Aoshima Harbour Surf Forecast and Surf Report

G’day, Rusty here. Let’s have a look at what’s coming up for Aoshima Harbour.

We’re kicking off with a bit of a slow start. Thursday the 27th has some swell around, but the threat of thunderstorms and a cross-off wind make it feel more like a mission than a fun session. The surf is there, around 7ft from the SSE, but the energy is moderate (636) and the vibe is just “marginal.” Not the kind of day you’d rush out for.

Friday the 28th morning looks a little more promising with a cleaner 5ft swell from the SSE, light cross-off wind, and the combined energy dropping to 308. It’s surfable, but nothing to write home about. The afternoon turns ugly with a cross-shore breeze and a messy 4ft wave.

We hit a real dry patch from Saturday the 29th through to Thursday the 3rd of September. The swell is small, often under 3ft, and winds are mostly onshore or cross-shore, with many afternoons getting chopped up. The water temperature is about average for this time of year – nothing unusual there.

Now, Friday the 4th of September morning is a standout. We’ve got a solid 12ft swell from the SSE, clean as a whistle with a cross-off wind, and the combined energy is pumping at 5638. That’s a serious amount of power. But, and this is a big but, that size is too much for the harbour setup. Only for expert surfers, and even then, it’s going to be a beast. The period is 12 seconds, so it’s a proper groundswell, but at a beach/jetty break like this, it might just close out. Still, if you’re experienced and looking for a challenge, that’s your window.

The following week has a few more moments. Wednesday the 9th of September morning is glassy, 6ft from the east, with zero wind and a combined energy of 1104. That’s clean, solid surf – excellent for experienced surfers. Thursday the 10th morning is also glassy, 8ft from the east, and energy hits 1547. That’s a big, clean swell, but again, over 8ft means it’s expert territory. The afternoon gets messy with a cross-shore breeze and a 10ft wave that’s too big for most.

So, the best bets are that Friday the 4th morning for the adrenaline junkies, and those glassy mornings on the 9th and 10th for cleaner, more manageable waves. Crowds are possible at Aoshima Harbour, so keep your eyes peeled.

If you’re not into that size, the setup might look more interesting for kite surfing than paddle surfing on those bigger, windier days.

Rusty.
