Aoshima Harbour Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what Aoshima Harbour has in store for us over the next couple of weeks.

Right off the bat, you’re gonna be sitting on your hands for a few days. The surf is tiny and ordinary today, nothing worth paddling out for. We’ve got a real mixed bag coming, with the first proper window of opportunity arriving next week.

The standout session by a mile is Tuesday, July 7th, first light. Aoshima Harbour wakes up to a clean 4ft swell from the ESE with a solid 14-second period (moderate energy at 540). But the real magic is the wind – glassy, dead calm. You couldn’t ask for cleaner conditions. The water temp is sitting at 79°, which is a bit colder than normal for this time of year, so a spring suit might be the call. This is the one to aim for.

Later that Tuesday, the swell bumps up to 5ft (927 energy), but the wind switches to a light cross-onshore, taking the shine off it. Still surfable, but not the glassy perfection of the morning.

Wednesday the 8th sees a jump in size – 7ft from the SE with a long 18-second period – but the wind is a cross-onshore breeze, making it choppy. For the experienced crew, it’s got power, but the quality is compromised.

From the afternoon of Wednesday the 8th right through to Saturday the 11th, things get properly wild. We’re looking at waves from 10ft to 13ft (energy readings between 4572 and a huge 9337). That’s a lot of water moving. The problem is, it’s too big for Aoshima Harbour. The wind is onshore or messy, and honestly, with that much power and onshore wind at a beach/jetty setup, this looks more like a kite surfer’s paradise than a paddle surfer’s. Leave it to the pros or the foil crew.

The second week is quieter, with smaller, cleaner windows. On Tuesday, July 14th morning you’ll find a glassy 3ft SSE swell (252 energy). It’s small, but clean. The same goes for the morning of Wednesday 15th – another 3ft ESE swell (231 energy) under glassy skies. Both of those are nice little grovel sessions.

Thursday the 16th morning brings a glassy 3ft from the east (289 energy) with zero wind. Perfect for a quiet paddle. Friday the 17th morning also offers clean 4ft from the east (300 energy) under glass.

But don’t get too excited about the last weekend. Saturday the 18th is a write-off with bumpy onshores, and then from Sunday the 19th into Monday the 20th, the ocean goes mental again – 10ft to 13ft (3444 to 5932 energy) from the east and ENE. Once again, way too big and messy for this spot. Keep the board in the car.

Overall, the real highlight is Tuesday morning the 7th for that glassy, 4ft ESE groundswell. The rest of the first week is either too small or too wild. The second week offers a few early-morning clean-up sessions, but nothing that will blow your socks off. It’s a typical summer pattern – pick your windows carefully.

Rusty.
