Aoshima Surf Forecast and Surf Report

G’day, Rusty here. Let’s cut through the chatter and get straight to it. This next stretch is a bit of a mixed bag, with a whole lot of nothing early on, then one giant, gnarly pulse of swell that’ll have the experts licking their lips but everyone else staying well clear. We’ve got a few days of waiting to do, so grab a coffee.

The forecast starts with a tease on Tuesday the 15th. First thing in the morning, there’s a clean 5ft of ESE groundswell at Aoshima. The wind is glassy, and the energy reading is a moderate 401. It’s a reef break, fairly consistent, but the options are limited. It looks surfable, but it’s not exactly a standout. That’s about as good as it gets for a while.

From there, it’s a slow slide into the doldrums. The rest of Tuesday and all of Wednesday and Thursday are junk – the wind swings cross-onshore, the swell drops off, and you’re just chasing whitecaps. The energy values drop into the low to mid hundreds, so there’s no push. You’re better off doing literally anything else. Friday the 18th sees the swell start to build again, but it’s doing so under a howling NE wind, bringing rain. The surf gets to 7.5ft and then 10ft, but it’s an onshore mess. The energy jumps up to a strong 1083, then 2243, but it’s unsurfable. Don’t even think about it.

Then things get interesting. Saturday the 19th rolls in with a big groundswell – 11.5ft early, pushing 13ft in the afternoon. The period is a very long 16 seconds, and the energy reading is a massive 7121. This is serious, powerful water. But the wind is cross-onshore and lumpy, so it’s going to be a battle. The forecast notes it as marginal. This is big, raw power, but it’s not clean.

Sunday the 20th is where it turns properly wild. We’re looking at 16ft of ESE swell with a 15-second period. The wind is a fresh cross-onshore breeze, and the energy is cranking at 9838. This is way beyond anything a normal surfer should be touching. You’d need to be elite and have a death wish.

Monday the 21st is the peak of this whole run. The swell is predicted to hit 20ft to 21ft, with a long 14-second period and energy readings over 20,000. That’s an absolutely colossal amount of water moving. The wind is strong and onshore, but the forecast notes that wind and tide are favorable. However, it also clearly states the swell is predicted to be too big for Aoshima. It’s an expert-only situation, and even then, it's likely closing out completely. This is not a day for the faint of heart. It’s something you watch from the cliffs, not paddle into.

After that monster, the week just gets messy. Tuesday the 22nd drops back down but it’s still a strong, cross-onshore 16ft. It’s all over the place. The rest of the week into the 28th is a tale of poor conditions – moderate to strong cross-onshore winds, lumpy seas, and a swell that’s all over the place. There are windows of smaller swell, but the wind never really cleans up. It’s not until the 28th and 29th that we see another big pulse, but again, it’s sloppy.

So, what’s the call? The only real standout in this entire window is that Monday the 21st event. It’s a true beast, with huge, long-period swell and maximum energy. But it’s not a surfer’s wave, it’s a big-wave charger’s dream. For the average punter, there’s nothing here that’s inviting. The break itself is only fairly consistent, and given the sheer size and onshore winds, this setup looks far more interesting for kite surfing than paddle surfing for most of the period. Save your energy and wait for the ocean to calm down.
