The Lowdown
Alright, grab your board and let’s have a look at what’s coming down the pipe for the next couple of weeks. It’s a bit of a grind for a while, then things look like they might turn on. We’re talking about Ekas-Inside, a sheltered reef setup that’s going to need a bit of patience.
To start, the water is sitting at 79.3°, which is pretty much right where it should be for this time of year. Nothing weird going on there, just your standard tropical warm.
The next few days are going to test you. The swell is coming in from the SSW and SW, but it’s just not lining up cleanly. The wind is cross-offshore, which keeps the surface glassy, but the forecast keeps calling it marginal. It’s surfable, but you’ll be scratching for the good ones. Wednesday and Thursday have some chest to head-high sets, but it’s all a bit lumpy and unsure of itself. Honestly, it’s not going to be a classic. The water’s warm, it’ll be a fun splash, but don’t expect to be blown away.
By the weekend, the swell drops off a bit. We’re looking at smaller, less consistent waves. The energy is still there, but it’s weak. You’ll be on the longboard for sure. The wind stays cross-offshore, which is okay, but the whole thing is just a bit lackluster. It’s a good time for a beginner to get some practice, but for the rest of us, it might be worth waiting it out.
Into the middle of next week, it's more of the same. The swell direction holds from the SW, but the size stays in that head-high range and the quality is still being called into question. There’s a slight blip on the 13th where a bit more energy shows up for a morning, but it fades quickly. We're grinding through a pretty flat and average stretch here.
The real story is the tail end of the forecast. Looking out to the 21st, we’ve got a proper swell on the way. The models are showing a nice push from the SSW, and the energy numbers start climbing into the strong range. On the morning of the 21st, it’s looking like the best bet. Conditions are clean, and the swell is a solid 7.2ft with a long 15-second period. This is the standout. It’s a proper groundswell, and this reef is going to be handling it well. It’s not for the faint of heart though; that size is getting proper.
Then, things get really interesting. The 23rd and 24th bring a serious pulse of energy. We’re talking 9.8ft waves with even more power behind them, the energy readings are off the charts. This is big, powerful surf. This is for experts only. If you’re not comfortable in heavy, critical waves, sit this one out. It’s going to be a spectacle, but a dangerous one. The period stays long, which is good for the reef, but the size is the issue.
So here’s the deal. For the next week and a half, it’s a slow grind. Don't be surprised if the lineup is pretty empty because the waves just aren't that good. But hang in there. The surf is going to show up big time in the last few days of the forecast period. The 21st looks like the best balance of size and quality for experienced surfers. And for the very brave, the 23rd and 24th are going to be heavy.
Alright, I’ll catch you in the water.

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.
