The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for our stretch of coast.
To be straight with you, the next week and a half is looking pretty grim. We’ve got a long stretch of tiny, weak waves and onshore junk. From now through to the 16th of August, you’re looking at nothing over 2 ft, mostly short-period slop, with a combined wave energy that barely hits double digits (10 to 26). It’s going to be a real struggle to find anything worth paddling out for.
There is a glimmer of hope on Monday the 17th. We see a pulse of chest-high swell push in, a clean 5 ft from the SSW. The wind is offshore from the WNW and the conditions are clean. The combined energy reads a solid 257 – that’s a proper kick of power after all this nothing. This is the standout of the entire window, and it’s still over a week away, so keep an eye on it. That 6-second period means it’s a wind swell, so it might be a little lumpy, but it’ll be a welcome change.
After that Monday morning window, it drops right back down into the doldrums. Tuesday the 18th sees a jump in period to 15 seconds, a real groundswell, but it’s only 0.7 ft to 1 ft – not enough to do anything with. The rest of the week stays small, mostly under 3 ft, with a few glassy mornings (like Saturday the 21st morning) that will be flat as a pancake. By the 23rd there’s a slight bump to 3 ft from the south, but it’s still just ordinary.
The very end of the outlook, around the 26th of August, shows a building trend with 4 ft to 4 ft from the ENE, but the wind is onshore and it’s chopped up. The energy is moderate (105-145), but the quality isn’t there for a surfing recommendation.
Honestly, the only real chance for a paddle this entire forecast is the morning of Monday the 17th. If you’re desperate, keep your eyes glued to that date. For now, the board stays in the car.
Rusty.
