Aoshima Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s on offer at Aoshima. This is a reef setup, and it’s pretty exposed to the swell. It’s fairly consistent, but this forecast is a bit of a mixed bag.

The outlook kicks off on Tuesday, July 7th, with morning glass. We’ve got a clean 4ft swell from the ESE with a 14-second period. The water’s sitting at 79°, which is a touch colder than you’d normally expect for this time of year – about 2° off. The energy is moderate (540). It’s surfable but the call is marginal. Through the afternoon, a risk of thunderstorms rolls in, and the swell bumps up to 5ft, still from the ESE, but the period jumps to a very long 16 seconds. That’s groundswell energy, and at this reef, it should wrap in nicely. The energy climbs to moderate-high (919).

Wednesday the 8th looks bigger. Morning sees a solid 7ft SE swell with a long 17-second period. The energy hits a strong 2423. This is getting into that zone where it’s more for experienced surfers. By the afternoon, it’s 8ft from the ESE, same long period, and the energy jumps to a very strong 3128. The wind holds offshore both sessions.

Thursday the 9th keeps pumping. Morning starts with 10ft from the SE, 16-second period, and a massive 3654 energy reading. That’s serious swell, definitely expert territory. The wind is still offshore, which will keep it clean. Thursday afternoon the swell holds at 10ft but the wind swings to a cross-onshore, putting a bit of chop on the face.

Friday the 10th is the absolute standout in this run. Morning delivers a solid 12ft swell from the SSE with a very long 17-second period. The energy is enormous at 7674. The wind is offshore. This is big, clean, powerful reef surf. The afternoon stays huge at 13ft and the energy goes through the roof at 8819. This is the best on offer, but it’s for experts only. If you’re not comfortable in serious size, stay on the beach.

Saturday the 11th sees the swell ease slightly but still big at 12ft in the morning and 10ft in the afternoon, both from the SSE with 16-second periods. Wind stays offshore. The energy is still strong.

Sunday the 12th, the swell starts to drop. We’re looking at 7ft in the morning and 6ft in the afternoon, both from the SSE with a 12-second period. The wind swings cross-onshore, and the energy drops to moderate (1200 and then 879). It’s a drop in quality.

Monday the 13th offers something worth looking at. The morning is glassy, with a 5ft SSE swell and an 11-second period. The energy is weak-moderate (464), but the glassy conditions will make for some clean, user-friendly waves. This is a good option for intermediate surfers.

After that, it trails off. Through Tuesday the 14th to Wednesday the 15th, we have small, weak, and generally poor or marginal conditions with cross-shore or cross-onshore winds. There’s a brief flash on Friday the 17th with a glassy morning showing 3ft from the E, but it’s small.

We then see a spike picking up again on Saturday the 18th. The afternoon brings a 10ft ESE swell with an 11-second period and a strong 2198 energy reading, and the wind is offshore. This is another big swell window, but it’s over a week out, so treat it as a promising possibility rather than a guarantee.

Sunday the 19th still has solid 8ft to 8ft swell from the E with offshore winds, holding energy in the strong range. Then from Monday the 20th onward, the wind builds and swings onshore, the swell fades, and conditions turn poor. By Wednesday the 22nd, we’ve got rain and a fresh breeze onshore, making it a write-off.

So to sum it up: the real standout is Friday, July 10th at Aoshima. That’s your big, clean, expert-only session with the offshore wind and massive SSE groundswell. For the average surfer, the glassy morning on Monday, July 13th is your best bet for a clean, manageable wave. Keep an eye on that late run around Saturday the 18th and Sunday the 19th if you can handle bigger surf.

Rusty.
