first real chance comes Thursday morning, August 20th. Swell pushes to 4ft from the NW, with a 11-second period, so it’s got some groundswell grunt. The combined energy is 304 (moderate), and the wind is dead calm, glassy. That’s a clean, inviting window. Water temp is 77°, which is much warmer than average for the time of year, about 5° above normal. That’s a real bonus.
Friday morning, August 21st, brings a bit more size at 5ft from the NW, 10-second period, and energy of 478 (moderate). Light offshore glassy wind again. A solid morning, but the afternoon gets a bit choppy.
The real standout is shaping up for the start of September. Tuesday, September 1st, the afternoon rolls in with 6ft from the NW, 11 seconds, and strong energy of 671. The wind is light offshore, clean. That’s a serious session. Wednesday morning, September 2nd, keeps the wave alive with 5ft from the NW, 11 seconds, and 662 (strong) energy, with offshore winds. The afternoon on Wednesday gets a bit blown out, but the morning is your target.
Zarautz is a very consistent beach break, good for beginners. The 4ft to 5ft range is perfect for most. That 6ft to 6ft stuff is getting into solid intermediate territory, still fun. The 11-second period gives it proper shape, but on a beach, it can close out a bit, so watch the banks.
The top pick is Tuesday, September 1st afternoon and Wednesday, September 2nd morning. That’s the one. The Thursday, Friday, and Saturday sessions before are your warm-ups.

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.
