The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
The main show is at Ekas-Inside, a nice sheltered reef break. It's a consistent spot that's pretty forgiving for beginners, but it's rated as a "fairly consistent" break, so don't expect it to be absolutely pumping every single day. The water temperature is running about what you'd expect for this time of year, so no nasty surprises there.
Right off the bat, from Sunday morning the 6th, we've got a solid 7 ft SSW swell rolling in with a period of 14 seconds. That's a proper groundswell, and it's got some good energy behind it (1988). The wind is a cross-off from the SSE, which is a decent angle for this spot and will keep the surface clean. The ride is a bit of a sneaky one, but it's a solid 3 out of 10 for the morning. The afternoon drops a touch to 6 ft.
Monday the 7th looks similar with a 7 ft SSW swell in the morning, dropping to 7 ft in the afternoon. It's still clean, but the scores are a little lower. The combined energy is strong (1817 for the morning).
Tuesday the 8th, the wind swings more cross-shore from the S, and the wave comment mentions a cross-chop, so it's going to be a bit messier. The swell is still there at 7 ft in the morning, but the quality drops off. The afternoon has a very long period of 18 seconds, which is a classic sign of a powerful groundswell. The energy is massive (3585), but with that cross-breeze, it's more of a test of your patience than a clean session.
Now, the real standout for the first week is shaping up for Wednesday the 9th. The morning brings a 8 ft SSW swell with a 16-second period. The combined energy is cooking at 3569. The wind is cross-off from the SSE, so the surface will be clean. That's a big, powerful swell for this sheltered spot. Afternoon gets a bit of a cross-wind, but the morning window looks like the pick of the first week.
The rest of the first week and into the second week is a bit of a mixed bag. The swell stays around the 5 ft to 7 ft range, mostly from the SW. The wind is generally a cross-off from the SE, which keeps things clean. The energy levels are moderate to strong, with three-digit numbers like 1927 and 2425. There's a storm risk on the afternoon of the 13th, so keep an eye on the sky.
The real promise, though, is in the second week. We're looking at Saturday the 19th and Sunday the 20th. On Saturday the 19th, we've got a 7 ft SW swell in the morning, building to 8 ft in the afternoon. The energy is ramping up (2352 and 2709). The wind is a gentle breeze from the SSE, which is almost glassy. That's a long-range call, so it's a bit less certain, but it's looking like a beauty.
But the absolute best of the entire forecast is staring us right in the face for Sunday the 20th. The morning swell hits 8 ft from the SW with a 15-second period. The combined energy is a massive 3277. The wind is a clean cross-off from the SSE. This is a big, powerful swell for a sheltered reef, and it's going to be clean. The afternoon holds the same size and energy. If you can only surf one day in the next two weeks, this is the one to aim for.
After that, Monday the 21st drops back down to 7 ft and the energy fades.
So, the pick is clear: Sunday the 20th of September is the day to clear your calendar. The Saturday the 19th is a solid backup. The first week is all about early morning windows, especially Wednesday the 9th.
Rusty, signing off.

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.

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.
