The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up in our patch. I’ll be straight with you – the outlook for the next couple of weeks is a bit of a slow burn.
We’re starting off on Thursday the 13th, and honestly, there’s no surf to speak of right now. The energy coming in is tiny, with a combined swell energy of only 5, which is about as weak as it gets – a pathetic 2ft of slop from the NW. That’s not going to get you out of bed. We’ve got a bit of a gap here. It’s pretty much a write-off for a solid week. There will be tiny scraps of swell here and there, but nothing that I’d call a surfable recommendation until the following week.
It’s not until Friday the 21st of August that we finally see a pulse of energy roll in. This is for Gantheaume Point (Broome), a classic beach and point setup. We’ve got some long-period groundswell arriving from the west, with a period hitting 19 seconds on the Friday afternoon – that’s some real energy for the offshore banks. The combined swell energy tops out at a moderate 13, which is still modest but a huge step up. The swell height itself is only 0.3ft, but the period is what matters for points like this. The wind is swinging offshore from the SW at 16 mph, keeping things clean. This is a rare breaking spot, so when it lines up, it’s a special thing for those who know it.
Even bigger in terms of period is the swell on Saturday morning the 22nd. Still only 0.3ft of west swell, but with a period of 16 seconds and clean cross-offshore winds from the ESE at 12 mph. The water temp is sitting at 73°, which is a bit colder than normal by about 2°, so you might want a light spring suit if you’re sensitive. This spot is rarely breaking, so to have two days in a row of clean, long-period groundswell is a genuine standout for the hardcore local.
That’s your window. The standouts are definitely the Friday the 21st afternoon and the Saturday the 22nd morning. After that, we trickle back to tiny waves and onshore breezes. If you can get out there on those two days, you’ll be in for some clean, glassy lines on a point that doesn’t fire often. For the rest of the period, it’s a waiting game.
