The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Ekas-Inside.
It’s a bit of a mixed bag this fortnight. The wave energy is all over the place, and the wind is stuck in a cross-off pattern from the southeast, which is not ideal for that glassy perfection we all crave. The main standouts are around the middle of the period, and again right at the very end, but a lot of the time it’s just marginal.
We start off on Friday 17th July with a solid 5 ft to 5 ft SW swell, but the 19 mph breeze on the afternoon scan makes it feel a bit choppy. The combined energy is strong at 1571 to 1633, but the conditions are just not there for a top-notch session. The water temp is about par for the course, nothing wild.
The weekend is more of the same – Saturday 18th and Sunday 19th hold 4 ft to 5 ft SW swell, but the wind is a constant 16 to 19 mph from the SE. The scores are low, and Sunday afternoon actually turns poor. The energy drops from 1124 to 989, so it’s a bit of a grind.
Now, Monday 20th July is where my eyes light up a bit. The swell jumps to 6 ft to 7 ft, coming from the SSW with a period of 16 to 17 seconds. That’s a proper long-period groundswell. The combined energy is pumping at 2419 to 2204. The wind is still 16 mph, but it’s cross-off, so it’s not horrible. If you can handle a bit of a side breeze, the morning will be the cleaner window. This is a decent chance for a surfer who knows the reef.
Tuesday 21st and Wednesday 22nd fade a bit, with the swell dropping to 4 ft to 6 ft, and the energy falling to below 700 by Wednesday afternoon. That’s weak. The remaining days up to the 30th are mostly poor or marginal, with a few brief moments of 4 ft to 4 ft swell, but nothing to get excited about. The energy is mostly in the hundreds, which is weak.
Look, the real gem is hiding at the very end of the forecast. On Friday 31st July, we see a new pulse arrive: 4 ft SW swell at 18 seconds in the morning, building to 5 ft SW at a massive 22 seconds in the afternoon. The combined energy rockets to 2578 and then 3523. That’s a serious, very long-period groundswell! The wind is still 12 to 19 mph, but early morning will be your best bet. This is the standout for the whole run. Then, on Saturday 1st August, we get 7 ft SW at 20 seconds, with energy at 4785. That’s a big swell for Ekas-Inside. It’s a solid 7 ft, which is getting into expert territory, and the period is very long, so it’ll be fat and powerful on the reef. Be ready for that.
The biggest bummer is the wind. It never goes offshore or light, just a constant cross-off breeze. That keeps the quality from being truly epic. The best day is probably the 31st of July, with that long-period SW groundswell, if you can get out early before the wind ramps up.
Rusty out.
