The Lowdown
G’day, Rusty here. I’ve been giving the charts a good looking over.
Okay, so it’s all about Ekas-Inside for the next couple of weeks. A sheltered reef break, good for learners, and the water temp is about what you’d expect for this time of year.
The fun starts on Tuesday, August 11th with a solid 10 ft south-southwest groundswell and a really long period of 17 to 19 seconds. The wave energy is massive – 4949 to 7477 (very strong). This is the standout day. The wind is a cross-off from the SSE at 12 to 16 mph, which keeps the faces clean. At this size, it’s for experienced surfers only, not beginners. The lines on that reef are going to be proper.
On Wednesday, 12th, the swell drops to 6 ft to 7 ft, with energy dropping (2225 to 1933 – moderate). Still cross-off wind. Thursday, 13th through Saturday, 15th holds at around 7 ft to 8 ft from the SSW, with periods of 15 to 17 seconds. Energy is moderate to strong (2672 to 3554). Clean, workable waves.
Sunday, 16th is similar but the energy eases. Monday, 17th sees the swell dip to 5 ft to 5 ft with a solid 14 second period. The wind eases to a lighter ESE at 9 mph. Energy is moderate (1073). This is a much nicer size for the beginners the spot is known for.
Then from Tuesday, 18th, the swell goes SW but it keeps coming. A new pulse on Wednesday, 19th gives us 8 ft at 18 seconds – energy of 3779 (strong). Looking further out, Friday, August 21st looks promising with another 10 ft SW swell at 17 seconds and energy of 5115 to 5378 (very strong). The wind is a cross-off at 12 mph. It’s a promising long-range call.
The swell hangs on through the weekend of 22nd-23rd, easing from 10 ft down to 7 ft. By Monday, 24th, there’s a weird one: 5 ft but with a very long 19 second period, giving an energy of 3363 – a lot of push for the size. That period might make it break a bit straight on the reef, so watch out. Tuesday 25th eases, and by Wednesday 26th, we’re down to 5 ft at 14 seconds with energy dropping to 1009 (weak). The run is done.
The standout is definitely Tuesday, August 11th for power and size. Friday, August 21st is a good bet further out, but keep your eye on it. The wind is always cross-off, never glassy, but clean enough. Because this spot is "fairly consistent" and a single reef, expect a few other people in the water.
Rusty.

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.

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.
