The Lowdown
Alright, this is Rusty, and I'm looking at the forecast for the next couple of weeks. Things start off a bit rough, but we've got a couple of proper windows to get excited about.
We’re looking at Playa de Gros. It’s a beginner-friendly spot that’s very consistent, and it’s exposed to the NW. The water temp is about average for this time of year, so nothing crazy there.
The first real opportunity comes on Monday the 14th of September. The morning session is looking glassy with a clean 4ft NW swell. The combined energy is at a moderate 416. That’s a solid, fun little wave for getting out there. The afternoon gets a bit crossed up with a light NNE breeze, so the morning is the call.
After that, we hit a dry spell. Tuesday through Friday is mostly poor with onshore winds and messy conditions. The swell is small and wind-affected, so don’t bother paddling out.
We get a proper pulse on Saturday the 19th. The morning is looking clean with a cross-offshore breeze and a solid 7ft NW swell. The combined energy jumps up to 1619, which is strong. This is a bigger day – it’s going to be too much for beginners, but for anyone with some experience, that’s a proper session. The swell period is 13 seconds, so it’s a groundswell with good shape, though at a beach break like this it might wall up a bit. Expect crowds here because it’s often busy, but for a Saturday morning with those conditions, it’s worth it.
Sunday the 20th is a reset. The morning is glassy again, with a 5ft NW swell and moderate energy at 504. That’s the best all-rounder of the run – clean, fun, and accessible for everyone. Monday the 21st brings another standout, but it's for the experienced crew. The morning is flat calm with a 7ft NW swell, period of 14 seconds, and combined energy of 1422. That’s powerful, clean, and lined up, but it’s going to be too big for the average surfer. Tuesday the 22nd is similar in the morning – glassy, 6ft, and strong at 1037 – another expert-only window.
After that, it fades. From Wednesday the 23rd onward, the swell drops off quickly. There’s a couple of small, clean days around the 26th and 27th with tiny 1ft to 1ft WNW swells, but the energy is weak. You might get a longboard out, but it’s pretty ordinary. The last week is a slow fade-out with very little to offer.
To sum it up: your best bets are the glassy mornings on the 14th and 20th for the everyday surfer. For the bigger, more powerful stuff, the 19th, 21st, and 22nd are the ones – but those are for experienced surfers only. Don't sleep on the 20th, that's the sweet spot.
Rusty.

Information about the Playa de Gros Surf forecast
The above surf forecast table for Playa de Gros provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Playa de Gros can be found by selecting the local surf guide option on the grey menu. Our Playa de Gros 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 (Playa de Gros) 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 Playa de Gros 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.
Playa de Gros is 4 km (2 miles) from San Sebastian. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in San Sebastian. San Sebastian has rooms for a wide range of budgets as well as car hire and transport links.
