Aoshima Harbour Surf Forecast and Surf Report

G’day, Rusty here. Right, let’s have a look at what’s on offer for Aoshima Harbour over the next couple of weeks. It’s a bit of a tough stretch, to be honest. The first week is mostly a write-off with onshore winds and messy conditions. There’s a glimmer of something better in the second week, but it comes with some serious size that’ll only suit the experienced crew. Let’s break it down.

We start off this Sunday, the 30th of August. The morning session is looking alright – small, clean, glassy waves around 3 ft from the SSE, with only moderate wave energy (152). It’s surfable, just very ordinary. By the afternoon the wind swings cross-shore and things get choppy and poor. Monday the 31st is similar: a tiny 1.6 ft glassy morning swell from the east with a nice 11-second period, so the shape might be half-decent, but it’s tiny. Energy is low (114). The afternoon goes cross-onshore and it’s pretty much a dud.

Tuesday the 1st of September through to Saturday the 5th is a real grind. The wind is almost constantly onshore or cross-onshore, often fresh, and the conditions are described as poor. The swell does build a bit – Tuesday and Wednesday see 4.6 ft to 6.2 ft from the SE with short 7-8 second periods, so it’s just lumpy and choppy. Energy levels climb into the low hundreds and then into the strong range (974 by Wednesday afternoon), but the quality is terrible. Thursday and Friday are more of the same: risk of thunderstorms, onshore wind, poor surf. Don’t bother.

Sunday the 6th is a real turning point, but not in a good way for most. The swell jumps to 9.8 ft from the east with a 10-second period, and the energy goes through the roof (1634 in the morning, 3383 in the afternoon). The problem is the wind is howling onshore at 15-18 mph, making it a complete mess. This is more of a kite-surfing setup than a paddler’s dream.

Monday the 7th of September, the swell stays big at 9.8 ft from the east, period 10 seconds, energy at 3375. The morning comment says wind and tide are favorable, but the swell is too big for this break. That’s only for the brave. Tuesday and Wednesday (8th and 9th) see the swell drop slowly from 7.9 ft to 5.9 ft, but still onshore wind and poor conditions. Not worth paddling out.

Thursday the 10th of September there’s a bit of hope. The wind eases to a light breeze, cross-onshore, with a 5.6 ft swell from the east, 10-second period, energy 951. It’s listed as marginal, but it’s the best we’ve seen in days. Friday the 11th brings a long-period groundswell from the SSE, 4.9-5.2 ft with a 14-15 second period, energy jumping to 1315-1797. The wind is light, mostly onshore or cross-onshore. The long period means the waves will have good power and shape, but at a beach setup like this it can break straight. Still, it’s a step up. The morning glass on Saturday the 12th is a tease: 9.8 ft from the SSE, 16-second period, glassy conditions, but again, too big for this spot. Sunday the 13th is even bigger – 16.4 ft from the south, 15-second period, glassy morning – only for experts and the insane.

Finally, on Monday the 14th of September, we get something worth getting out of bed for. The morning sees a clean, glassy 8.2 ft swell from the south, 10-second period, with strong energy (1976). The conditions are described as excellent for experienced surfers. The wind is almost nil from the NNW. This is the standout. There’ll be some crowd here as it’s sometimes busy, but the quality will be worth sharing it. If you can handle the size, this is your session.
