The Lowdown
Alright crew, Rusty here. Let's talk about what's cookin' at Ekas-Outside for the next couple of weeks. We've got a long run of solid, consistent SW groundswell on the way, but it ain't all smooth sailing – the wind is gonna be a persistent factor.
The whole pattern is built around a long-lasting, powerful SW groundswell that's already pulsing. The water's sitting at a nice 79°F, which is pretty much spot on average for this time of year, so no surprises there.
We're looking at a lot of days with moderate cross-offshore breezes from the SE and SSE. It'll keep the surf clean, but those 12 to 19 mph winds will have some push. The standout window kicks off on Sunday the 20th of September. Sunday morning brings a solid 7 ft swell from the SW with a 16-second period. The combined energy is strong at 2050 (moderate wave energy), and with a gentler 9 mph SE cross-off, the conditions are looking excellent for experienced surfers. This swell is a proper groundswell, so expect well-shaped, powerful lines. The long period will mean better gaps between sets, making the paddle out easier, but at a reef break like this, it's going to set up beautifully. It's a fairly consistent spot, so you won't be waiting around forever.
Then, the real highlight of the whole run looks to be Friday the 25th of September. The morning session is the one to circle. We've got a 7 ft SSW groundswell with a very long 18-second period pumping in, and the combined energy is ripping at 3247 (strong wave energy). The wind is a light 9 mph from the SSE, keeping things clean. This is prime, powerful groundswell for the reef. It's definitely expert territory at this size, but for those who can handle it, this could be the session of the trip. The afternoon bumps up to 8 ft and 18 seconds with a bit more wind, still a solid option.
Earlier in the run, Friday the 18th of September is a sleeper. A lighter 6 mph SE breeze makes for a glassy morning on a 6 ft SSW swell with a 14-second period. It's a bit smaller, but those light winds will make it super clean and fun for the better intermediate surfers.
Saturday the 19th morning is similar with light winds and a 4 ft SSW swell, but the period drops. From the 22nd onwards, we get a bit of a lull in size and quality, but it picks right back up.
Towards the end of the period, the swell runs out of steam. By Monday the 28th of September, we're down to a weak 4 ft SSW swell with a short 13-second period and a combined energy of only 542. The winds are still up around 12 mph, and it's not looking like it's worth the paddle. That's a clear sign the run is over.
So, to sum it up: the whole first week and a half is filled with solid, clean surf. The absolute best on offer is Sunday the 20th morning and Friday the 25th morning. Get on 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.
