Table - best surf conditions forecast for Ekas-Inside over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks. We’re dialling into one spot, a sheltered little reef called Ekas-Inside. It’s a beginner-friendly wave, and it’s fairly consistent, so there’s always a chance.
The water temp is sitting right around average for the time of year, so nothing wild there.
The outlook kicks off with a real tease. On Monday morning, July 13th, we’ve got a tiny 1ft SSW swell, but it’s packing some serious energy for its size (584) and the period is a very long 23 seconds. That’s proper groundswell. The wind is a gentle cross-offshore breeze, so it’ll be clean. It’s a small, glassy morning, but it’s a proper long-period swell, which can be a bit too straight for a beach break, but on a reef like this, it should offer up some nice, lined-up waves. The crowd factor is listed as “sometimes,” so you might have a few friends out, but nothing crazy.
Monday afternoon and Tuesday see the swell size jump up, reaching 6ft to 7ft by Tuesday morning, still from the SSW. The energy is ramping up big time (2327 to 2460), and the period is still long. But the wind picks up to a moderate breeze, and the forecast starts calling it “marginal.” It’s still clean, but it’s not the best quality. By Wednesday, July 15th, the swell holds around 7ft, and the energy is strong (2353), but the wind is a bit more on it, and the quality is still just okay. This is surfable, but it’s not the standout.
The real standout, the one you want to circle on your calendar, is Monday, July 20th. The morning session is looking promising. We’ve got a solid 7ft SSW swell, with a strong 17-second period and a massive energy reading of 2683. The wind is a moderate cross-offshore breeze. The catch is, at 7ft, this is getting into the territory where it’s more for the experienced crew, and the quality is still marked as marginal. It’s a big, powerful groundswell on a reef, so it could be a bit of a handful, but for those who can handle it, the potential is there.
After that, the swell stays around the 5ft to 7ft mark for the rest of the week, with the wind staying a consistent cross-offshore breeze. The energy readings drop off a bit, but it’s still a steady run of surf. The quality remains marginal, so it’s a “get what you can” kind of situation.
Into the second week, from July 25th, we see a bit of a pulse. Saturday the 25th afternoon brings another solid 7ft SSW swell with a 17-second period and a strong energy reading of 2556. The wind is a moderate cross-offshore. Again, it’s a groundswell, so expect some power and lulls between sets. The quality is still marginal, so it’s a wait-and-see, but the ingredients are there for a good wave if the tide lines up.
The following days, the swell slowly drops back down to the 4ft to 5ft range, with the wind staying light and cross-offshore. It’s clean, consistent, and small.
So, the best bet? That Monday morning, July 20th, is the biggest and most powerful window. It’s not for the faint of heart, but it’s the most energy we’ll see. For a more manageable option, the early morning of July 13th is a gem if you’re on a longboard or a funboard. The rest of the period is a steady, consistent run of surf, but nothing is screaming “perfect.” It’s a good run for a sheltered reef.
Rusty.

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.
