The Lowdown
Alright folks, Rusty here with the lowdown for Ekas-Inside.
We get started on Monday afternoon, August 24th. There’s a solid SSW groundswell running 6 feet with a long 16-second period. Combined energy is reading 1742, so there’s real meat on the bone. Wind is a fresh SE cross-off, keeping it glassy. Water temp is 79°F, right on average for the season. This is a sheltered reef that’s friendly for beginners, and crowds are just sometimes, so you’ve got room.
Tuesday the 25th keeps the swell at 6 feet from the SSW and SW, with those long periods. Winds stay cross-off, so it’s clean and rideable all day.
Wednesday the 26th holds at 6 feet, period drops to 14 seconds but it’s still fun. Easygoing, with moderate cross-off breeze.
Thursday the 27th drops to 4 feet in the morning with a 16-second period. That long period on a reef is good, but the afternoon turns cross-shore and bumpy, so surf early.
Friday the 28th of August is the big one. We get 8 feet of SSW groundswell with a 17-second period. The combined energy is 4123 – powerful stuff. This is for experts only. Winds are clean cross-off, and the surface will be smooth. If you’re skilled, this is your day.
Saturday the 29th drops to 7 feet from the SW, still solid, but a step down from Friday.
Sunday the 30th is smaller at 5 feet, but Monday the 31st afternoon brings a pumped-up 6 feet with a 19-second period – real groundswell energy (2875). Winds are light and cross-off: clean surf.
September starts strong. Tuesday the 1st and Wednesday the 2nd both have 7 to 7 feet SSW to SW swells, with 16 to 17-second periods. Wednesday afternoon is flagged as excellent for experienced surfers.
The second week tapers a bit. Thursday the 3rd is 6 feet, and Friday the 4th drops to 5 feet with fresh winds – skip Friday, it’s poor.
Saturday the 5th is small, 4 to 3 feet, but Sunday the 6th and Monday the 7th bring a fresh pulse back up to 7 to 7 feet SSW swell. Mornings are clean, afternoons get a bit side-shore.
We finish Tuesday the 8th with 6 feet and cross-off winds in the morning – a clean end.
Best on offer? Friday the 28th of August – that 8-foot, 17-second groundswell is the heavyweight. Wednesday the 2nd of September is another gem for the experienced crew. Most of the window has clean winds, and those long-period swells will be groomed by the reef. Just know the bigger days are for the experts.
Rusty.

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.
