The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the table at Ekas-Inside. We’ve got a long, clean run of days ahead, but not every session is gonna light your fire. The pattern is a steady one: mostly cross-off shores, clean surfaces, and a reef that’s in the mix most of the time.
Water sits right around a balmy 80°, pretty much where you’d expect for this time of year.
Starting off on Saturday the 12th, we’ve got a clean 1.6m (about 5ft) groundswell from the SW with a period of 14 seconds. That’s some solid, long-period energy hitting the reef, with a combined energy reading of 1826 pushing through. The wind is light and offshore – glassy faces for the morning. It’s a gentle start, but it’s on.
Sunday the 13th is where it steps up. Swell size jumps to 1.7m to 2.2m (6ft to 7ft), and the period extends to a very long 18 seconds. That’s proper deep ocean energy, and the combined energy hits 2875. That’s a lot of push for a sheltered reef. It’s going to be punchy, wavey, and will require some serious respect. Definitely in the expert-only zone for the bigger sets. Beginners stay on the beach.
Monday the 14th through Tuesday the 15th holds size around 1.8m to 1.9m (6ft to 6ft) and a period still in the mid-teens. Winds hold cross-off and clean, but the energy level starts to drop off by Tuesday afternoon. It’s still surfable, but that wow factor from Sunday will be gone.
The middle of the week, Wednesday the 16th to Friday the 18th, sees the swell ease back to 1.3m to 1.7m (4ft to 6ft), with period dropping too. The quality remains clean, but the punch is gone. Fun smaller waves for a cruiser board, but you won’t be sending it.
Now for the real standout window. Saturday the 19th and especially Sunday the 20th of September are the ones to circle. Sunday brings a solid SW groundswell of 2.3m to 2.4m (8ft to 8ft), with a steady 15 to 16 second period. Combined energy jumps back up to 2725. Winds are light and cross-off again. This is the classic reef setup for experienced surfers. Too big for beginners, but for the crew that knows the peak, this is the day to make plans.
Through the following week, the swell stays around 1.5m to 2.0m (5ft to 7ft), but the wind picks up from the SSE, putting a bit of bump on the water. Still rideable, but that silky smooth morning texture is harder to find.
If you’re picking your days, go big on Sunday the 20th. That’s the clear winner. Everything else is a solid, clean run with some worthwhile morning sessions until then.
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.
