The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for El Mongol.
First thing, the water is sitting at 71°, which is a touch warmer than normal for this time of year. Nothing crazy, but it’s a nice little bonus.
The next few days are a write-off, honestly. Wednesday and Thursday are poor, with tiny, weak swell and messy conditions. The combined energy is barely reaching 99 (weak), and the swell is short-period, so don’t bother paddling out.
We finally get a glimmer of life on Friday morning, the 28th of August. A 4ft NW groundswell (10 seconds) rolls in, with a light SSW cross-offshore breeze. The energy jumps to 262 (moderate), and it’s clean. It’s only surfable, not pumping, but it’s the first real chance. The afternoon turns into a mess though, with a 8ft cross-on howler from the W that’s blown out and choppy.
Saturday the 29th has a clean, glassy start with a 4ft NW swell, but it’s ordinary. The energy is moderate (213). Sunday morning the 30th is the first standout. We’ve got a 6ft NW swell with a 10-second period, dead calm WNW wind – glassy perfection. The combined energy is 707 (strong), and the forecast says “very good surf conditions.” This is the one to circle. The afternoon turns a bit bumpy with cross-onshore wind, so hit it early.
Monday the 31st is still solid, with 6ft NW swell and glassy conditions in the morning. Energy is strong (630). Good, but not quite as clean as Sunday.
Tuesday the 1st of September drops off a bit, but the morning is glassy with a 4ft NW swell. Clean, but only moderate energy (297). The rest of the first week into early September is a slow fade of small, weak swell and poor conditions.
Now, looking ahead to the 5th of September (Saturday), we get a nice pulse. A 5ft NW groundswell with a 12-second period, glassy conditions in the morning. Energy is strong (586). This is a solid option, but remember, it’s a week away, so keep an eye on the forecast.
The 6th of September (Sunday) brings a very long-period NNW groundswell of 15 seconds. The morning is tiny at 2ft, but glassy. The afternoon, however, sees the swell jump to 6ft with a 14-second period, and the energy rockets to 1337 (very strong). This is a big, powerful swell. The wind is a light cross-shore, so it’s not perfect, but the potential is huge. That long period will make it break straight at the beach, but El Mongol is a reef, so it could handle it beautifully. This is a standout for the experts.
Finally, the 7th of September (Monday) is another standout. A 6ft NNW groundswell (12 seconds) with a light NE breeze making it glassy in the morning. Energy is 835 (strong). The forecast says “very good surf conditions.” This is the second best on offer in the whole window.
The week after that fades out again with small, weak swell and poor conditions.
So, the best bets are Sunday the 30th of August for the cleanest, most user-friendly conditions, and Monday the 7th of September for the serious power. The 6th of September is for the experienced crew only.
Rusty out.

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.
