The Lowdown
Alright, Rusty here. Let's take a look at what's on the cards for El Mongol.
Right off the bat, the first part of the week is a bit of a write-off. The surf is there, but it's just not happening. Monday the 20th through to Wednesday the 23rd see some waist-high, short-period windswell mixing in, but the conditions are just ordinary. The wind is a cross-offshore, which is fine, but the wave quality is poor and the energy is weak. Honestly, there's nothing to get excited about. We then hit a real flat spell from Thursday the 23rd right through to Monday the 27th of July. The swell drops away to almost nothing, with a mix of onshore and cross-onshore winds making a mess of things. It's a proper lull, and you'd be wasting your time paddling out.
Now, things start to look up on Tuesday the 28th of July. The swell fills in properly from the NNW, pushing 5ft, with a moderate energy reading (635). The wind is a light cross-offshore from the ENE, keeping the surface clean. This is the first real standout of the forecast. It's a solid, consistent reef break setup. The water is much warmer than normal for this time of year.
Wednesday the 29th of July looks even better. The morning session sees a similar 5ft swell from the NNW, but the energy jumps up to 651, and the light cross-offshore wind is still holding. This is the best on offer for the whole outlook. The waves will have a bit more push and shape. It's a consistent spot, so you can expect plenty of waves, but it does get crowded often, so be prepared for company.
The good vibes carry into the first week of August. Thursday the 30th of July is glassy in the morning with a 4ft swell from the NW, but the energy is lower. Then we have a run of mornings from Friday the 31st of July through to Tuesday the 4th of August where the swell is a bit smaller, around 4ft to 5ft, but the winds are light and clean, with Monday the 3rd and Tuesday the 4th of August mornings looking particularly promising with glassy or clean conditions. The energy on Tuesday the 4th of August morning jumps back up to 329, which is a solid sign.
To sum it up: the first week is a total dud until the 28th. The real highlights are the mornings of Tuesday the 28th and Wednesday the 29th of July. That's where you want to be. After that, it's a steady run of smaller but clean mornings, which is a decent trade-off.
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.
