The Lowdown

Righto, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

We’ve only got one spot in the frame: Ekas-Outside. It’s a reef break that’s fairly consistent and fairly exposed, and the optimum swell direction is SSW. There’s no surf on offer right now, but don’t stress – the first waves roll in on Saturday the 12th.

Overall Pattern

We’re looking at a long run of clean, cross-off wind from the ESE/SE/SSE, which is a nice setup for this reef. The swell hangs around the 5 ft to 8 ft mark for the first ten days or so, with mostly 14 to 18-second periods – that’s proper groundswell energy. The combined energy values early on are in the 1000s (moderate to strong), building into the 2000s and 3000s later. It’s a decent stretch, but nothing is screaming “best ever” until the second week.

Saturday 12th – Sunday 13th September

The weekend kicks off with Saturday morning seeing 5 ft of SW swell at 14 seconds, combined energy of 1826. Water temp is sitting at 80°, which is a normal 0.4° below average for this time of year – nothing weird there. The wind is a consistent 12 mph cross-off ESE, keeping things clean. It’s okay, but the forecast calls it “marginal,” so don’t expect perfection. By Sunday morning, the swell bumps up to 6 ft from the SW, period jumps to 18 seconds, and energy hits 2703 – a nicer pulse. Still, the wind remains cross-off, so it’s clean but not glassy.

Monday 16th – Saturday 19th September

Through the week, the swell holds in the 4 ft to 7 ft range with periods dropping slightly to 13-15 seconds. Winds stay cross-off from the SE/SSE, 9-16 mph. It’s consistent, but nothing is a standout. A bit of a flat spot mid-week – Thursday and Friday afternoons drop to 4 ft and 5 ft, with lower energy in the 800-900 range (weak). You’d still get a wave, but it’s not firing.

THE STANDOUT: Sunday 20th – Monday 21st September

Now we’re talking. Sunday the 20th morning sees 7 ft of SW swell at 16 seconds, and by the afternoon it’s 7 ft with combined energy of 2330. The wind drops to a gentle 9 mph cross-off from the SE. The forecast calls it “excellent surf conditions for experienced surfers” – and I’d agree. That’s the best combo of size, energy, and clean conditions in the whole run. Monday morning keeps the 7 ft going with 1651 energy. This is your window. It’s big enough (over 5 ft) that beginners might want to sit it out, but for anyone who’s comfortable, this is the pick.

Tuesday 22nd – Wednesday 23rd September

Tuesday drops back to 6 ft, but Wednesday the 23rd brings another solid pulse: 8 ft – 8 ft from the SSW with periods of 16-17 seconds and energy up at 3362. Winds are 12 mph cross-off, so it’s still clean, but expect solid, powerful waves. This is expert territory over 8 ft on the afternoon session. Crowds are “sometimes” at Ekas-Outside, so you might get a few others out, but nothing like a full-on circus.

Thursday 24th – Friday 25th September

Thursday eases back to 7 ft, but Friday the 25th is a long-range wildcard. Morning swell is 6 ft, but the period hits 21 seconds – that’s very long period groundswell – and combined energy is 4190. The afternoon jumps to 10 ft at 19 seconds with energy of 6299! That’s heavy, powerful swell. For a reef break, this long-period energy will wrap in nicely, but 10 ft is expert-only. The winds are light to moderate cross-off, so it’ll be clean, just massive. Worth noting for the experienced crew.

Saturday 26th – Sunday 27th September

Saturday stays on 10 ft from the SSW at 17 seconds, energy still over 4000. By Sunday it drops to 7 ft. The wind stays cross-off, so it’s still good, but the size is fading.

The long-range stuff (from Monday 21st onwards) is promising but less certain – forecasts can shift, but the signals are there for some proper sessions.

Overall, the best bet is Sunday the 20th and Monday the 21st for that sweet spot of size, clean wind, and excellent conditions. The 23rd and 25th are for the experts only. There’s nothing for beginners in this run after the first weekend.

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.
