The Lowdown
Alright folks, Rusty here. Let’s chat about what’s coming down the line at El Mongol.
First off, the next week is a bit of a bummer. We’re looking at a long flat spell to kick things off. Thursday morning the 13th might show some tiny 2ft waves, but that’s about it. From the 13th all the way through the 21st, it’s mostly weak, short-period slop. Plenty of glassy mornings, but the swell just doesn’t have any push. The combined energy is mostly under 200 (131), and some days it drops into the double digits (45). It’s pretty grim.
The big moment comes on Saturday morning, August 22nd. That’s the one. We’ve got clean 4ft waves from the NNW with a 9-second period, and the combined energy hits a solid 306 (moderate). The wind is dead glassy – perfect conditions for a reef break. That morning is your best chance all forecast. The water temp is about normal for this time of year, so nothing wild there.
But don’t sleep on it too long – that Saturday afternoon the wind gets messy and the quality tanks. After that, it’s back to small stuff. Monday the 24th has some clean offshore wind and 3ft surf (energy 127), but it’s not in the same league as Saturday morning.
Into the second week, it’s more of a struggle. The 25th is blown out with 25 km/h cross-onshore wind, and the 26th brings tiny 2ft waves with no power. There’s a little hope on the 28th (Friday morning) with 4ft from the north and clean cross-offshore wind, but the period is only 6 seconds and the energy is just 116. It’s rideable, but not a standout.
El Mongol is a reliable reef, but this stretch is mostly about waiting for that Saturday morning window. That’s the one to get on. The rest is low-energy, short-period, and tricky winds. The bright side? This spot can fire up quick when the swell shifts, so keep an eye on it.
Stay patient, 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.
