Aoshima Surf Forecast and Surf Report

G’day, Rusty here. Bit of a quiet start around Aoshima for the next few days, but there’s a serious pulse of swell building for the end of next week that’s got my attention.

We’re looking at a pretty flat and marginal run from Friday the 21st through Sunday the 23rd. Morning of Friday has a small 3ft SSE swell with light ENE winds, but it’s just not enough to get excited about. Saturday and Sunday are smaller again, with onshore or cross-onshore breezes keeping things messy. Nothing worth paddling out for.

Monday the 24th is where things start to change. By Monday afternoon there’s a 8ft ESE groundswell rolling in with a long 17-second period, but the wind is onshore at 12 mph from the ENE. The combined swell energy is pumping (3157), but it’s a bit raw. Not ideal, but you can see the engine starting.

Tuesday the 25th is pure chaos if you’re a paddler. We’re looking at 16ft to 20ft ESE swell with a fresh to strong cross-onshore breeze hitting 25 mph. That’s huge, unruly, and only for the madmen on jet skis. This setup looks far more appealing for kite surfing than paddle surfing. Combined energy is through the roof (18030). I’d sit this one out.

Wednesday the 26th sees the wind swing offshore from the WNW in the morning, but the swell is still a thumping 15ft with moderate rain and a strong breeze. It’s clean but still too big for most. Afternoon stays clean but the swell drops to 13ft.

Now here’s the standout: Thursday morning the 27th. Offshore wind from the WSW at just 9 mph, combined with a solid 8ft SE swell. That’s a big, powerful wave but within the realm of experienced surfers. Combined energy is 1413 – solid. The wind is offshore and gentle, so it’ll be clean with proper shape. This is the best session on offer. Just be aware that crowds are sometimes an issue here, and this is a reef break, so it’s more suited to those who know the lineup after the last few days of massive swell.

After Thursday the energy drops off quickly. Friday the 28th into the weekend sees small 4ft to 5ft SE swell with onshore winds and choppy conditions. Not worth chasing.

The following week has a few pulses of longer-period ESE groundswell, but consistent onshore winds keep the quality low until Wednesday the 3rd of September. That morning has a 13ft ESE swell with a very long 17-second period, gentle onshore winds, and combined energy of 9130. It’s a big, powerful groundswell that’ll be a bit straight for the beach, but on a reef like Aoshima it could offer some heavy, lined-up walls. That’s another promising day for experienced surfers only, though it’s further out and less certain.

All up, the standout is Thursday the 27th of August with clean offshore winds and a proper 8ft SE swell. Keep an eye on Wednesday the 3rd of September as a long-range possibility. The rest is mostly for the kites or the hardcore.

Rusty.
