The Lowdown

G’day, Rusty here. Let’s have a look at what’s shaping up at Ekas-Inside. This is a sheltered reef break, so it doesn’t cop the full force of the ocean, and that’s going to be the story for a while. The water temp is sitting at 79°, which is pretty much normal for this time of year, nothing wild there.

Right now, we’ve got a solid groundswell rolling in from the SW, but honestly, the conditions are just not coming together. The wind is cross-off from the SE, which isn’t terrible, but the whole stretch from Sunday the 13th through to Thursday the 17th is filled with “marginal” calls. The swell is hanging around 6 ft to 7 ft, with periods between 14 and 18 seconds – that’s a long period, meaning proper groundswell energy. For a reef setup like this, that should be good, but the combined swell energy is strong, between 1329 and 2887, and it’s just not clicking with the tides or something. Nothing worth paddling out for.

Friday the 18th morning shows a bit of promise. Swell drops to 6 ft from the SSW, period still a solid 14 seconds, and the wind eases right back to a light breeze at 6 mph. Combined energy is moderate at 1107, and the forecast says “expect very good surf conditions.” That’s the first real glimmer. Still, the rating is only moderate, so don’t expect perfection.

Saturday the 19th is a step down again. Swell fades to 4 ft in the morning with light winds, but the energy drops to 908. It’s small and clean, but nothing to write home about.

Then we get to Sunday the 20th of September. This is where it gets interesting. Morning sees a 7 ft SW groundswell with a 16-second period, light SE winds at 9 mph, and combined energy jumps back up to 2050. The call is “excellent surf conditions for experienced surfers.” That’s the standout. At 7 ft, it’s getting solid for a reef, and with that long period, it’ll have plenty of punch. The wind is light and cross-off, so it’ll be clean. This is the one to aim for.

The week after that has some size, but the consistency drops. Monday the 21st still has a 6 ft SW swell and light winds, with very good conditions expected. Then Tuesday the 22nd falls away to 5 ft in the morning and a weird 4 ft in the afternoon with a long 18-second period, but the energy is moderate and the calls are marginal.

The following Friday the 25th of September is another standout. Morning brings 7 ft from the SSW, 18-second period, light winds at 9 mph, and combined energy of 3247 – that’s strong. Again, “excellent surf conditions for experienced surfers.” The swell direction matches the optimum SSW for this break. It’s big and powerful, so leave the foam boards at home. Saturday the 26th holds similar size at 7 ft but the wind picks up a notch, still clean but not as perfect.

Overall, the best of the lot is Sunday the 20th morning and Friday the 25th morning. Both are for experienced surfers only, with strong groundswell, clean conditions, and light winds. The rest of the period is a mix of marginal or smaller days. There’s a gap of a few days in the middle of the first week where nothing really works. Get those two days marked.

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.
