The Lowdown
Alright folks, Rusty here with the surf. We've got some proper northwest groundswell on the way, and it's looking firing for a few days.
The call is for El Mongol. It's a reef setup, so it holds that size well. The first real push comes in on Friday the 18th. We’re talking a solid 2.1m of swell with a long 13-second period, which is going to light it up. The water is a warm 21° which is a touch warmer than usual, so that's a bonus.
Friday morning is the absolute standout. It's clean, glassy, and the energy is pumping. This is for the experienced crew. The afternoon jumps up to 3.0m, but it gets cross-shore and messy, so only the experts will get anything out of that. Saturday the 19th keeps the size up around 2.2m with clean offshore winds, and that's another cracker of a day.
The swell stays rideable through Sunday and Monday, with clean conditions and waves in the 1.5m to 1.7m range. It's looking consistent.
There's a bit of a lull in the mix around Thursday the 24th and into the weekend, with smaller, weaker surf. It’s not flat, but nothing to get excited about.
Then, looking further ahead, there's a pulse of long-period groundswell for Monday the 28th. It's a way off, so don't book your flights yet, but it's showing good potential with clean conditions. The water will be warm, and the vibes will be high.
Keep it on your radar. More on this later in the week.
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.
