The Lowdown
G’day, Rusty here, and I’ve been staring at the charts for Ekas-Inside. We’ve got a solid 16-day window ahead, but it’s not all clean winners. The pattern is a consistent, long-period SSW groundswell running through the whole period, but the wind is mostly cross-off, which keeps it rideable, but not always perfect. The standout moment is definitely Friday morning, the 7th of August, when we get a gentle offshore breeze. That’s the one to circle.
Let’s start with the first real action. Wednesday morning, the 5th of August, we’ve got 6 ft of SSW swell at a long 15 seconds, but that 16 mph SE cross-off wind keeps it from being a gem. The combined energy is already strong (1562). Through Thursday the 6th, the swell builds to 7 ft, period hitting 17 seconds, and the energy climbs to 2763, but it’s still cross-off, so it’s a bit of a wrestling match.
Then we hit Friday morning, the 7th of August. This is the best on offer. The swell is 8 ft from the SSW, period a generous 17 seconds, and the wind swings to a light 9 mph offshore from the ESE. That’s the key. The combined energy is a massive 3321, and the wave comment says “excellent surf conditions for experienced surfers.” This is a step up. The water is about average for the time of year, so no temperature surprises. For a reef break, a long-period groundswell like this will draw lines beautifully, but the 8 ft height is too big for beginners, so it’s a session for the crew who know what they’re doing. The break is fairly consistent, but with that offshore wind, expect it to be clean. Crowds are “sometimes” here, so you might have a few others out, but it’s worth it.
Saturday the 8th and Sunday the 9th hold similar size (8 ft and 7 ft) but the cross-off wind returns, so it’s a bit lumpier. The energy stays high (3376 and 2330). Monday the 10th drops to 5 ft but the period is a very long 20 seconds, and the energy is still strong (2926). Tuesday the 11th sees a spike to 10 ft, with a 17-second period and energy at 5250. That’s big, powerful, and only for experts. The wind is cross-off, so it’s not an easy paddle.
We then have a gap of several days, from the 12th to the 17th, where the swell is 6 ft to 8 ft, and the energy is in the 2000-3000 range, but the wind stays cross-off. The wave comments are mostly “marginal surf forecast or questionable tide conditions.” It’s not a write-off, but there’s nothing that screams “go now.” A few mornings on the 13th (7 ft, 16 seconds, light breeze) and the 20th of August (8 ft, 16 seconds, light breeze) have offshore wind and excellent conditions for experienced surfers, but they’re further out.
The second week shows promise, but it’s less certain. Thursday morning the 20th of August has 8 ft from the SSW at 16 seconds, with a light SSE breeze and excellent conditions for experienced surfers. The energy is 3319. That’s a solid long-range standout, but it’s two weeks away, so keep an eye on the charts.
The bigger swells (over 8 ft) are only for the experts. The 10 ft days on the 11th, 18th, and 19th are powerful and require skill. The 20th of August is a promising one to watch.
Rusty out.

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.

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.
