Aoshima Surf Forecast and Surf Report

G'day, Rusty here. Let's have a look at what Aoshima's got cookin' over the next couple of weeks.

We're starting off with a real beast of a swell on Tuesday the 25th, but the wind has got it all messed up. That big SE groundswell, pushing 13ft with a long 16-second period, has got some serious grunt behind it (combined energy 11077). But with a stiff NE wind onshore all morning, it's just gonna be a washing machine out there. The afternoon gets worse with stronger onshore winds, so we're not really looking at any clean surf here. It's a real shame, 'cause the water temp is sitting at a nice 84°, pretty average for this time of year.

Wednesday the 26th and Thursday the 27th are both pretty ordinary. We've got some decent sized swell left over, but it's coming with risk of thunderstorms and the wind is all over the place – cross-onshore and cross. The energy drops right off by Thursday afternoon to a weak 509, and we're left with short-period, messy waves. Not worth getting out of bed for, really.

There's a little glimmer on Friday morning the 28th. A cleaner window with light S wind, slightly offshore, and a small 4ft SE swell. The energy is weak (247), but for a beginner or someone who just wants a splash, the clean conditions make it a better bet. The rest of Friday, Saturday, and Sunday are small, with the swell dropping right down to 2ft and 2ft. Sunday morning the 30th is glassy, but there's barely any wave to ride (energy 119). Monday the 31st is flat and poor, so don't bother.

Then we hit a rough patch from the 1st of September through to the 4th. On Tuesday the 1st, the wind kicks up to 22 mph onshore, and by Wednesday the 2nd we've got a strong breeze (25-31 mph) tearing across a messy 7ft to 8ft ESE swell. That's a real kite-surfing setup, not for a paddle board. The energy stays moderate, but the conditions are blown right out. Thursday the 3rd is still howling.

Finally, some relief comes on Friday the 4th of September morning. Clean offshore winds from the SW, light at 6 mph, meet a 4ft SSE groundswell with an 11-second period. The energy is very weak (282), but the surf will be tidy and clean. It's consistent at Aoshima, and the offshore flow will groom it nicely. This is the standout option of the whole outlook – it's not big, but it's the cleanest we'll see. Saturday the 5th and Sunday the 6th look pretty average again, with onshore wind returning and short-period junk.

We get one last chance on Monday the 7th of September. A morning session with a light WNW cross-offshore breeze and a clean 4ft SSE swell (energy 417). It's a modest wave, but the conditions will be fun and pickable. After that, it's back to poor cross-onshore stuff for the rest of the period. The long-range window after the 7th isn't inspiring, so keep an eye on that Friday the 4th and Monday the 7th – they're your best bets. Aoshima is a reef break, so the longer period (11 seconds) on the 4th should give it a bit of shape. Crowds can show up here sometimes, so get in early.
