The Lowdown
G'day, Rusty here, checkin' in from the local surf scene. We've got a 16-day window that's a bit of a slow burn. The first solid recommendation doesn't appear until July 23rd, so we've got a week of small, ordinary conditions to get through first. The standout action is right at the tail end of the outlook, and it's a bit of a ripper.
The first real chance to get wet with something decent is on July 23rd. Aoshima is the spot. It's an exposed reef, so it needs the right swell. We've got a clean 3 ft easterly swell pushing in with a decent 11-second period. The morning is glassy, dead calm, making it as clean as a whistle. The combined energy is moderate (164), so there's a bit of push behind it. The water temp is a nice 82°, which is pretty much bang on average for this time of year. Aoshima is a beginner-friendly reef, so this is a good one for the learners to get a few clean, small ones.
We'll see a similar pattern on July 24th, with a 2 ft easterly swell and a glassy morning again. The energy is still moderate (144). The crowds are listed as "sometimes" here, so be prepared to share the peak.
The real excitement, though, is brewing for July 30th. That Thursday morning, the swell jumps to a solid 5 ft from the ESE, with a very long 16-second period. That's groundswell energy, folks. The combined energy is a whopping 1195 – that's strong to very strong. The wind is a light cross-onshore from the NNE, which isn't perfect, but at this size and period, it'll still be a proper session. This is a bit too big for groms and beginners, but for the experienced crew, this is the one to circle on the calendar. This long period groundswell is best handled by a reef like Aoshima, so it should line up nicely.
The rest of the period is a write-off. Mornings on the 15th and 16th have small 1 ft waves with clean offshores, but the energy is weak (70 and 58), so it's just tiny, rideable lumps. The weekend of the 19th and 20th is all onshore or cross-shore slop, and the 22nd has a pulse of moderate energy (149) but with awful onshore winds. Don't bother.
So, to sum it up: July 23rd and 24th offer clean, small, beginner-friendly waves. July 30th is a bold, long-range call for the experienced surfers looking for some real power. Keep an eye on that one.
Rusty, signing off.

Information about the Aoshima Surf forecast
The above surf forecast table for Aoshima provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aoshima can be found by selecting the local surf guide option on the grey menu. Our Aoshima surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Aoshima) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Aoshima may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
