The Lowdown
G’day, Rusty here. We’ve got a solid run of surf on the cards at Ekas-Outside over the next couple of weeks. This is a fairly consistent reef setup that’s fairly exposed, so when the SSW groundswells line up, it can really turn on. The water temp is about average for this time of year, nothing crazy. The first few days of the run-up are building, so don’t expect perfection straight away, but the quality sharpens up nicely mid-week.
Looking at Monday morning 17 August, we’re already into a clean 5ft SSW swell with a 14-second period – that’s proper groundswell energy. Combined energy is strong at 1098. Wind is cross-off from the ESE at 9 mph, so the surface is glassy and clean. It’s a nice intro, but the tide might be a factor in the arvo when it drops to marginal.
Tuesday 18 August morning is where it starts getting interesting. Clean 4ft SSW swell, but the period jumps to 16 seconds – that’s long-period groundswell, meaning shaped-up lines and decent gaps between sets. Combined energy is very strong at 2053. The wind is offshore from the E at 9 mph, glassy conditions. This is a standout session for experienced surfers. The afternoon gets a bit lumpier with cross-off wind and a bigger 6ft swell, but the quality drops.
Wednesday 19 August morning is the pick of the first week. We’re looking at 8ft SW swell with an 18-second period – that’s very long-period groundswell. Combined energy is powerful at 3608. Winds are light cross-off from the ESE at 9 mph, so the reef will be clean and lined up. This is expert territory at that size, especially with such long-period energy – it could be too straight for a beach break, but Ekas-Outside is a reef, so it should handle it beautifully. The bit is chasing that Wednesday morning session.
From Thursday 20 August through to the end of August, we stay in the 6ft to 10ft range, mostly SW to SSW groundswell, with periods between 13 and 18 seconds. Winds are cross-off from the SE and SSE, 12 to 16 mph, which keeps things clean but on the stronger side. Combined energy sits in the moderate to strong range (two to four thousand). Conditions are consistently clean but the tide/timing makes a few sessions marginal – still, plenty of fun to be had for the crew who know the reef.
One more standout to keep an eye on is Friday 28 August morning. Clean 7ft SSW swell with 14 seconds, from a gentle cross-off breeze. Combined energy is 1894. It looks like a crisp, powerful morning for experienced surfers. The following few days drop off a touch but stay in the 4ft to 6ft zone with long-period SW groundswell lingers, so it doesn’t fully die.
Crowds at Ekas-Outside can be a thing – it’s a well-known reef and when it’s good, you’ll have company. Get in early for the cleanest windows.
Alright, that’s the story from here. Get amongst it.

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.
