Kugenuma Beach is a sandy-bottom beach break located in Fujisawa, Japan, offering both lefts and rights along Japan's coastline.

Rated as beginner-friendly difficulty with very crowded conditions, this beach break is a worthy destination for surfers looking beyond the usual suspects.

Best Conditions

Swell Direction: The ideal swell direction is SSE (160°), with workable conditions from ESE to SSW (120°–200°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Kugenuma 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 10 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the N (0°). The full offshore range spans NW to NE (320°–40°). 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–1.2m.

When to Go

Primary Season: The prime window at Kugenuma Beach runs July, August, September (Jul–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: Typhoon season only. Often flat outside storm windows.

Water Temperature: Expect water temperatures around 23°C / 73°F. A shorty or spring suit is recommended for longer sessions.
