The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up at Akabane Long Beach. We’ve got a bit of a mixed bag over the next 16 days, so listen up.
Right off the bat, we’re in for a rough patch. The first few days are a write-off – Wednesday the 9th through to the morning of Friday the 11th is all onshore muck, with a stormy, choppy mess. The combined energy of the swells is strong, around 1216, but it’s a cross-on 12 mph wind and lumpy conditions, so it’s not worth paddling out for. The water temp is about average for this time of year, nothing to write home about.
The first real glimpse of hope comes on Friday afternoon, the 11th. The wind swings cross-offshore from the NNE at only 3 mph, and the ocean cleans right up. The swell is a small 3 ft from the south, with a period of 8 seconds. It’s not big, but it’s clean. The combined energy drops to 189 (weak), so it’s a gentle session for the longboard or a foamie. That’s the first stand-out window.
We then hit a dry spell. Saturday the 12th through to Monday morning the 14th is all cross-on breezes and tiny, messy waves. Nothing doing. Monday afternoon the 14th, though, we get a little relief. The wind shifts to WNW at 6 mph, making it cross-offshore and clean. The swell is a modest 4 ft from the southeast, with a 9-second period. Combined energy is 245 (moderate). It’s clean and surfable, but only just.
Tuesday the 15th and Wednesday the 16th are a mixed bag – some clean windows but mostly onshore junk. The best of that little stretch is Wednesday morning the 16th, with a light cross-offshore from the NW and clean 3 ft surf from the southeast.
Now, for the big news. The standout is definitely Sunday the 20th in the morning. The wind goes offshore from the north at just 3 mph, glassy conditions. The swell is a solid 8 ft from the ESE with a 7-second period. Combined energy is 555 (strong). That’s going to be a proper session – clean, punchy, and plenty of push. For the more experienced crew, this is your moment. The square 8 ft mark is getting close, so it’s not for beginners, but for the intermediate-to-expert crowd, it’s the pick of the window.
After that, we get a messy end to the period. Tuesday the 22nd morning has a clean window with 3 ft from the SSE and a 10-second period, combined energy 336 (moderate). But the real giant is Wednesday the 23rd and Thursday the 24th. The swell is predicted to be 10 ft to 12 ft from the south-southeast, with periods of 16-17 seconds – that’s a very long-period groundswell. The combined energy hits a massive 4016 to 7777, which is very strong. But the forecast says it’s likely too big for Akabane Long Beach, and the wind is cross-on. This setup looks more interesting for kite surfing than paddle surfing. Only the absolute experts should even consider it, and even then, it’s risky.
To wrap it up: the best on offer is the morning of Sunday the 20th, with clean offshore winds and solid 8 ft surf. The second best is the afternoon of Friday the 11th for a small, clean session. The rest of the window is mostly mediocre or too big and messy.
Stay safe out there, and don’t force it when it’s not on.
Rusty.
