Hamaatsuma is Hokkaido's most accessible surf spot, a beginner-friendly beachbreak south of New Chitose Airport with consistent 2-foot waves and full facilities. The water is cold year-round—even summer requires at least a 3/2 wetsuit—but the tradeoff is uncrowded waves and an authentic Japanese surf experience far from the Tokyo masses. August through November offers the best combination of warmer water and typhoon swells.

The Hamaatsuma Beach profile favors the recorded tide range, ideally between 0.2m and 1.3m on the local tide chart. Compare this preference with the forecast tide and local conditions before choosing a session.
The Hamaatsuma Beach profile uses wind from N (0°) as its preferred direction, with an offshore range of 320° to 40°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.
The Hamaatsuma Beach scoring profile favors swell from SSE (110° to 190°), a swell-height range of 0.6m to 2m, and a reference period of 11s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
