Alright folks, Rusty here. Let’s have a look at what’s coming down the line for this spot.
Honestly, the next week and a half is a bit of a write-off. We're looking at a long stretch of tiny, weak waves with poor surf conditions day after day. From Sunday the 12th right through to at least the morning of Monday the 20th, it’s a lot of flatness and frustration. The swell is small, mostly under 2 ft, and the energy is weak, barely hitting triple digits on the combined energy scale. There’s a couple of glassy mornings, like Monday the 13th and Tuesday the 14th, but even then the waves are just too small to bother with. It’s a real test of patience.
But then, things start to look promising. The first real standout arrives on the morning of Tuesday the 22nd of July at El Mongol (reef). The swell finally shows up, a clean 4 ft from the NNW with a period of 9 seconds, and the combined energy jumps to a solid 338 – moderate wave energy, but it’s a big step up. The wind is glassy, dead calm, so the face will be clean. The water temp is running about 68°F, which is a touch warmer than normal for this time of year, so you might not need a full suit. The morning of Wednesday the 22nd is the pick of the first half of the week.
Then, if you can hold out, the real daddy swell is on the horizon. The morning of Thursday the 23rd of July is the absolute standout of the entire 16-day window. We’re talking a solid 8 ft of groundswell from the NNW, with a period of 11 seconds and a massive combined energy of 1292. That’s strong wave energy. This is a reef break, so that long-period groundswell will set up nicely, giving you powerful, well-shaped lines. The wind is glassy again, which is a massive plus. Now, with size over 8 ft on the afternoon, it’s getting into expert-only territory, but the morning session at 8 ft is going to be pumping for anyone with the skills. Expect very good surf conditions. The morning of Friday the 24th also looks excellent, with 6 ft and glassy wind, a strong follow-up day.
So, the long story short: be patient through the first week. The only real green lights are the morning of Tuesday the 22nd, and especially the morning of Thursday the 23rd. That’s the one to circle on the calendar. Crowds at El Mongol are likely to be there often, so get there early for the best of it.
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.
