Conditions at Ozaki in May
May: Cleaner but Shorter Period
May is a month of cleaner conditions but a noticeable loss of power. The ideal offshore wind window climbs to 23%, with WSW and SW winds blowing a combined 20.5%, providing plenty of groomed surface conditions for the east-facing coast. However, the average wave period drops to 7.7 seconds, signalling more locally generated windswell than true groundswell. Swell direction becomes heavily SE/SSE dominated, with SE alone at 34.4% and SSE at 26.5%; most waves stay in the 0.5-1m range, though solid 1-1.5m (3-5ft) energy is present around 12% of the time. Air temperatures are mild at 19.7°C, water is a pleasant 21.6°C, and rainfall ramps up to 6.07mm per day. It is a great month for logging waves on a smaller board when the offshore breeze lines up.
