The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking.
Well, I’ll be honest with you, the next week or so is looking pretty grim. We’ve got a stretch from today, the 12th, all the way through to the morning of the 15th that’s just not worth getting wet for. The wind is messy and the waves are small and weak, with combined energy barely breaking the 200 mark. It’s a write-off.
There’s a tiny flicker of hope on the afternoon of the 15th. Akabane Long Beach goes glassy, with a clean 3ft swell rolling in from the SE. The energy picks up a bit to 210, and it’s surfable, but it’s not going to set the world on fire. Wednesday the 16th is clean but ordinary, and Thursday morning the 17th is glassy again but the swell is still only 4ft. Honestly, you’re just scratching for scraps.
Now, if you can wait, Friday morning the 18th is where things finally get interesting. That’s the standout of the first week. We’ve got a solid 6ft swell from the east (587 combined energy), it’s glassy, and the conditions look very good. That is your window.
But hold onto your board, because the real juice shows up on Saturday morning the 19th of September. The models are throwing a huge 13ft SE swell at us with a very long 14-second period. The energy reading is a massive 9990. That is serious, ground-swell power. However, for Akabane Long Beach, that is just too big. It’s an expert-only scenario, and even then, with that period, it might be breaking a bit straight for the beach. The wind is a moderate cross-shore, which won’t help. That morning is for the brave and the experienced, and the brave with good insurance. Sunday the 20th afternoon cleans up nicely with a 8ft swell from the SE and light cross-offshore wind – that’s the best wave quality of the whole run for the average experienced surfer.
The following week starts to fade. The swell on the 21st is still big and messy, and by Wednesday the 23rd the stormy winds return, shutting it all down. We’re left with clean but tiny surf by the 27th.
So, to sum it up: don’t bother until the 18th morning. That’s your first real chance. Then look hard at the afternoon of the 20th for the cleanest, biggest, most powerful swell that’s still manageable.
Water temp is sitting at a warm 80°, which is bang on average for this time of year. No surprises there.
Rusty.
