The Lowdown
Alright, Rusty here. Let’s break down the Ekas-Inside outlook.
Straight away, this is a long, steady run of solid groundswell with real consistency, but the wind plays a steady hand – cross-off from the SE to SSE nearly the whole way. Not glassy, but clean enough to work with. The water sits at 79°F, just about average for the year.
Surf starts Thursday, September 10. Ekas-Inside is a sheltered reef, so it needs a bit of push, and it’s getting it. Thursday morning has a 6ft SSW groundswell with a very long 15-second period and combined wave energy at 2142 (strong). The wind is cross-off from the SE at 16 mph – not perfect, but the surface holds clean. Because it’s beginner-friendly, but the swell size pushes past 5ft, it might feel a bit much for a raw beginner. Afternoon bumps to 7ft. The swell period stays long, and the energy stays up. The standout here is the sheer longevity of the deep, long-period energy.
Friday (Sep 11) holds 7ft to 6ft SW groundswell, still 16 seconds. The wind stays around 12–16 mph, never light, but the face stays clean. Saturday (Sep 12) drops a bit to 5ft then 5ft, still long period. Sunday (Sep 13) ramps back to 7ft in the afternoon (SW 17s), with combined energy at 2823 – that’s a powerful pulse. That’s probably the biggest of the first week.
Second week compresses fast: Monday Sep 14 through Wednesday Sep 16 holds steady at 6ft to 7ft, periods 15–16 seconds. Winds stay SE at 12 mph, clean. Friday Sep 18 looks interesting – morning dips to 4ft but afternoon returns to 6ft with the same long period, and the report calls for very good surf conditions – that’s the bright spot. Weekend Sep 19–20 drops to 5ft–5ft. Then Monday Sep 21 pushes back to 7ft, building to Thursday Sep 24 with 8ft on morning and afternoon (SSW 15s, energy at 2613). That Thursday is another proper day. Friday Sep 25 still has 7ft but periods drop to 14 seconds.
Standout sessions: Sunday Sep 13 afternoon (7ft, SW 17s, 2823 energy) and Thursday Sep 24 morning (8ft, SSW 15s, 2613 energy) are the biggest, most powerful. But neither has lulls in the wind – it’s cross-off the whole way. That’s the trade-off. Crowds are “sometimes,” so you’ll likely have company, but not packed. For a beginner reef, the consistency and long period produce good shape.

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.
