The Lowdown
G’day, it’s Rusty here.
Okay, let’s break this down. The forecast for Ekas-Outside (Bali) is a solid block of clean, powerful groundswell for the next couple of weeks. Water temp is 79°, which is about normal for this time of year.
It all starts on Saturday the 8th with a 8ft SSW swell at 16 seconds, packing a punch with energy at 3303. That’s a beefy wave for the reef, but a cross-off SE breeze at 12 mph will keep it looking tidy. It’s got beginner-friendly ratings, but at that size, it’ll be a handful. The tide might not be perfect, so don’t expect it to be easy.
Sunday the 9th holds steady with 7ft at 16 seconds and the same cross-off wind. Still pushy, but consistent. Monday the 10th, the morning drops to 6ft but the period stretches out to 19 seconds – that’s a long, racy groundswell that can be a bit straight on a beach break, but on a reef, it’s going to be smooth and long. The afternoon, though, jumps right up to 10ft at 18 seconds, with energy climbing to 5340. Now we’re talking.
Tuesday the 11th is the big one for the first week. Morning is 10ft at 17 seconds, but the afternoon is the standout: 10ft at 19 seconds, with energy exploding to 8106. That’s serious, heavy water. Wind is still a clean cross-off at 16 mph. This is a big day – well over 8ft, so it’s experts only. That’s the one to chase.
Wednesday the 12th drops back to 6ft and then 7ft, the energy falls off, and the period shortens to 14-15 seconds. It’s still surfable, but the juice is gone. Thursday the 13th brings the size back up to a solid 10ft, energy back over 5000, but the period is a bit shorter. Still a heavy, grinding reef.
Friday the 14th to Sunday the 16th, we’re in the 6ft to 8ft range, with periods around 15-17 seconds. It’s consistent and clean, just not as potent.
Monday the 17th, the wind freshens to 19 mph, and the size drops to 5-6ft. The energy takes a real hit, down to 943. It’s still clean, but it’s the weakest stretch.
Tuesday the 18th is similar, with a little more size in the afternoon at 7ft, but the fresh breeze is still there. The direction shifts slightly to the SW.
Now, the second true standout. Wednesday the 19th brings back the size to 8ft with a longer 18-second period, and the energy is back over 4000. It’s a solid, powerful day. But the gem is Thursday the 20th morning. The wind drops right off to a light 6 mph breeze, the swell is a clean 8ft at 16 seconds from the SW, and the report says it’s excellent for experienced surfers. That’s the cleanest, most manageable size, and with that light wind, the reef will be glassy. That’s a morning to mark down.
Friday the 21st pushes back up to 10ft, energy over 5000 again, but the wind is stronger. The weekend of the 22nd and 23rd fades out, with the wind picking up to 19 mph on Sunday and the swell dropping to 6ft. The run ends pretty quietly.
So, the two standouts are Tuesday afternoon (the 11th) for pure power and energy, and Thursday morning (the 20th) for the cleanest, most manageable size with the lightest wind. The rest is a consistent run of good waves, but those two are the ones to plan around.
Crowds at Ekas-Outside can be a thing sometimes, so get out there early for those key sessions.
That’s all from me. Keep it salty.
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.
