The Lowdown
Alright, Rusty here again. Let’s break it down for Ekas-Outside with the numbers you might be more used to.
The water’s about 79°F, pretty standard for this time of year. The pattern is a long run of south-west to south-south-west groundswells, with periods that mostly sit in that 14 to 16 second range—strong, proper lines for this reef.
Wind is steady from the south-east as a cross-off breeze through most of the outlook. It’s gonna keep the surfaces clean and the waves looking sharp. Not glassy, but a consistent cross-off is about as good as you can ask for here.
Monday the 14th and Tuesday the 15th kick off with swell around 6ft from the SW, period at 15-16 seconds. That’s solid. Combined energy is in the moderate range, around 1500 to 1900. Clean but not epic—solid everyday surf.
Wednesday the 16th morning and Friday the 18th are a step up in quality. Lighter wind, about 9 mph, still cross-off, and the swell holds around 6ft. The call is for “very good surf conditions” on those sessions. That’s your early pick.
The big standout, the one you don’t miss, is Sunday the 27th. The afternoon brings a 10ft swell from the SSW with a massive 20-second period. Combined energy is 7704—that’s strong. Wind is a light 9 mph from the SE, clean. That’s a powerful, dangerous wave for experts only. Monday the 28th stays big at 8ft to 10ft, with similar period and energy between 4120 and 5430. Another day for the experienced crew.
Surf runs every single day from the 14th to the 29th. No gaps. But for the best of the best, put your focus on Sunday the 27th and Monday the 28th. Big, clean, and powerful.
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.
