The Lowdown
Alright, Rusty here. Let's size this one up.
I've got to be honest, this is a tough outlook. The entire 16-day window, from September 8th through September 23rd, is a total washout. There's not a single session worth chasing. No standout days, no hidden gems – just a flat, wind-blown stretch of nothing at Walton Rocks (Power Plant).
The swell is basically missing in action. We're looking at tiny, weak energy for the whole run. The biggest combined energy reading touches 100 (moderate), but it's paired with a short period and crummy wind. Most days, it's well under 30 (weak energy). The swell is mostly from the east and northeast, which is the right direction, but the height is pathetic – 0.3m to 0.8m at best. That's not surfable.
The wind is the main problem. It's almost always cross-onshore or onshore, and when it's not, it's a moderate breeze stirring up chop. There are a few mornings, like September 11th and 23rd, where the wind goes light and clean, but the swell is completely flat. You'd have a glassy ocean with zero waves.
Water temp is 29°C, which is dead average for this time of year.
This is a very unusual dry spell for a spot that's normally very consistent. When it's like this, the setup is better for kite surfing than paddle surfing – the wind is strong enough, but the waves are just messy wind chop. Don't bother checking the forecast obsessively; this one is a real dud.
Rusty.
