The Lowdown
Alright, Rusty here. Let's break down what Ekas-Inside has on offer.
So, for the next 16 days, it's a pretty inconsistent run. There's some decent SW groundswell here and there, but a lot of the time the conditions are just *okay* — clean lines but with that cross-offshore breeze, not the perfect glass you'd dream of. The water temperature is sitting right around 80°, which is dead average for the time of year, so you won't need much rubber.
The one true standout, and I mean the one that gets the heart pumping, is Friday morning, August 28th. You've got a solid 8ft SW swell, a very long period of 17 seconds, and a ton of energy behind it (4022). The wind is a clean cross-offshore from the SE at 9 mph. This is big, groundswell with a long period, so it might be a bit straight on a reef, but for the experienced guys on a setup like this, that's a proper session. Anything over 8ft is expert territory, so don't even think about it if you're not confident.
After that, the swell drops a bit but stays worth a paddle. Saturday morning the 29th is the next best bet with a 7ft SW swell at 15 seconds. The wind is cross-off again from the SSE, keeping things clean. Not the same power as Friday, but a solid option.
Then we get into a long stretch from the 30th of August through the first week of September. You're looking at lots of days with 5ft to 7ft surf, but always with a moderate cross-offshore wind. The combined swell energy is mostly in the moderate to moderate-strong range. A lot of these are called 'marginal' because of tide, so you'll have to pick your times wisely. It's not terrible, but it's not epic.
By the 5th and 6th of September, there's a little bump of 5ft SSW swell, but still with that moderate cross-off wind. Just okay again. Things really go flat around the 9th of September, dropping to 3ft on Wednesday afternoon and looking poor. The very end of the outlook, around the 10th and 11th, shows another SW groundswell building back to 6ft, so there might be something to look forward to, but it's a long way off. A patchy forecast, but that Friday the 28th is a proper, expert-level highlight.
Rusty.
