The Lowdown
Alright, Rusty here. Let's have a look at what's on the table. The water's sitting at 80° which is basically just your average for this time of year – no surprises there.
Alright, we kick things off this Friday morning, the 14th of August, at Ekas-Inside. We've got a solid groundswell rolling in from the SSW, hitting about 7ft at a long 16 seconds. That's a lot of energy pushing in. The wind is a cross-offshore from the SE at 12 mph, which is alright, keeps the surface clean enough, but it's not glassy. It's a bit of a mixed bag though; the conditions are rated as marginal, so don't expect perfection. The afternoon drops a touch to 7ft.
Saturday the 15th is more of the same, good swell size (7ft) and very long period (17 seconds) – that's proper groundswell energy. Cross-off wind again, but it's a gentle breeze in the morning which is nicer.
Now, Sunday the 16th morning is where it gets interesting. The data says it's *excellent for experienced surfers*. Swell is about 7ft from the SSW, period at 16 seconds, and the wind is a light cross-off at 9 mph. This is a standout window for the crew that knows what they're doing on a reef.
We drop off a bit Monday the 17th; the swell backs down under 7ft.
The Real Standout
Hold onto your board, because Tuesday the 18th morning is the pick of the entire forecast. The wind goes true offshore, baby! Gentle breeze from the ESE at 9 mph. That'll smooth out the 4ft SSW groundswell like glass. The period is a strong 16 seconds, and the energy spikes high for that size, suggesting a clean, powerful wave despite the lower height. This is the session to circle on your calendar – clean, lined-up reef waves with no bump.
The swell builds again for the second half of the month, but the wind stays cross-offshore. Wednesday the 19th pushes up to 8ft SW at 18 seconds – that's huge, powerful, proper energy. Thursday the 20th hits 10ft SW, same 16-second period, and even more energy. At 10ft, that's expert territory only. It'll be a big, heavy wall. This stretch of big swell runs through until the 22nd of August, riding from 8ft to 10ft.
After the 22nd, the swell slowly trickles down through the end of the month. You'll still get waves, mostly in the 3ft to 5ft range, with periodic bumps of better energy, like the 5ft on the 29th with a 16-second period. The wind stays as a cross-off the whole way through. Crowds here can be an issue sometimes, so get in early.
So the two main calls: Tuesday morning, August 18th for the cleanest, most user-friendly conditions on a decent sized swell. Then Wednesday the 19th through Friday the 21st for the big, powerful groundswell that'll suit a more experienced crew who are happy to handle some serious energy.
Rusty.

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-Inside 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.
