The Lowdown
IMPERIAL
Alright mate, Rusty here. Let’s have a look at Injidup Carpark. This reef setup is a bit of a fickle one, doesn’t break all that often, so when it lines up, it’s a special place. The water’s sitting at 66°, a touch warmer than normal for this time of year, which is a nice bonus.
The forecast through the next week is a bit of a mixed bag. We’ve got a serious pulse of swell coming in, but it’s going to take a while to get clean. That first Tuesday afternoon, the 18th, it’s big – 4.5m of WSW groundswell with a very long period of 16 seconds, and the energy is pumping (8820). But the wind is howling from the NW at 19 mph, right onshore, so it’s a mess. Forget it.
Wednesday the 19th and Thursday the 20th aren’t much better. The swell stays big, between 13 and 15 feet, but it’s cross-on or just cross-shore with a chop. The wave energy is still massive (up to 9739 on Wednesday afternoon), but the quality is poor. You’d be a glutton for punishment.
Now, hold on. Friday morning, the 21st of August, is where it gets interesting. The swell drops to a cleaner 11 feet from the WSW, with a period of 14 seconds. The energy is still strong (5010), but the real winner is the wind: a light 3 mph offshore from the east. That’s glassy, clean conditions. The comment says “excellent for experienced surfers,” and that’s spot on. At 11 feet, this is expert territory, but for those who can handle it, it’ll be a standout. Keep in mind it’s an inconsistent break, so be patient, and crowds are possible.
Saturday morning, the 22nd, also looks promising with a 10-foot SW swell, a 16-second period, and a clean cross-off breeze. The energy is still hefty (3953). A solid option for the experienced crew.
The week after that turns messy again with strong winds and onshore slop, especially around the 25th with 28 mph winds. There’s a gap in quality, but then we get a nice run from Thursday the 27th into early September. The standout looks to be the morning of the 2nd of September: 11 feet of WSW groundswell with a 15-second period, a clean cross-off breeze, and the energy is still strong (4893). The comment calls it “excellent for experienced surfers.” That’s a long way out, so keep an eye on it, but it has real promise.
For the best of the best, I’d lock in Friday morning, the 21st of August, with that offshore wind and solid groundswell, and keep an eye on the 2nd of September as a promising long-range target.
Rusty.
