Aoshima Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Aoshima over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a slow period. The first real surf worth paddling out for doesn’t show up until Monday the 13th of July, and even then it’s not exactly pumping. The overall pattern is small, clean, and pretty weak. The standout window is actually right at the start, with Monday afternoon offering the best combo of size and conditions.

Monday the 13th afternoon at Aoshima, we’ve got a 4ft swell from the SSE with a 10-second period. The water is sitting at 80°, which is a bit colder than normal for this time of year – about two and a half degrees off the average. The wind is light from the south at 6 mph, blowing cross-offshore, so the waves will be clean. It’s a reef break, exposed to the swell, and the energy is moderate (358). This is your best bet for the whole outlook, but don’t expect a crowd – it’s only *sometimes* busy here.

Tuesday the 14th morning drops off a bit. We’re down to 3ft from the south, period 9 seconds. The wind shifts to a light offshore from the west at 3 mph, so it’s glassy. The energy is moderate (139). It’s surfable, but ordinary. Tuesday afternoon gets even smaller and the wind turns cross-on from the east – not ideal.

Wednesday the 15th and Thursday the 16th are tiny. Wednesday morning has 2ft from the south with a light offshore, but the energy is weak (84). Thursday is even smaller, 1ft, with a light offshore from the west. The energy is down to 54. You’re basically looking at knee-high dribble. Clean, but barely rideable.

Friday the 17th through to Sunday the 19th, the swell stays tiny – around 2ft to 2ft from the east. The wind is glassy or light, which is a positive, but the energy is still weak (under 100). It’s clean, but you’ll be scratching for a wave.

The next notable bump comes on Thursday the 23rd of July. We see a bit more energy in the water – 3ft from the east at 10 seconds, with moderate energy (190). The wind is light from the south, cross-offshore, so it’s clean. Still not big, but it’s a step up from the flat spell. Friday the 24th and Saturday the 25th are similar, with 3ft and 2ft, still clean in the mornings.

Now, look ahead to Monday the 27th of July. The swell jumps to 6ft from the SE at 12 seconds – that’s a long period groundswell. The energy is strong (1041). But here’s the catch: the wind is cross-on from the NNE at 9 mph, and then onshore from the ENE in the afternoon. It’s gonna be lumpy and choppy. This is a case where the size is there, but the quality is poor. For a reef break, that long period groundswell could make it a bit weird – might be better for a point, but we’ve only got Aoshima. The afternoon on the 27th is a write-off.

Tuesday the 28th is still 5ft from the SE, but the wind is cross-on and choppy, so it’s not worth the paddle.

Overall, your best session is Monday the 13th afternoon. The rest of the 16 days is a mix of small clean waves and a few bigger, wind-affected days. There’s a big gap of nothing special from the 14th until the 23rd, so don’t plan a trip around it. Forecasts can change, but right now, it’s a pick-and-choose kinda window.

Stay stoked,
Rusty
