The Lowdown
Alright folks, Rusty here. Let's have a look at what's in store for the region.
Look, I'm not gonna sugarcoat it – the next week and a half is a bit of a grind. The swell sticks around, sure, but the wind is a constant cross-off, and the surf quality is just hanging in the "marginal" zone. The real standout is buried way out there in the long-range, so we've got to be patient.
We start off with a bit of swell from the SW, but it's messy. The first real chance for a surf comes on Friday morning, July 17th, at Ekas-Inside. It's a sheltered reef, good for beginners, and the wind is a cross-off from the SE. The swell is 5ft from the SW with a very long period of 15 seconds, giving it some serious grunt with a combined energy of 1571 (moderate to strong). The water is a warm 81°, which is pretty average for this time of year. The trouble is, the forecast calls it "marginal," and I can see why – that long-period SW groundswell can be a bit tricky on a reef, and the wind isn't perfectly offshore. It's surfable, but not a standout.
The pattern stays locked in for the next few days. The swell ticks up a bit on Monday, July 20th, hitting 7ft from the SSW with a 17-second period and a beefy 2603 (strong) combined energy. That's a lot of water moving, but the wind is still onshore-ish. For a beginner spot, 7ft is getting a bit chunky, but more experienced surfers might find some fun. After that, the swell fades quickly through the rest of the week, dropping to 3ft by Friday, July 24th, with the combined energy falling to 740 (moderate). The wind stays fresh and cross-off, so it's just poor conditions.
Now, we get a little bump on the 26th, but it's a short-period SE windswell at 7ft with a period of only 8 seconds. That's short and steep, and for a reef, it's not going to be pretty. The combined energy is 1137 (moderate), but honestly, it looks more like a kite-surfing setup than a good paddle session.
The real story, the one that's got me looking forward, is way out on Friday, July 31st. We've got a solid 8ft swell from the SW, with a long period of 19 seconds. The combined energy is a massive 3920 (very strong). This is a proper groundswell. The wind is still a cross-off SE, but it's lighter in the morning at 12 mph. The break is a sheltered reef, which is perfect for this kind of long-period energy. The size is pushing into expert-only territory at over 8ft, actually it's 8ft, so it's a big, powerful wave for strong paddlers. The date is far off, so keep an eye on the models, but this is the one to circle. Saturday, August 1st, still has 7ft from the SW with a 17-second period, so if you miss Friday, the weekend might still have some leftovers.
