The Lowdown
Alright, Rusty here. Let's have a look at what we've got.
Alright, so for this stretch, we're looking at a solid, extended run of surf at Ekas-Inside. It’s not going to be perfect every day, but there's a persistent pulse of SW groundswell that keeps things interesting for a long while. The water is sitting at a fairly normal 79°, so nothing weird there for this time of year.
We start on Tuesday the 25th of August with a clean 6 ft swell coming out of the SW, with a whopping 16-second period. That's proper groundswell energy. The wind is a cross-offshore from the SE at 19 mph, which will keep the surface tidy. It’s marked as marginal, but honestly, that's a decent wave for a beginner-friendly reef.
Wednesday the 26th stays similar, with 6 ft and 14-second period in the morning, and a slight drop to 5 ft in the afternoon. The wind backs off a touch to 12 mph, still cross-off. It's still clean.
Thursday the 27th sees the swell dip a little in size to 4 ft in the morning, but look at that period jumping to 20 seconds in the afternoon. That’s a very long period groundswell, which means heaps of energy for its size. These long-period SW swells will wrap in beautifully on this sheltered reef. It’ll be clean with a light 9 mph breeze.
Now, here’s where it gets interesting. Friday the 28th, the swell jumps to 8 ft with a 17-second period. That’s a solid, powerful wave. This is getting into the territory where beginners might find it a handful. For the experienced crew, this is going to be firing with that cross-off wind.
Saturday the 29th is the standout in the first week. The morning offers a 7 ft SW swell at 15 seconds, with a light 9 mph cross-off breeze. The forecast is calling for "expect very good surf conditions". This is the session to be in the water.
After Saturday, the swell drops back a bit for Sunday and Monday the 30th and 31st, sitting between 5 ft and 6 ft. The wind picks up to 16-19 mph, so it’ll be a bit bumpier but still clean. There's a long 19-second period in the mix on Monday morning, so there’s still quality juice in the water.
Heading into the second week, Tuesday the 1st of September delivers another solid push of 7 ft swell. The wind remains a constant cross-off.
The pulse continues through the week, with 7 ft on Wednesday the 2nd, then slowly tapering. The conditions stay consistent with that trusty SE cross-off wind. Friday the 4th of September sees the swell drop to 5 ft. The run is still surfable, but it’s winding down.
Then we get a nice spike again. On Sunday the 6th of September, we see 8 ft SSW swell building. And then the real kicker arrives on Wednesday the 9th of September, with a massive 10 ft SSW swell at an 18-second period. That is a big, powerful swell. This is strictly for the experts. The wind is a moderate 12 mph cross-off, so it won't be blown out, but 10 ft on a sheltered reef with that period is no joke.
The Verdict: The best on offer is hands down Saturday morning, the 29th of August. That 7 ft SW swell with light, clean cross-off winds and "very good" conditions is the session to circle. The long-range standout, if you're an experienced surfer and can wait, is Wednesday the 9th of September for that massive 10 ft groundswell, though it's a long way out so keep an eye on it. For the rest of the time, the constant, clean, cross-off winds mean you'll find a wave most days, even if it's not firing.
This is Rusty, signing off.
