The Lowdown
G’day, Rusty here. Let’s talk about Ekas-Inside. This reef break is a sheltered little number, best with a solid SSW groundswell. The water’s sitting at 79°, which is about normal for this time of year, so nothing wild there.
We’re looking at a bit of a wait, though. Starting Sunday the 23rd of August, there’s some swell around 6 ft from the SSW with a long 15-second period, and the combined energy is a beefy 2635. That’s strong wave energy. But the wind is a cross-off from the SSE at 16 mph, not ideal, and the comments flag questionable tide conditions. It’s clean-looking on the surface, but the quality’s not quite there. The real problem is that pretty much every day through the rest of August is flagged as “marginal” or “poor” – the wind stays cross-off, the swell direction is okay but the conditions don’t line up right. Monday the 24th through Sunday the 30th are all a bit of a write-off, with decent-sized swell but that cross-off wind and tide issues.
Then we hit a proper stand-out. From Monday the 31st of August through to Wednesday the 2nd of September, things start to come together. Monday morning has 4 ft from the SSW with a very long 19-second period, combined energy at 1383 (moderate). Monday afternoon bumps up to 5 ft, 17 seconds, energy 1926. Tuesday the 1st of September is the real gem: morning sees 6 ft from the SW, 17-second period, energy a solid 2318. Wind is SE at 13 mph, still cross-off, but the swell direction matches the optimum SSW, and the period is long enough to push in clean lines over the reef. It’s not glassy, but it’s consistent and the wave comment suggests it’s the best on offer, with a decent score. Wednesday the 2nd is similar: 7 ft from the SW, 16-17 seconds, energy around 2334. For the more experienced surfer, this swell size is manageable – it’s not too big for a reef, just about right.
After that, things fade. Thursday the 3rd has 6 ft but the energy drops to 1560, and by Friday the 4th it’s poor surf with strong wind. There’s a little pulse again on Saturday the 5th of September with 7 ft from the SSW, 16 seconds, energy 2096, but again the cross-off wind and tide issues linger. Sunday the 6th and Monday the 7th are smaller and fading.
Honestly, the best window is Monday the 31st of August through Wednesday the 2nd of September. That’s where the longer-period SSW groundswell lines up best with the optimum direction, the energy is moderate to strong, and the wind, while not offshore, isn’t ruining it. This is a fairly consistent reef, so the blanks we’re seeing early on are just a waiting game. Keep an eye on that Tuesday morning – it’s the pick of the lot, but remember, long-period groundswell like that 17-second stuff can be a bit walled-up on a reef, so pick your take-off spot. The water’s warm, the crowds are “sometimes” here, so you might get a few out but nothing mental.
That’s it from me. Stay stoked.
Rusty.

Information about the Ekas-Inside Surf forecast
The above surf forecast table for Ekas-Inside provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ekas-Inside can be found by selecting the local surf guide option on the grey menu. Our Ekas-Inside 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-Inside) 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-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.
