The Lowdown
Hey, Rusty here. One break in the mix for the next couple weeks – El Mongol – and it’s got some character. Water’s about 69°F, which is right where it should be for this time of year, nothing weird.
Sunday the 30th starts off flat and messy. There’s a 5ft NW swell, but rain and onshore wind kill it. Energy’s weak to moderate (446 to 460). Not worth getting wet.
Monday 31st August is the pick. The morning is glassy, dead calm, with a clean 6ft NW swell, period 10 seconds, and energy at 738 (strong). El Mongol’s a reef break that works on NW swell from the NNW direction – this is prime. The afternoon holds 6ft but gets side-on breeze, so hit the morning.
Tuesday 1st September keeps it fun – glassy morning with 5ft and 400 energy, then a clean afternoon with cross-off wind.
Then it dies. From Wednesday 2nd through Thursday 10th, waves drop under 3ft, energy falls into double digits, and it’s mostly poor or just ordinary. Thursday 3rd is especially weak.
Friday 4th September morning shows a 5ft NW groundswell with a 13-second period and glassy wind, but it’s only 734 energy – a tease. That long period might make it break a bit straight on the reef.
Saturday 5th September morning is the big one – 7ft NNW swell, 13-second period, clean cross-off wind, and energy screaming at 1585 (very strong). This is sick, but over 8ft – experts only. Afternoon drops to 6ft but wind picks up.
Sunday 6th morning is a glassy 4ft session with 461 energy – a nice easy day. After that, from Monday 7th onward, it’s all small and ordinary through Monday 14th. The last days are weak and messy.
Two real standouts: Monday 31st August morning for clean, glassy 6ft, and Saturday 5th September morning for the big 7ft groundswell – that one’s for the experienced crew. The rest is a long stretch of small surf and poor conditions.
Stay tuned, the forecasts can shift.
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.
