The Lowdown
Alright folks, Rusty here. Let’s get into it for this little patch of coast. We’ve got a 16-day window, but you’ll be waiting a bit before anything really gets going.
The first proper surf recommendation doesn’t kick in until Thursday morning, the 13th of August. Before that, it’s basically flat and sad. The early part of the week is a write-off, so don’t bother paddling out until then.
The standout call here is El Mongol (a reef setup). This spot is a consistent performer, so it’s not a rare thing to see it working. For the best of the best, you’re looking at Friday morning, the 21st of August. That’s when we get a solid 4ft swell from the NNW, with a nice long 11-second period pushing in. The energy is strong (500 in the combined energy rating), and the wind is glassy – a total game-changer. This will be clean, punchy, and well worth the wait. The swell direction is pretty much bang on the optimum for this break, so expect it to line up beautifully. It’s got enough size to be fun for intermediates, but not too big to be a problem.
Thursday morning, the 20th of August, is worth a mention. It’s a bit of a gamble with a 3ft swell from the NW and a 10-second period, but the energy is moderate (257). The wind is glassy, but the forecast says "poor surf conditions," so temper your expectations. It might be a sneaky session if you’re desperate.
After that, the 22nd and 23rd have some knee-to-waist high stuff (around 3ft to 3ft) with clean conditions, but nothing to write home about. The later part of the window, from the 24th onward, gets messy with strong onshore winds and rain, so the window slams shut.
The water temperature is about average for the time of year, so no weird surprises there.
Keep your eyes on that Friday the 21st morning session. That’s the one. Everything else is just filler.
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.
