The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin' for the next couple of weeks.
Right off the bat, I gotta be straight with you – the surf scene is pretty flat and quiet for a long stretch. We’re looking at a real dry spell from now until mid-month. Don’t get too excited by the early days because the waves are tiny and the conditions are just ordinary. For the first nine days, from Wednesday the 5th through to Sunday the 16th of August, it’s a whole lot of nothing special. You’ll see small, weak swells with poor surf quality, hardly worth paddling out for. The water temp is sitting at 70°, which is a touch warmer than normal for this time of year, so at least it’ll be a nice dip if you do go for a float.
Now, the one bright spot that’s worth marking on your calendar is Saturday the 15th of August. That morning at El Mongol (a reef break) we finally get a decent pulse of energy. The swell pushes up to 4ft from the NNW with a period of 10 seconds, so a solid groundswell with some shape. The combined energy is strong at 430 (moderate wave energy), and the wind is glassy, calm – a light air from the NNE. That’s gonna mean clean, lined-up waves. It’s a consistent spot, and it’s fairly exposed to the NW, so it’ll pick up that swell well. The crowd factor is listed as “often,” so expect a few locals out, but nothing too hectic. The water temp anomaly is missing for that day, but based on earlier readings, it’ll still be a touch warmer than average. This is the standout of the whole outlook – the only real window of quality surf.
After that, the energy drops off again. Sunday the 16th and Monday the 17th see a return to small, weak, and messy conditions. The 18th of August has a bit of size again, 3ft from the NW, but the wind turns onshore, so it’ll be bumpy. The 19th and 20th are mostly small and poor, with some rain showers around. So really, if you’re keen, you’ve got one morning – Saturday the 15th – to make it happen. The rest of the time, the ocean is just taking a nap.
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.
