The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Ekas-Outside. The water temp is sitting at 80°, which is spot on for this time of year – no surprises there.
The pattern over the next couple of weeks is a long, drawn-out run of clean but marginal surf. The swell’s coming from the SSW and SW, and while there’s plenty of energy in the water – we’re looking at combined energy readings upwards of 2000 to over 4000 (moderate to strong) – the wave quality is being held back, likely by tide or some other factor. The wind stays cross-off from the SE through the whole run, which keeps the surface clean, so that’s a plus.
Right now, from Saturday 15th through to Monday 17th, we’ve got 7ft to 5ft of SSW swell, period around 14 to 17 seconds. That’s groundswell, and it’s got some punch, but the commentary says it’s marginal. The energy is moderate to strong (2790 down to 890), but the surf just isn’t firing on all cylinders. Tuesday 18th sees a bit of a drop, then a pulse of SW groundswell kicks in Wednesday 19th and Thursday 20th – the biggest of the whole run. Thursday morning peaks at 10ft (combined energy 4203 – strong), but at that size, it’s experts only. Still, that cross-off wind is a dream, so it’ll be clean.
The standout in the whole window for me is Sunday 30th August in the morning. We’ve got 7ft of SW groundswell with a 17-second period, light cross-off from the SSE at 9 mph, and the combined energy is a solid 2798 (strong). The forecast even calls it “excellent surf conditions for experienced surfers.” That’s the one to circle. The swell direction is straight into the optimum SSW direction for Ekas-Outside, a reef, and with that long period, the waves will have real shape and power. The crowd situation is “sometimes,” so you might have to share, but it won’t be chaos.
Before that, from around 21st August through to 28th August, the swell hangs around 3ft to 7ft, with periods dropping to 13-19 seconds. The energy is mostly moderate (541 to 2320), but the commentary keeps saying “marginal.” Not a lot of standouts in that stretch. The wind stays clean, though, so it’s not a complete write-off – just nothing to get excited about.
So, to wrap it up: the best bet is the morning of Sunday 30th August. If you can wait, that’s the session. The rest of the run is clean but average, with a few bigger days that are purely for the experienced crew.
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.
