The Lowdown
Alright folks, Rusty here, with a look at what Southport Main Beach has got cookin’ over the next couple of weeks. I’ll be straight with ya – it ain’t lookin’ pretty for a while.
We’ve got a long, quiet stretch ahead. For the first week, from Sunday the 13th through to Saturday the 19th, the surf is just not cooperating. The combined energy is weak, barely hitting 90 at best, and the wind is a constant problem – mostly cross or cross-onshore, keeping things bumpy and messy. The water temp is sitting at 70°, which is pretty much what you’d expect for this time of year, so nothin’ special there. You’d be lyin’ if you said there was any real quality to chase. The only glimmer comes on the morning of Saturday the 19th, where the conditions go “marginal” with some cleaner, light cross-shore breezes and a 4ft swell from the ESE at 11 seconds. That’s a long period for a beach break, so it might be a bit straight and sectiony, but it’s the closest we get to a wave in that whole first week.
After that, it gets even quieter. From midday Saturday the 19th all the way through to the end of the period on Monday the 28th, there’s not a single day worth getting wet for. The swell drops right off, with heights barely hitting 3ft and periods sitting short. The wind is all over the place – strong breezes, onshores, and even a near gale on the 21st. The energy is just pathetic, all under 100 and most of it under 50. Plenty of wind but no real push behind it.
So there you have it. We’ve got a near two-week gap of poor to non-existent surf. The only faint heartbeat is that Saturday the 19th morning window, but with the long period and a beach break like Southport, you’ll have to work for any nuggets. Hang in there, it’ll come back.
Rusty.
