The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf on the horizon at one spot that’s looking pretty consistent, but you’ll need to pick your moments.
The overall pattern is a long, drawn-out pulse of groundswell from the south-southwest to southwest. It’s not going to be pumping every session, but the energy is there day after day. The water’s sitting at 79°, which is about average for this time of year, so no surprises there.
Kicking off on Thursday the 10th, we’ve got a clean 6ft swell from the SSW with a very long 15-second period. The combined swell energy is strong at 2142, but it’s a bit raw. The wind is a cross-off from the southeast at 16 mph, so it’ll be clean but with some texture. This one’s more for the experienced crew—at 6ft with that long period, it’ll be powerful, but the break is fairly consistent and exposed, so it should hold. By the afternoon, it bumps up to 7ft from the same direction with a 16-second period, and the energy jumps to 2376. That’s getting solid, but the tide conditions are questionable, so don’t expect perfection.
Friday the 11th sees a slight shift to a SW direction, still with a 16-second period. Morning waves are 6ft with energy at 1931, and the wind stays cross-off at 12 mph. It’s clean, but again, marginal tide conditions are the catch. The afternoon drops a bit in quality with stronger wind at 16 mph.
Saturday the 12th eases off a touch—5ft in the morning from the SW, period down to 14 seconds, energy at 1827. The wind is lighter, a gentle breeze at 9 mph, so it’ll be glassy and clean. This is a decent window for someone who wants a less intimidating wave. Afternoon picks up wind again to 16 mph, but the swell drops to 5ft.
Sunday the 13th is a standout morning. Swell from the SW at 6ft, but the period jumps to 18 seconds—that’s very long period groundswell. The energy is pumping at 2701. This kind of period loves a reef setup, and Ekas-Outside (Lombok) is exactly that. The wind is a cross-off at 16 mph, so it’ll be clean and powerful. The afternoon builds to 7ft with a 17-second period, energy at 2823. This is big, heavy, and only for experts. The sets will be long and clean, but if you’re not confident, stay on the beach.
Monday the 14th through Wednesday the 16th keeps the SW groundswell ticking over between 6ft and 6ft, with periods around 15-16 seconds. Wind stays cross-off from the SE at 12-16 mph. It’s consistent, clean, but the tide conditions keep it from being epic. Crowds are listed as "sometimes" here, so you might get some company, but it’s not a zoo.
Now, the real standout I’m looking at is Friday the 18th. The morning session has 6ft from the SW, 16-second period, energy at 1613, and the wind drops to a gentle breeze at 9 mph. The forecast notes say excellent surf conditions for experienced surfers. That’s the call. It’ll be clean, powerful, and the crowd profile is manageable. If you’re an experienced surfer, that’s your morning.
Saturday the 19th is smaller at 5ft, but still clean with light winds. Then Sunday the 20th brings a serious pulse—10ft from the SW with a 16-second period, energy hitting 4313 in the morning and 4056 in the afternoon. That’s very strong wave energy. This is big, heavy, and only for experts. The wind is cross-off at 12 mph, so it’ll be clean but treacherous. If you’re not a seasoned charger, give it a wide berth.
The following week eases off. Monday the 21st has 7ft, dropping to 4-6ft through the rest of the week. The period stays long, mostly 14-16 seconds. On Friday the 25th, we see a very long period of 21 seconds with a 4ft swell, energy at 2244. That’s a weird combo—small but incredibly long period. It’ll be clean, but the sets will be very spaced out and the wave shape might be too straight for the beach. Still, the reef at Ekas-Outside could turn that into a dreamy, glassy line.
So, if you’re after the best on offer, I’m calling Sunday the 13th morning for size and power, and Friday the 18th morning for the best combination of clean conditions, solid swell, and expert-friendly waves. The long-range stuff like the 25th is promising but less certain.
No big gaps in the surf here—this spot is churning out waves almost every day of the forecast. But remember, anything over 8ft is expert territory. Stay safe out there.
Rusty.

Information about the Ekas-Outside Surf forecast
The above surf forecast table for Ekas-Outside provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ekas-Outside can be found by selecting the local surf guide option on the grey menu. Our Ekas-Outside 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 (Ekas-Outside) 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 Ekas-Outside 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.
Ekas-Outside is 29 km (18 miles) from the city of Praya. If you plan a holiday in South Coast of Lombok, look for hotels and other accommodation in Praya. Praya has rooms for a wide range of budgets as well as car hire and transport links.
