The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the only spot that's showing any action.
The entire 16-day window is a tale of one break: Akabane Long Beach. There's a bit of a gap right at the start, but we kick things off on Wednesday, August 26th. Now, don't get too excited, because this is a mixed bag.
We start with a solid pulse on Wednesday morning. A 6ft south swell with an 11-second period is pumping in, and the combined energy is a solid 829 (moderate). The wind is a light 6 mph from the west, making it a cross-offshore breeze. The report says "expect very good surf conditions," and with that wind, it's looking clean. This is the standout of the whole run. The swell direction (S) is a tick off the optimum (SSE) but it's close enough to work. The break is very consistent, so you won't be waiting around. Keep in mind, at 6ft, it's pushing into intermediate territory, but it's not out of reach for a keen beginner on a good day. The water temp is about average for this time of year, nothing weird to report.
That Wednesday afternoon, though, it all goes pear-shaped. The wind swings to the SSW at 16 mph, turning it onshore and choppy. The swell drops a touch, but the quality is gone. The report calls it "poor surf conditions."
Thursday, August 27th, is a write-off. The morning is a 3ft SSE swell with a light cross-shore, but the report says it's "marginal." The afternoon is a bit bigger at 5ft, but the wind is onshore again. Not worth paddling out for.
Friday, August 28th, brings a glimmer of hope. We get a morning of clean 3ft south swell with an 8-second period and a light offshore breeze from the NNW. It's small, but clean. The wind is the key here. The report says "expect good surf conditions," so a fun little wave for the log or a mid-length.
Saturday, August 29th, starts with a tiny 2ft south swell and glassy conditions. It's small, but if you're desperate, it's rideable. The energy is weak (115). The afternoon is a complete dud.
Sunday, August 30th, is another day of tiny, weak swell. The morning is 3ft with a 6-second period and glassy, but the energy is only 98. It's a lake.
From Monday, August 31st, all the way through to Thursday, September 10th, the pattern is blown out. The wind is hammering from the east and southeast, consistently 16 to 28 mph. The swell gets huge – we're talking 10ft, 12ft, even 20ft on September 8th – but it's all messy, onshore, and dangerous. The combined energy hits 5496 and even 10041 (very strong) on those days, which is a massive amount of power. But with the wind and the onshore direction, it's unsurfable. For a stretch of over a week, it's just a washing machine. At 10ft and over 8ft, it's strictly for experts anyway, but with the wind, it's a no-go for anyone.
The energy stays high, but the wind ruins it. The only real hope was that Wednesday morning, August 26th. If you missed that, you're waiting for a change in the wind pattern, which might not come until the very end of the forecast. For now, Akabane Long Beach is a kite-surfing show, not a paddle-surfing spot.
Rusty.
