The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at El Mongol for the next couple of weeks.
Honestly, the first week is a slow grind. We’ve got a long stretch of nothing special from Tuesday, 4 August right through to the middle of the following week. The water is sitting at 70° and feels a touch warmer than normal for this time of year, but that’s about the only highlight early on. There’s a gap of several days here with no real surf to get excited about.
Thursday morning, 6 August, shows a small pulse of 4 ft from the NNW with a short period of 8 seconds. The combined energy is moderate (191), and the wind is cross-off from the ENE, keeping things clean. It’s surfable, but very ordinary. That’s the best we’ve got for the first week, and it’s not saying much.
Now, Tuesday morning, 11 August, is where things start to lift. Swell is 4 ft from the NNW, period stretches to 10 seconds, and the energy is solid (280). With a glassy cross-off flow from the ENE, conditions are clean. This is a good session, but it’s not the standout.
The real standout, and the one I’d circle on the calendar, is Wednesday morning, 19 August. This is the one to wait for. We’ve got a solid 10 ft groundswell from the NW, with a 10-second period, and a massive combined energy reading of 2182. That’s strong wave energy. The wind is glassy from the NE. For experienced surfers, this is a gem. It’s a reef break and it’s consistent, so expect proper shaped waves. The swell direction (NW) lines up nicely with the optimum for this spot (NNW). On the downside, at 10 ft, this is expert territory only. Also, crowds are often a factor here, so you’ll have company.
Wednesday afternoon, 19 August, holds similar size at 10 ft, but the wind goes cross-shore from the NE, which adds a little chop. Still a solid option for the experienced crew.
There’s a smaller window on Saturday morning, 15 August, with 4 ft from the NNW, 10-second period, and glassy conditions, giving a combined energy of 294. That’s a decent morning wave with clean conditions, but it’s not the standout.
Overall, the first week is a write-off unless you’re desperate. The second week builds nicely, and that 19 August window is the one to aim for. Don’t get your hopes up for the early days, but the long-range looks promising.
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.
