The Lowdown
G’day, it’s Rusty here. Let’s be straight with you—this stretch of coast is looking flat and pretty lifeless for the next couple of weeks. I’ve been staring at the charts and there’s just nothing pushing in. We’re talking a complete blank run for the entire 16-day window, which is a real bummer if you’re hanging for a wave.
There’s a tiny pulse of life early on, but it’s barely a ripple. On the morning of the 16th, we might see a touch of swell around 2ft from the southwest, with a weak period of 5 seconds. The combined energy is a measly 11, which is just weak. The wind is light offshore, so if you’re absolutely desperate for a knee-high dribble, you might get a clean one. But honestly, that’s a “maybe” wave for the die-hards only.
The water is sitting at 83° and that’s a whopping 4° warmer than normal for this time of year—that’s seriously unusual, like bathwater out there. It’s a nice thought if you’re having a swim, but it doesn’t help the surf.
There’s a bit of a southwest bump showing on the 23rd, but again, we’re talking 0.3ft. That’s not even a wave. It’s a ripple. The wind is light offshore that morning, which would keep things glassy, but there’s nothing to ride. This spot is a sheltered beach and point break that rarely breaks, and that’s exactly what’s happening. The swell direction is all wrong for this corner, coming from the southwest when it needs something from the southeast.
If you’re a beginner, you’re not missing out on anything because there’s no size to worry about. Safe to say, the kites are going to be the only things moving out there if the breeze picks up, because the surfboard’s staying on the rack.
It’s a tough outlook, but this spot can be fickle. Forecasts change, and it won’t stay this poor forever. Keep an eye on it, but don’t book the day off work just yet.
Rusty.
