The Lowdown
Righto, let’s have a look at what we’ve got here. We’re talking about Akabane Long Beach – that’s the only spot on the cards, so it’s all eyes on that stretch of sand and sea.
Straight up, the first week and a bit is a write-off. From Saturday the 12th through to Thursday the 17th, it’s pretty grim. Swell is tiny, wind is junk – mostly cross or onshore, and the water’s a mess. The combined energy is weak, hanging between 106 and 221 – hardly enough to push a ripple through. There’s a couple of “marginal” calls in there on the 15th but honestly, not worth paddling out for. This stretch is a solid six-day gap with nothing to recommend.
But then, hold onto your board. Friday the 18th is where the whole outlook flips. That morning, we get a proper pulse of groundswell – 5ft from the SSE, with a very long period of 18 seconds. Wind is glassy, dead calm from the north, so the surface will be like a mirror. The combined energy jumps to 1434 (moderate to strong), and the conditions are rated excellent for experienced surfers. This is the standout of the whole run – a real window of quality, long, clean lines. That kind of period suits point breaks and reefs better than a beach, but if the banks are right, it could be magic. Crowds are “often” here, so expect company.
The afternoon of the 18th gets a bit lumpy with a cross-on breeze, and the swell drops off in quality. Still some size at 7ft, but it’s messy.
Saturday the 19th – big numbers, but a problem. Swell hits 12ft from the SE, with combined energy roaring up to 5227 (very strong). That’s too much for this break – it’s flagged as too big. The wind is a fresh cross-shore, and it’s just not going to be surfable for most. Leave this one alone unless you’re a charger with a big-wave gun and nerves of steel.
Sunday the 20th through to Wednesday the 23rd is a mixed bag of lumpy, windy, onshore slop. Swell stays between 6ft and 16ft, but wind is consistently fresh to near-gale, and the water’s blown out. Not your friend.
Wednesday the 23rd afternoon has a clean moment – cross-off wind from the WNW, but the swell is a massive 18ft (energy 9423) – way too big and only for the most experienced. The Thursday morning the 24th is a real bright spot: 8ft SSE groundswell at 16 seconds, with a moderate offshore from the NNW. Clean conditions, excellent for experienced surfers. That’s your second standout.
From there, the 25th and 26th just see the swell ballooning again – 10ft to 16ft, too big for this break, even if the wind is favourable. The energy readings are off the charts (up to 12695). This is more of a spectacle than a surf session.
So bottom line: Friday morning the 18th is the best on offer – glassy, long-period SSE groundswell at 5ft. Thursday morning the 24th is your second pick – clean offshore, solid 8ft groundswell. Everything else is either flat, messy, or way too big.
