The Lowdown
Alright, Rusty here, let’s talk about what’s coming up at Peak Rock.
Mate, it has been a rough start. For the first few days we’re looking at a real messy ocean – strong cross-onshore winds and a big, powerful, chaotic swell. Honestly, not worth paddling out. The combined energy is huge (7431 to 13855), but it’s just a washing machine. Water temp is sitting at 56.3°, which is pretty normal for this time of year.
The first real glimmer of hope comes on Friday morning, September 11th. The wind drops to a dead calm – glassy conditions. We’ve got a 6.9ft SW groundswell with a long 15-second period. The combined energy is strong (2085), but it’s only for experienced surfers. Saturday morning, September 12th, is also looking clean with a light cross-offshore breeze and a 7.2ft SW swell. Not huge, but rideable and tidy. Sunday the 13th brings proper offshore winds from the NNW, around 15-19 mph, dropping the swell a bit to 5.2ft, but it’ll be clean. Still, nothing I’d call a standout.
Now, the real standout is Wednesday morning, September 16th. This is the one to circle. We get a 7.9ft SW groundswell with a long 16-second period, and the wind is a light offshore from the NNW. Combined energy is very strong at 4092. This is going to be excellent for experienced surfers – clean, powerful lines. Great chance of a proper session before the crowds (which are possible here) wake up.
Another good window is Saturday morning, September 19th. Glassy again, with a 7.9ft SW swell. The combined energy is still solid at 1886. Perfect conditions for those who can handle it, as it’s still in the expert range.
Looking further out, the big one to keep an eye on is Wednesday, September 23rd. The models are showing a real spike with a 13.1ft SW groundswell and a very long 19-second period. The combined energy is enormous (11906). This is a massive, long-period groundswell. At a reef break, expect some proper, powerful, organized lines. It’ll be a sight to see. Conditions are uncertain, but the potential is huge. Keep an eye on the wind as it gets closer.
