Waves breaking on sandy bottom, varied conditions
Itsuki is a coastal beach break located on Japan's Sea of Japan coast, facing westward toward open water. The spot features a sandy beach bordered by rocky formations and dense forest vegetation. Moderate wave exposure creates consistent small swell conditions averaging 1.17m. Wind reliability is relatively low at 32.6%, with average winds of 10.5 knots, suggesting this is not a primary wind-dependent destination. The presence of offshore boat traffic indicates a working coastal area with maritime activity. The beach is narrow with industrial and agricultural development inland, limiting rider access and recovery space. Best wind conditions arrive from the north (0°), providing side-shore winds parallel to the beach. The shallow waters near shore and rocky outcrops require careful entry and exit planning. This spot suits intermediate riders comfortable with smaller waves and variable wind conditions. Low water temperatures (averaging 16.1°C) require appropriate thermal protection. The spot's utility depends heavily on seasonal wind patterns and weather timing rather than consistent conditions.
