Aoshima Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming up for Aoshima.

Right now, the surf is pretty flat and ordinary. Monday the 6th has tiny 1ft swell from the ESE with a long 18-second period, but the energy is weak at 148, and conditions are just “surfable but very ordinary.” Not worth getting wet for.

Things change Tuesday morning the 7th. That’s your first real standout. The wind goes glassy, the swell bumps up to 4ft from the ESE, period 14 seconds, and the energy jumps to 540. It’s clean, glassy, and should be fun for a beginner to intermediate session at the reef. Water temp is 79°, which is about 2° cooler than normal for this time of year – noticeable but not crazy.

From Tuesday afternoon through the end of the week, the swell builds fast but the wind turns onshore and stays that way. Wednesday the 8th sees 8ft to 8ft SE swell with strong energy (3534 to 4438), but with ENE winds on it, the waves will be messy. Thursday and Friday get even bigger – 10ft to 12ft from the SE and SSE with energy readings over 5000 and up to 8621 – but the wind is onshore or cross-onshore, so it’s going to be a choppy, lumpy mess. These are expert-level sizes with poor conditions, so unless you’re chasing big, ugly waves, stay home.

Saturday the 11th and Sunday the 12th see the swell dropping back to 8ft to 6ft, but the wind stays cross-onshore and the energy levels are moderate. Nothing special.

Now, Tuesday the 14th morning is another standout. After a few days of mediocrity, the wind goes glassy again, and there’s a 10ft ESE swell with a short 10-second period and energy of 2115. That’s a solid, powerful wave – but it’s big. This one’s only for experienced surfers. The reef at Aoshima should handle the short period well, offering some punchy, clean waves for those with the skill.

Wednesday the 15th morning is also glassy with an 12ft E swell, but the period drops to 9 seconds. Still powerful, still big, still expert-only. The wind stays clean.

Towards the end of the forecast window, things settle. Friday the 17th morning has glassy 5ft E swell, and Saturday the 18th morning has glassy 6ft E swell – both with 8-second period and moderate energy. These are more manageable sizes, clean conditions, and should offer fun waves for a broader range of surfers. Sunday the 19th and Monday the 20th mornings also look clean and glassy with 7ft to 7ft E swell – good, consistent options.

Avoid the 21st – fresh NNE winds at 30-35 km/h and lumpy conditions make it a write-off.

Overall, the best sessions are Tuesday the 7th morning and Tuesday the 14th morning. The first is a smaller, glassy, fun day for all levels. The second is a bigger, cleaner, expert-only session. The later mornings around the 17th to 20th are also solid, clean options.

This is Rusty, signing off.
