The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for El Mongol.
Right off the bat, the next few days are pretty ordinary. We’ve got some small, weak swell in the water, but the wind is all wrong—cross-off at best, but the swell is short-period and messy. The water is a balmy 71°, which is a massive 5° warmer than usual for this time of year, so it’s a real treat to be in the water, but the waves are just not there for a proper session.
The first real chance of anything decent comes on the morning of Monday, July 27th. A clean 5ft swell from the NNW rolls in, with a light cross-offshore breeze from the ENE. The energy jumps up to a moderate 536, and the period is a solid 10 seconds. This is a proper groundswell, and it’ll be breaking nicely on the reef. It’s still a manageable size for intermediates, but the conditions will be clean. The afternoon looks a bit messier, so the morning is your window.
After that, it fades right back off. The rest of the week is a write-off with small, weak, onshore junk. The only other sniff of something decent is the morning of Sunday, August 2nd. We get a glassy 4ft swell from the NW, with a moderate energy of 231. It’s a small, clean window, but it’s a week and a half away, so don’t bank on it just yet.
The standout here is clearly the Monday, July 27th morning session. The swell is solid, the wind is perfect, and the energy is there. The rest of the 16-day window is mostly flat or poor. It’s a long gap, so if you’ve got a flexible schedule, that Monday morning is your only real shot.
Alright, that’s the story. Stay salty.
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.
