Conditions at Choshi in June
June: Early Summer Slump and Short-Period Chop
June is the heart of Choshi's summer lull. The average swell height falls to 4ft (1.3m), and the period drops to its annual low of 8.6s, meaning most waves are weak and short-period. The directional data continues to favor E/ESE/SE windswell, with ESE and E combining for nearly 50% of the observations. The south/southeast component remains present at around 28%, but the wind becomes the limiting factor. The North Pacific High strengthens, driving SSW winds at 12% and S/SW onshore flows that regularly chop up the surface; only 31% of the time does the wind blow from a favorable offshore direction. Air temperatures are comfortable at 21.3°C, water warms to 18.5°C, and precipitation rises to 5.97 mm/day as the rainy season begins. Surfing is possible on the better E-SE days, but Choshi is largely a summer grovel zone, with small, soft, wind-affected waves.
