The Lowdown
Alright, mates, Rusty here. Let's have a proper look at the surf ahead for Akabane Long Beach.
The week kicks off with a bit of a tease. Thursday morning is looking clean, with that light offshore wind and a clean 5.2ft of SSE swell rolling in on an 8-second period. The water’s sitting at 81°, which is spot on average for this time of year, so no surprises there. It’s a fun, playful size, but the energy’s only moderate, so it’s not going to be a world-beater. It's a solid start, though. Later that day, things get a bit messy with a cross-onshore breeze, so the morning is your window.
Then we hit a flat, grim patch. From Friday through to Monday, it's pretty ordinary. We're looking at a run of poor conditions with cross-onshore winds, lumpy, choppy surf, and some funky, short-period swells. There are a few little pulses, but nothing that's going to get the heart racing. It's a good time to sort out your wax or fix a leash. This poor spell lasts until Tuesday.
Now, Tuesday the 15th is when we get a glimmer of hope. A light cross-offshore breeze and a clean 3.6ft of SE swell means the waves should be tidy. It’s not big, but it’s clean and that’s what counts. By Wednesday afternoon, things go glassy, with 3ft of swell, but it’s pretty ordinary, just surfable. The real standout of this long-range period, though, is Friday the 18th. The wind swings light offshore, and we see a proper groundswell starting to fill in. The period jumps to 18 seconds, and the energy kicks way up. That’s a sign of real quality, and the wave comment says to expect very good conditions. That’s the one to circle on the calendar.
But hold on. The ocean doesn't stop there. Saturday the 19th and Sunday the 20th see a massive pulse of long-period swell, with wave heights pushing 11.5ft to 16.4ft and energy readings going through the roof. This swell is too big for this break, simple as that. For the experienced chargers, it might be a spectacle, but for everyone else, it’s a washing machine. The wind is also onshore and choppy, so it’s not going to be clean. It'll be a sight to see, but not a place to be.
By Monday the 21st, it’s still huge, with a 23ft swell and glassy conditions, but again, way too big to ride here. This big pulse will have blown through by Tuesday, leaving behind some smaller, but wind-blown leftovers.
The last few days of the forecast period, from the 22nd to the 25th, drop right off. We’re back to small, weak swells and some nasty winds, including a period of near-gale force southerlies that will have things totally blown out. It all fades to nothing, to be honest.
So, to sum it up: the best bet for clean, fun waves is that Thursday morning window, and the one to get excited about is Friday the 18th, when that long-period groundswell fills in with clean conditions. Everything else is either flat, messy, or just too damn big. For a beach break, those big, long-period swells can also tend to close out, so that makes the call to sit them out even easier. This setup might look more interesting for the kite surfers once that onshore wind hits. Stay stoked.
