The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
We’re focusing on Ekas-Inside, a sheltered reef break that’s got a bit of a pulse running through it for the whole 16-day window. The water’s sitting at a warm 79°, which is pretty much bang on average for this time of year, so no surprises there.
The pattern kicks off straight away. Tuesday the 8th, we’ve got a solid 7ft swell from the SSW at 13 seconds, which is a nice long-period groundswell. The combined energy is a hefty 2803 (moderate to strong), and with a cross-off wind from the SSE, it’ll be clean. This is a fairly consistent little reef, so expect some fun waves. Crowds can show up sometimes, but with a sheltered setup and a beginner-friendly rating, it’s a good spot for a wide range of surfers.
As we move through Tuesday afternoon and into Wednesday the 9th, the swell ticks up a touch. Wednesday morning hits 8ft from the SSW at 16 seconds (energy 3455). That’s getting into the size where beginners might want to be careful, but it’s still manageable for the crew with a bit of experience. The cross-off wind holds, keeping the surface clean.
Thursday the 10th drops a bit to 6ft in the morning, but the period is still 15 seconds, so the waves will have some shape. The energy is still moderate at 2151. Friday the 11th sees the wind pick up a little, with a fresh breeze at 19 mph in the afternoon, though still cross-off. The swell rolls through the weekend at 5ft to 6ft, with the same reliable SSW direction.
Now, the real standout for the whole run is shaping up for Wednesday the 23rd. That morning, we’re looking at an 8ft swell from the SSW, but with a 19-second period – that’s very long period groundswell. The combined energy jumps right up to 4842 (strong). The wind is SSE at 12 mph, cross-off, so the face will be clean. This is the one to circle on the calendar. It’s a bit further out, so treat it as a promising look, but if that holds, Ekas-Inside is going to be absolutely pumping. That long period might make it a bit straight on a beach break, but for this reef, it’s money.
The days leading up to that are solid too. The 21st has a gentle breeze and clean conditions with 5ft swell, and the 22nd sees a weird mix with a 3ft, 22-second period swell in the morning that’s got a surprising 1209 energy, but the afternoon picks up to 5ft with a 21-second period and 2750 energy – the wind is cross-shore though, so there’ll be a bit of chop. But it’s the 23rd that’s the real winner.
For the rest of the second week, the swell stays in the 5ft to 6ft range, winds are light to moderate and cross-off, so it’s consistent but not epic. The 20th of September, for example, is a nice 6ft morning with clean conditions. It’s a long run of surfable days, but only the 23rd looks like a true standout.
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.

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.
