Best Conditions

Swell Direction: The ideal swell direction is ESE (120°), with workable conditions from E to S (80°–170°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Aoshima Beach needs a minimum of 0.6m / 2ft to start working and handles swells up to 2m / 7ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 7 seconds, with 11 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the WSW (250°). The full offshore range spans SSW to WNW (210°–290°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for early morning dawn patrol sessions.

Tide: This spot works best at all tides. Optimal tide range is 0.2m–1.4m.

When to Go

Primary Season: The prime window at Aoshima Beach runs June, July, August, September (Jun–Sep). This is when swell consistency and direction align most reliably with the break.

Secondary Season: A secondary window opens October, November (Oct–Nov). While not as consistent, patient surfers can still score quality sessions during this period.

Season Notes: July cleanest. Summer typhoons deliver best swells.

Water Temperature: Expect water temperatures around 25°C / 77°F. A shorty or spring suit is recommended for longer sessions.
