The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next couple weeks.
Right off the bat, we’ve got a solid run of surf on the cards, but don’t get too excited just yet. The water temp is sittin’ at a very average 79°F for this time of year, so no surprises there – just your usual warm tropical bath.
The standout stretch kicks off on Saturday, September 5th, with Ekas-Outside offering up a consistent 7 ft of clean, lined-up SSW swell. The wind’s coming out of the SSE at 12–16 mph, which is a cross-off breeze – not glassy, but it’ll keep the faces reasonably tidy. The combined swell energy is pumping at 1449 (moderate to strong), so there’s plenty of push, but these waves are manageable for a confident beginner. The period sits around 14 seconds, which is a nice long groundswell – those sets will have some proper shape, and the longer gaps between them make paddling out a bit easier.
By Monday the 7th, we’re still seeing 7–7 ft SSW swell, same cross-off wind, and energy levels staying strong (1743–1894). It’s all very consistent, but the forecast notes keep mentioning “marginal surf” or “questionable tide conditions” – so don’t expect perfection every session, just solid, rideable waves.
Now here’s where it gets interesting. Come Tuesday the 8th, the swell period jumps to 19 seconds and the energy rockets up to 2681. That’s proper groundswell, heading toward 6 ft, but with that kind of period, Ekas-Outside (being a reef break) will handle it beautifully – long, grinding walls if the tide plays ball. Wednesday the 9th brings the biggest raw height at 8 ft in the morning, still with 16-second period and strong energy (3336). That’s pushing into expert territory – not one for the groms, but if you’ve got the skills, it’ll be a ripper.
The whole first week stays locked in with SSW swell, cross-off winds, and energy never dipping below 1385. There’s a real sweet spot on Tuesday the 8th and Wednesday the 9th – those are the two standouts. Big swell, long period, clean conditions. If I were you, I’d be marking those days.
Into the second week, the swell backs off a touch but stays very rideable. The direction swings more SW from Friday the 11th onward. Energy levels stay strong through the 13th and 14th (up to 3273), with swell heights hovering around 6–8 ft. Winds hold cross-off all the way, so it stays clean. The period drops to 14–16 seconds, still good quality, just not the same teeth as that mid-first-week spike.
Crowds at Ekas-Outside are marked as “sometimes” busy, so you might score a session with few others, but don’t count on having it to yourself every time.
By Friday the 18th of September, we finally see a breakout day: the morning shows 6 ft SW swell at 16 seconds with a gentle 9 mph cross-off breeze, and energy at 1420. The forecast actually calls it “excellent surf conditions for experienced surfers” – that’s a proper standout, especially after a lot of “marginal” notes. This one’s worth circling on the calendar, even if it’s over a week out.
The last few days (19th and 20th) hold steady at 6–7 ft with consistent cross-off winds, and the final Sunday morning delivers a 4 ft swell with a very long 21-second period – that’s a real slow, powerful groundswell, perfect for a reef like Ekas-Outside, though the smaller size means it won’t be as punchy.
Bottom line: if you can surf, the best bang for your buck is Tuesday the 8th and Wednesday the 9th – big, clean, long-period groundswell. Otherwise, there’s surf almost every day, just not all of it will blow your mind.
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.
