The Lowdown
G’day, Rusty here, and I’ve got a proper look at the swell ahead for Ekas-Outside. This is a reef break that’s pretty exposed to the south-west, and it’s pulling in a solid, consistent south-southwest groundswell for the whole 16-day window. The water temperature is sitting at 79°, which is dead average for this time of year, so no surprises there. The standout is the first couple of days – Monday 10th and Tuesday 11th – with a big, powerful swell that’s got some serious energy behind it. After that, the size drops a touch but stays rideable right through to the end of the month.
We kick off on Monday 10th August with a strong 10ft swell from the SSW, pumping in at 18 seconds and a massive combined energy of 5340 – that’s proper grunt. The wind is a cross-off from the SSE at 12 mph, keeping the surface clean. This is a cracker, but with 10ft, it’s getting into the zone where only experienced surfers should be out. Tuesday 11th hangs onto the same size, 10ft from the SSW, with periods of 17 to 19 seconds, and energy climbing to 7475 on Tuesday afternoon. Winds stay cross-off and clean. This is the best on offer – big, clean, and powerful. Wednesday 12th drops to 7ft, still clean, but the energy drops too. The rest of the week into the weekend holds 7ft to 8ft from the SSW, with periods around 14 to 17 seconds, and moderate cross-off winds. It’s consistent, but nothing matches the opening punch.
The second week from Monday 17th August sees the swell dip a little – 5ft to 5ft early on, then building back up. Monday 18th is a nice pick: 5ft from the SW, 16 seconds, with a gentle breeze from the ESE at 9 mph, and the wave comment calls it excellent for experienced surfers. That’s a clean, fun day. From Wednesday 19th onwards, the swell builds again, hitting 8ft on Thursday 20th and again on Monday 24th. The 24th has a 8ft SSW swell, 17 seconds, and combined energy of 4049 – that’s a strong return. Winds stay cross-off, so it’s clean throughout. The long period swell (over 15 seconds) means the waves will have good shape and energy, but at a reef break like this, it should handle that nicely.
Overall, the real standout is the Monday 10th to Tuesday 11th window – big, clean, powerful SSW groundswell. If you’re an experienced surfer, that’s the call. The rest of the run is solid, with another good spike around Monday 24th. Crowds can be an issue here sometimes, so keep that in mind. No other breaks in the data, so this is the whole show.
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.
