The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead at El Mongol, and while it’s not all firing, there are some absolute gems in there.

The action starts right away. Monday morning is a beauty – crystal clear, glassy as a mirror, and a clean 3-foot NW swell with a long 13-second period. The water temp is about average for this time of year. It’s gentle, clean, and the sort of session you’ll be smiling about all day. The combined energy is moderate at 345, so you’ll feel some push. This is a perfect warm-up.

Things get a little more interesting come Wednesday morning, the 9th. The swell jumps to 5 feet from the NNW, still glassy with zero wind. The energy is climbing to 489, and it’s a solid intermediate-friendly wave. The period has dropped to 8 seconds, so it’s a bit more local, but the clean conditions more than make up for it.

Thursday morning, the 10th, is similar: 4.6-foot NNW swell, glassy, and clean energy (397). A very consistent, high-quality option.

But the real standout, the one you circle on the calendar, is Sunday, the 13th. That morning is calling for a fun 5.6-foot groundswell from the NNW, with a super long 14-second period. The energy is a massive 1227 – that’s serious grunt. The wind is just a slight air from the east, keeping it clean. This is a reef break, and that long-period swell is going to march in with proper lines, wrapping around the reef. It’s set up for the best waves of the whole period. It’s not for beginners at that size, but for the rest of us, this is the one.

We do have a bit of a lull after the 13th. The 14th and 15th are still surfable but a bit more ordinary, with cross/onshore winds making things messier. Then the 16th morning picks up again with a clean 5.2-foot NW swell (603 energy) and offshore winds.

Another big day to watch is Thursday, the 17th. That morning shows a clean 6.6-foot NNW swell (888 energy), and the afternoon hits 6.6 feet with 1027 energy. That’s getting into expert-only territory, but for the crew who can handle it, it’s going to be a powerful, clean session.

The 18th, 20th, and 22nd all have glassy mornings with solid, surfable waves in the 3.3 to 5.2-foot range, rounding out the window nicely.

So, the best on offer? Hands down, Sunday, the 13th, for the combination of size, period, and glassy conditions. That’s the session to chase. The 17th is a close second for power and size, but it’s for the experienced crew only.

Stay stoked and get after it.

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.
