Ishizakigawa (Miyazaki)

Ishizakigawa is a rivermouth surf spot near Miyazaki City with a sandy bottom and consistent left-and-right wave options. The break is described as a “regional classic,” with peeling sections that can start working at under 1 m and build up to around 2 m plus when the sandbars and swell align. In terms of swell, it performs best with east-to-northeast directions (east, southeast, northeast), with height windows commonly cited around 0.6–2.0 m. Ride length varies with conditions: many sessions are shorter (under about 50 m), while better sandbar alignment on good days can extend rides to roughly 50–150 m—often with the right side producing longer runs. Wind-wise, west winds are the preferred direction and are described as offshore here, helping keep waves cleaner. Lighter conditions are often seen early, with sea breezes building later in the afternoon; the most consistently favored months are July through October, overlapping with typhoon-season swell patterns. Safety is a key consideration at a rivermouth: rip currents are possible, and submerged rock/reef sections plus river debris after rain are reported hazards. After typhoons or heavy rainfall, sandbars may shift significantly, so it’s important to reassess conditions before paddling out. Weekends tend to draw more riders than weekdays, so be mindful of crowded lineups and local surfers during peak times.
