Aoshima Harbour Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what’s in the water for the next couple weeks.

First few days are a bust. Tuesday the 8th is ugly with a fresh cross-onshore wind and lumpy, poor surf. Wednesday morning the 9th is a different story, though. Glassy conditions at Aoshima Harbour with a 5ft swell from the ESE and a period of 8 seconds. The combined energy is moderate at 320, and it’s clean as a mirror. This is a small, fun window for an intermediate surfer, but it’s not powerful. Water temp is about average for this time of year, so it’s comfortable.

After that, it’s flat and messy. Thursday and Friday the 10th and 11th have cross-onshore winds or light cross-shore chop, with the swell dropping right off. Saturday morning the 12th has a glassy surface but only a tiny 2ft, 14-second period groundswell from the east. That long period will make it straight and weak at a beach/jetty, so it’s barely surfable. Sunday the 13th and Monday the 14th are messy with onshore winds and poor conditions.

There’s a pulse on Tuesday the 15th with 5ft from the ESE, but the wind is cross-shore and conditions are marginal. Not a standout.

Look ahead to Saturday the 19th. The afternoon glass-off is where it’s at – 4ft from the east, 8 seconds, and glassy. The combined energy is 387, so it’s a moderate little wave. For a beach/jetty, it’ll be fun and clean, but crowds are possible.

The real headline is Monday the 21st and Tuesday the 22nd. We’ve got a massive swell coming. On Monday morning, we’re seeing 7ft from the ESE with a very long period of 16 seconds. The combined energy is a huge 2434 – that’s powerful. By Tuesday morning the 22nd, it’s a solid 10ft with the same direction and period, and the energy is off the charts at 5060. This is for experts only – way too big for beginners. The wind is light and cross-onshore, and the tide is favorable, but the wave comment says it’s likely too big for this break. Potential for some serious cleanup sets, but you’ll need to know what you’re doing. This is the standout, but it’s a long-range call, so keep an eye on it.

So, the best bet is the glassy Wednesday morning the 9th for a small, clean session, and the big, expert-only swell around the 21st and 22nd. There’s a gap of poor to marginal surf from the 10th through the 18th, so don’t expect much in between.

Rusty.
