The Lowdown
Alright folks, Rusty here. We’ve got a solid run of swell heading our way for Ekas-Outside, so let’s get into it.
The overall pattern is a long stretch of consistent, clean SSW to SW groundswell. The wind is stuck in a cross-off SE or SSE flow for the whole 16 days, which is a bit of a bummer – it’s not properly offshore, but it’s keeping the surf clean. The real story is the size and the energy. This isn’t a small window; it’s a proper run of moderate to strong wave energy. The combined energy of all swells hitting the reef is in the thousands – we’re talking 2699 on Wednesday morning, climbing to 3755 Thursday afternoon, so there’s some serious power behind these waves. This is a reef set-up, so that long-period groundswell (14 to 18 seconds) is going to line up really well, giving you proper shaped waves and longer lulls between sets.
The week starts off from Wednesday, 12 August, with a solid 7ft swell from the SSW. The wave energy is strong (2699). The wind is a cross-off SE at 25 km/h, so the faces will be clean. It’s a beginner-friendly reef, but at this size, it’s getting into more challenging territory. Thursday, 13 August, is the pick of the early week. The swell jumps to 8ft from the SSW, with massive energy (3755) and a 16-second period. The wind is a touch lighter at 20 km/h from the SSE. This is big, powerful, and clean – a real standout for experienced surfers. The water temp is likely about average for this time of year, so nothing strange to report there.
We’ve got a bit of a drop-off in size by Monday, 17 August, but the swell direction starts to shift to the SW. Then, Tuesday, 18 August, things get interesting. The morning brings a 5ft SW swell with a 16-second period. The wind drops right back to a light breeze at 10 km/h from the ESE. The wave energy is still high (2362), and the conditions are described as excellent for experienced surfers. This is a standout morning – smaller, but glassy and perfectly lined up.
The following week looks like it keeps the momentum. Wednesday, 19 August, is a big one. The morning shows a 8ft SW swell with an 18-second period (very long period groundswell) and energy at 3401. The wind is a gentle 15 km/h. This is a classic, powerful groundswell that will be absolutely cranking on the reef. Further out, the 23rd of August (Sunday) shows a spike in energy with a 7ft SSW swell and a 20-second period, pushing the energy to 4897. That’s a seriously strong, long-period swell, but it’s a long way out, so treat that as a promising, but less certain, prospect.
Crowds at Ekas-Outside are a sometimes thing, so you might get some company, but it’s not a zoo. The consistency is described as fairly consistent, which is spot on for this window.
So, the best on offer? Thursday morning, 13 August, for the big, powerful 8ft SSW swell with clean conditions. And Tuesday morning, 18 August, for the smaller, glassy, and perfectly shaped 5ft SW swell. Those are your two standouts.
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-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.
