The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Ekas-Outside. This is a reef setup, fairly exposed to the swell, and it’s a beginner-friendly wave which is a nice bonus. The water is sitting at 79.5°, which is pretty much what you’d expect for this time of year.
We’ve got a solid run of surf on the horizon, but it kicks off with a bit of a mixed bag. Wednesday the 12th sees swell around 5.6 ft to 6.6 ft from the SSW, with a period of 14 to 16 seconds, giving it some real groundswell grunt. The combined energy is strong (2225), but the wind is a cross-off from the SE at 16 mph, which keeps things clean but not absolutely glassy. It’s rideable, but the conditions are a bit marginal.
Thursday the 13th picks up a notch. Swell hits 7.5 ft to 8.2 ft from the SSW, period pushing 16 to 17 seconds, and the energy jumps a lot (2840 to 3554). Still cross-off winds, but it’s clean. The size is getting into the zone where beginners might want to pick their moments carefully though.
Friday the 14th holds steady with 6.6 ft to 7.2 ft SSW swell, and the energy is still decent (1946 to 2669). The weekend (Saturday 15th and Sunday 16th) keeps that same vibe: 6.9 ft to 7.5 ft from the SSW, clean but cross-off. Consistency is fair, but nothing is absolutely screaming “standout” yet.
Now, Monday the 17th is a real shift. The swell drops a bit to 4.9 ft to 5.2 ft, but the period is 14 seconds and the wind eases to a light breeze at 6 mph in the morning. That’s the cleanest we’ve seen. The combined energy is moderate (1094), but the conditions are looking very good for a relaxed session.
The standout period, though, starts Tuesday the 18th. Swell goes 4.6 ft to 5.9 ft, but the direction shifts to SW, period jumps to 16 seconds, and the energy spikes (2368 to 2669). The wind is still a cross-off but it’s a gentle breeze, and the reports say “excellent surf conditions for experienced surfers.” That’s a big tick for quality.
Wednesday the 19th and Thursday the 20th see the swell really fire up. Swell heights of 7.9 ft to 9.8 ft, period 16 to 18 seconds, and the energy is massive (3415 to 4506). This is powerful, long-period groundswell. At 9.8 ft, this is expert territory. The break is a reef, so it’ll handle the size well, but the wind stays cross-off, not offshore. It’s still clean, but not perfection.
Friday the 21st drops back a bit, but then Saturday the 22nd and Sunday the 23rd have another pulse of 9.8 ft swell, keeping the energy high (3957 to 3905). Monday the 24th is another 9.8 ft day with massive energy (4290).
Looking further out, the second week sees a bit of a drop-off. From Tuesday the 25th to Thursday the 27th, the swell eases to 3.6 ft to 5.9 ft, but the period stays long at 14 to 20 seconds. The energy is moderate (1496 to 1800). The wind remains cross-off and clean. It’s still surfable, but nothing like the punch of that week from the 18th to the 24th.
Overall, the best on offer is the window from Tuesday the 18th through to Monday the 24th. The swell is solid, the energy is high, and it stays clean. If you can only pick one session, aim for the morning of Tuesday the 18th when the conditions are described as excellent for experienced surfers, with a gentle breeze and that long, powerful SW groundswell. That’s your standout.
Stay safe, check the tides, and enjoy the ride.

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.
