The Lowdown
Right, you’ll have to wait a bit this week because the ocean is just washing in with weak, onshore slop. Tuesday is a write-off – poor conditions with a choppy cross-onshore. It’s not until Thursday morning the 17th that we see some life, but even then it’s only marginal. Friday morning the 18th looks like the first real chance to get wet.
Friday morning the 18th brings clean, cross-offshore conditions with a 3ft NW swell at 9 seconds from the NNW. Wave energy is moderate here (272). The water at Zarautz is sitting at 73°F right now, which is 5°F warmer than normal for this time of year – that's notably warm, so you're in for a pleasant session. It's a beginner-friendly break, very consistent, and the crowds can be often here. This morning is a decent option to stretch the arms.
The standout of the whole forecast is Saturday morning the 19th. You’ve got a clean 8ft NW groundswell, period a solid 13 seconds, with glassy conditions and a light SE breeze. The combined energy is strong (1756). This is excellent surf for experienced surfers – the size is just under 8ft, so it’s getting up there, but it's not too big for a capable surfer. The long period will make the waves hold shape well on this exposed beach, though expect longer lulls between sets. Crowds will likely be an issue as this is the clear highlight.
Sunday the 20th drops back a bit. The morning sees 5ft NW at 11 seconds with a cross-on light breeze. It's clean enough for a fun session for mixed ability. From Monday the 21st into the following week, the swell drops and we get a series of smaller, glassy mornings – good for beginners and longboarders. The morning of Monday the 21st has a glassy 4ft NW swell, and Tuesday morning the 22nd is glassy with 4ft NW. Nothing special, but clean.
Wednesday morning the 23rd is a little gem – a glassy 3ft WNW swell but with a very long 15-second period (512 energy). That’s a proper long-period groundswell, so at a beach break it might be a bit straight, but the conditions are glassy.
The last week is dominated by small NW and WNW swells, mostly in the 3-4ft range, with calm to light winds. The morning of Monday the 28th and Tuesday the 29th both have glassy conditions but only 3-3ft of swell. It's a consistent run of clean small surf for the confident beginner.
Don't get excited about the very end of the month. Saturday the 26th and Sunday the 27th are both marginal and onshore. That 20-second period on Saturday morning (3ft WNW) is a tease – it'll be too weak and straight to do much on the beach.
So, if you're looking for one day: Saturday morning the 19th is the one. Get out early for the glass, good energy, and a proper NW groundswell.

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.
