Conditions at Omaezaki in June
June: Baiu Rain and S/SSW Swells
June is the beginning of the Japanese summer wet season, and it shows in both the clouds and the surf. Swell direction is strongly from the S/SSW window: S 19.9%, SSW 22.2% and SW 7.7% combine for almost half the total swell energy. But these are predominantly windswells generated by the southwest monsoon, with an average period of 7.7s; they arrive at 2-5ft with occasional bigger SSW pulses in the 1.5-2.5m range. The surface is frequently lumpy under persistent SW/WSW winds.
Wind statistics confirm this: WSW (15.0%), E (14.6%), ENE (13.2%) and SW (12.0%) dominate, while true offshore wind is only ideal 21% of the time. Expect onshore bumps unless a passing low flips the wind to N/NNE. Air temp averages 22.1°C and water hits 21.4°C. The Baiu front brings 8.34mm/day of rain, so persistent showers are part of the trade-off for consistent south swell.
