The Lowdown
Alright, this is Rusty comin' at you from the beach. Let's have a look at what the next couple of weeks are serving up for Akabane Long Beach.
We've got a bit of a slow start, but don't let that fool you. The real story here is a solid pulse of swell that arrives later in the week, bringing some serious grunt and some excellent conditions for those who know what they're doing. The water temp is sittin' about average for this time of year, so nothin' wild there.
We start off pretty average, to be honest. Wednesday the 16th is a write-off with small, poor surf and onshore winds, not worth paddling out for. Thursday the 17th morning shows some improvement with a glassy 4ft swell from the ESE, but it's a short period of 7 seconds, so it's a bit weak and won't have much push. Still, for a sneak out, you might find a clean little ripple.
Friday the 18th is still pretty ordinary. The swell bumps up to 7ft on the morning from the east, but it's cross-onshore, so it's gonna be bumpy and hard to enjoy. The wave energy is only moderate (998), nothin' to write home about.
Now, here's where things get interesting. Saturday the 19th is your first standout. The morning brings a clean 8ft swell from the SE with a lovely 13-second period – classic groundswell. The wind is offshore from the NNW, and it’s glassy by the afternoon. This is clean, powerful surf but at 8ft it's in the "experienced surfers only" zone. The wave energy is strong (2312), and this thing has some push. If you know what you're doing, this is a proper session.
Sunday the 20th is the pick of the bunch for me. The swell holds at 8ft from the SE, but the period stretches to 12 seconds and the wind goes proper offshore from the NNW. By the afternoon, you've got a steady offshore breeze and the wave energy is very strong (3715). The waves will be well-shaped, clean, and powerful. This is the best on offer for the experienced crew.
Monday the 21st is a big warning. A monster 16ft swell from the SSE with a very long period of 15 seconds rolls in. This is not a paddling day for almost anyone. The wind is howling offshore, so it'll be clean, but it's too big. This kind of energy (10553) is for jetskis and tow-ins, not your regular paddle session. Steer well clear unless you're a pro.
Then it all drops off a cliff. From Tuesday the 22nd right through to the end of the month and into October, the surf goes flat and tiny. The swell drops below 3ft, winds are messy, and the period is short. There is a little blip on Sunday the 27th with a 8ft ESE swell, but the onshore wind and short period (8 seconds) make it a mess. It's a massive gap of nothing for over a week. The only thing worth mentioning at the very end is a tiny 1.0ft swell on October 1st with a very long 17-second period, but that's a whisper, not a wave.
So, bottom line: If you've got the skills, get out there on Saturday the 19th and Sunday the 20th. That's your window. The rest of the outlook is a fishing trip, not a surf mission.
Rusty.
