The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the menu for Zarautz over the next couple of weeks.
It’s a slow cook to start, with the first few days serving up small, choppy waves and cross-onshore winds making a mess of things. From Friday 23rd through Monday 26th, you’re looking at a real dry spell – knee-high dribble and poor conditions. Don’t sweat it, because the end of the month brings the juice.
The standout window kicks off on Friday morning, 28th August. We’ve got a solid 8ft swell from the WNW with a 9-second period. The combined energy is pumping at 1080 – that’s strong, proper wave energy. The magic here is the glassy conditions: a slight air from the SSW and no wind. It’ll be clean, lined up, and punchy. This is for experienced surfers only at that size; beginners should stay on the sand.
Saturday morning, 29th August, is another gem. Swell drops back to a more friendly 6ft from the NW, 10-second period, and 531 energy. Glassy again with a light SE breeze. Clean, fun waves that are a bit more manageable. Not as powerful as Friday, but a solid morning session.
Sunday morning, 30th August, keeps the good times rolling – 5ft from the NW, glassy with calm winds. Energy is down to 328, but the quality is there for a relaxed, clean surf. Autumn is shaping up.
Looking ahead, Thursday morning, 3rd September, shows promise with a 6ft NW groundswell (11-second period) and 996 energy. Light cross-off winds from the WSW will keep it clean. Larger swell pushes in for the afternoon, but the wind swings NW and picks up, so the morning is the call.
Then on Saturday morning, 5th September, another solid pulse – 7ft from the WNW, 9-second period, 856 energy, and glassy conditions with a light northerly breeze. That’s a proper weekend session, but again, expert territory at that size.
The water is sitting at 76°F, with a 5°F anomaly, so it’s much warmer than typical for this time of year. Nice bonus for skinning it.
Crowds are a factor here – Zarautz is a very consistent spot, and it draws a crew, especially on the good days and weekends. Friday 28th morning will be busy, but the early glass-off might thin the herd.
The one to circle is Friday 28th morning – that’s the standout. Saturday 29th and Sunday 30th mornings are excellent backups. The 3rd and 5th September mornings are worth a look, but keep an eye on the wind as the date gets closer.
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.
