The Lowdown
Alright folks, Rusty here. We’ve got a long look ahead at Ekas-Outside, and it’s a bit of a mixed bag. The water’s sitting at a warm 79°F, which is about average for this time of year, so no surprises there.
The pattern for the next couple of weeks is a steady run of SSW to SW swell, but with a constant cross-off wind from the SSE or SE. It’s clean, but it’s not gonna be perfect. The energy is moderate to strong throughout, with combined energy values mostly in the 1000s and 2000s, which means there’s plenty of push, but the wind and tide conditions are often flagged as questionable.
Let’s start with the here and now. From Monday, September 7th, through to Wednesday, September 16th, we’ve got a solid block of 5ft to 8ft SSW swell. The period is hanging in the 13 to 18 second range, so it’s proper groundswell. That’s good for shape and power, but at a reef break like Ekas-Outside, that long period will really focus the energy. The winds are a consistent cross-off, which will keep the faces clean, but it’s not a true offshore. The real killer here is that the overall forecast is saying “marginal” conditions for most of these days. The scores are low, so don’t expect classic perfection. The 8ft days on the 9th and 19th-20th are pushing into the “too big for beginners” zone, and the 10ft day on the 20th is only for the experienced crew.
The real standout, the one that makes you sit up and take notice, lands on Tuesday, September 22nd. That morning we’re looking at a 10ft swell from the SSW with a 20-second period – that’s a very long period groundswell. The combined energy jumps to 8955, which is strong. The afternoon gets even better: 12ft from the same direction with a 19-second period and energy hitting 10169, which is very strong. The wind is still a cross-off from the SSE at 20 km/h, but the raw power on offer is immense. This is a big, powerful reef swell. It’s a long way out, so it’s a promising one, not a guarantee, but it’s the only session that cracked a score of 7 out of 10. The 12ft waves are definitely for experts only.
The next best is the morning of Friday, September 18th. The swell drops to 4ft from the SW, but the period is a solid 17 seconds and the wind is only a gentle breeze from the SE. The commentary for that morning actually says “excellent surf conditions for experienced surfers.” It’s not the biggest, but the quality looks better than the rest of the run. That’s a sneaky good session.
The rest of the window is consistent but not firing. You’ll get waves every day, but the tide and wind window never seem to line up perfectly. The crowds are listed as “sometimes,” so you might have some company, but it’s a fairly exposed reef, so it can handle a few. The consistent swell direction (SSW) matches the optimum direction for the spot.
So, to wrap it up: the whole 16-day window has surf, but it’s a long grind of “good enough” days. The clear winner is the 22nd of September for the big-swell crew, and the 18th of September morning for a cleaner, smaller session. The first week is all about 6ft+ waves with side winds. If you’re a beginner, stay away from the 8ft+ days. If you’re an expert, circle the 22nd on your calendar.
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.
