The Lowdown
Alright, this is Rusty. Let’s break it down.
First off, we’ve got a long stretch of nothing much to write home about. From now until around August 22nd, the surf is mostly flat or just plain messy. Small, weak swell and bad wind. A real bummer.
The first real light at the end of the tunnel comes on the morning of Saturday the 22nd. That’s the one to circle. El Mongol is a reef break that’s fairly exposed, and on that morning we’re looking at a clean 4ft swell from the NNW. The wind is glassy, dead calm – that’s huge, it’s going to be smooth as glass. The combined energy is moderate at 375, with a period of 10 seconds, so there’s some real push. This is the best session on offer. Keep in mind, this spot can get crowded often, so plan to be early.
The afternoon of the 22nd sees the swell bump to about 5ft, but the wind turns onshore, so the quality drops fast. That morning window is the one.
Before that, on the morning of the 21st, there’s a tiny chance with a 3ft NNW swell and glassy wind, but the energy is much lower at 181 and conditions are only "very ordinary." Not a priority.
Everything else in this 16-day run is either too small, too onshore, or flat. Water temp is about average for this time of year, nothing unusual.
So, bottom line: the first week and a half is a write-off. The only real standout is the morning of Saturday the 22nd at El Mongol. That’s your best chance. After that, it fades again.
Rusty.

Information about the El Mongol Surf forecast
The above surf forecast table for El Mongol provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at El Mongol can be found by selecting the local surf guide option on the grey menu. Our El Mongol 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 (El Mongol) 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 El Mongol 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.
El Mongol is 2 km (1 miles) from Gijon. If you plan a holiday in Asturias, look for hotels and other accommodation in Gijon. Gijon has rooms for a wide range of budgets as well as car hire and transport links.
