The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next stretch. Straight up, it’s a long wait for anything worthwhile. We’ve got a solid two-week gap before we even see a glimmer of a wave worth paddling for.
The first few days are a write-off. We’re talking tiny, weak swell with poor surf conditions all the way through. From Wednesday the 29th of July right through to Monday the 10th of August, it’s just flat or too messy to bother. The swell is small, the periods are short, and the wind is mostly cross or cross-on. There’s a brief pulse around Sunday the 2nd of August where the combined swell energy hits 255 (moderate) and then 449 (moderate), but it’s all cross-on with a period around 15 to 16 seconds. That’s groundswell, but with the wind on it, it’s gonna be choppy and blown out. Not worth it.
The real story starts Tuesday the 4th of August. That morning, it’s glassy with a 10ft swell from the SE, period 17 seconds. The water temp is about average for the time of year. The combined energy is a strong 4574. That’s a proper groundswell. But here’s the catch – it’s too big for this setup. It’s an exposed beach, and with that much power, it’s gonna be a washing machine. Only for experts, and even then, it’s a beast. The wind is glassy, which is a huge positive, but the size is the issue.
Wednesday the 5th of August is the standout. The morning is looking clean with a light offshore wind from the N. The swell is 15ft from the SE, period 18 seconds. That’s a very long period groundswell. The combined energy is a massive 12980 (very strong). This is a serious, serious swell. For a beach break, that long period means it’s gonna break straight and fast, maybe a bit too much for a good shape. But if you’re a gun and you know the bank, that clean offshore wind could make for some rare, heavy barrels. It’s too big for anyone but experts.
After that, things get wild. Thursday the 6th of August sees 25ft to 31ft SE swell with near gale cross-shore winds. That’s not surfing, that’s survival. The energy numbers are off the charts (35216 and 79190). The rest of the week into the 10th is a mix of leftover big swell and strong onshore winds, making it a mess. By Wednesday the 12th of August, we’re back to small, short-period junk.
Finally, on Thursday the 13th of August, the morning brings a clean offshore wind from the NNW. The swell is only 5ft from the ESE, period 8 seconds. The combined energy is 342 (moderate). The conditions are clean, but the swell is small and short-period. It’s a glassy, fun-size wave for the longboard or a fish, but nothing to get excited about.
So, the one true standout is the morning of Wednesday the 5th of August. That’s your window. Massive, clean, offshore groundswell at Akabane Long Beach. It’s a beast, but if you’ve got the stones, it’s the only show in town.
Rusty.
