The Lowdown
Alright, Rusty again, same spot, different numbers. The first few days – Saturday the 18th and Sunday the 19th – are flat, with 0.7ft of nothing. Monday the 20th we get a 5ft pulse but it’s short-period and ordinary, with cross-off wind. Tuesday the 21st pushes to 7ft in the afternoon but still sloppy. Wednesday through Friday the 22nd to the 24th are poor again. The weekend of the 25th and 26th is tiny windswell with onshore wind.
Then Monday the 27th of July morning: 6ft from the NW, 9-second period, glassy, energy 546 – a clean session. The real standout is Wednesday the 29th of July morning: 6ft from the NNW, 11-second groundswell, cross-off breeze from the ENE at 6 mph, and a combined energy of 1162. That’s powerful, lined-up surf. The reef loves that direction and period. Crowds are often thick, so plan ahead. After that, Thursday the 30th and Friday the 31st have waist-high leftovers, and by August 1st it’s small again.
Bottom line: Wednesday the 29th morning is the one to chase, with Monday the 27th morning as a solid backup.

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.
