Nadahama

Nadahama (Kushima) is a sandy beach break known for producing both left and right waves. The wave quality is generally described as good, with a peaky, beach-break feel that can start working with small south swell (roughly from under 1 meter) and hold up into the around-1 meter+ range. When conditions line up, riders commonly get good day lengths, with overall ride quality depending strongly on tide, swell consistency, and wind. For wind, sources consistently point to north winds as the key direction, with typical conditions often described around 10–20 knots and light gustiness. North winds are described as offshore at this spot, which helps groom the wave faces. In the wider Kushima Coast area, afternoon thermal/sea-breeze influence is also a common pattern during late spring through summer, which can shape the day’s wind behavior. Safety is a central consideration: reef (and submerged rocks in some sections) is repeatedly highlighted as a hazard. At higher tides, reef patches may be harder to spot, so extra caution is needed when wading or paddling. During larger swells, riptides have also been noted. Lifeguards are described as seasonal—typically more likely during summer months—so conditions outside that period require extra self-reliance. Seasonally, the spot is commonly associated with late summer into autumn, including the typhoon window (September to October) when surf potential can increase. Water temperatures vary widely across the year (from the high teens in winter up to the high 20s in late summer), and a wetsuit is generally expected outside the warmest months.
