Surfing Machino Rivermouth: The Complete Guide

Machino Rivermouth is a sandy-bottom beach break located in Noto Peninsula, Japan, offering both lefts and rights along Japan's coastline. Machino Rivermouth sits on the exposed Noto Peninsula of Ishikawa Prefecture, jutting out into the Sea of Japan to catch maximum swell from Siberian winter storms. Rated as intermediate difficulty with uncrowded conditions, this beach break is a worthy destination for surfers looking beyond the usual suspects.

Best Conditions

Swell Direction: The ideal swell direction is NW (320°), with workable conditions from W to N (280°–360°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Machino Rivermouth needs a minimum of 1m / 3ft to start working and handles swells up to 3m / 10ft 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 ESE (120°). The full offshore range spans E to SSE (80°–160°). 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 mid tide. Optimal tide range is 0.3m–1.4m.
