The Lowdown
Alright, Rusty here. Let’s talk about the surf for the next couple of weeks. We’ve got a solid run of swell from the SSW, but the wind is a steady cross-off, keeping the waves clean but not glassy. The water temp is right where it should be for this time of year.
The main break is Ekas-Inside. It’s a sheltered reef, and it’s going to be a consistent player. The swell energy is strong, with a four-digit reading (3689) on Monday morning, August 10th, with a 6ft SSW swell at a very long 19-second period. That’s proper groundswell. For a beginner-friendly reef, that long period and bigger size (10ft later in the day) means it’s more of a challenge, but for an experienced surfer, the shape will be there. The wind is a steady 12 mph cross-off, so the surface is clean.
The standout session is shaping up for Tuesday, August 11th, in the afternoon. That’s a 10ft SSW swell, an 18-second period, and a massive combined energy of 7477. That’s a lot of power. The wind is still cross-off, but the scale of the swell is the real story. This is expert territory at that size. If you’re solid on a reef, that’s the one to chase.
For the rest of the first week, the swell drops a bit but stays in the 6ft to 8ft range, with the same cross-off wind. The energy stays strong (1933 to 3634), so you’ll have plenty of push. The period drops to the 14 to 17-second range, which is still decent groundswell.
Heading into the second week, from August 18th onward, the swell gets a bit smaller and the wind picks up. August 19th sees another pulse of 8ft SSW swell with a 17 to 18-second period and energy around 4100 to 4322, but the wind is up to 19 mph. It’s still cross-off, so it’s paddleable, but it’s going to be a fight. The consistency for the whole window is fairly consistent, so you won’t get skunked, but the quality is marred by that constant moderate breeze.
For the beginners, the smaller days around the 5ft mark (like the 17th and 18th) are your best bet. Once it’s over 8ft (like on the 11th, 19th, and 20th), it’s for experts only.
Overall, the best bet is Tuesday, August 11th afternoon for the size and power, but be ready for a heavy wave. The rest of the window is solid, consistent surf, but nothing that’s going to blow your mind.

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.
