Conditions at Aramoana in May
May: Big Southern Swells, Autumn Charm
May brings the year's largest average wave height at 7ft (2.2m), with the average period peaking at 11.6s - properly long-period and powerful. The Southern Ocean is firing, but the direction mix is heavily weighted toward SSW and SW, which is not ideal for Aramoana's NE-facing sand. True N-ENE swell drops to one of its lowest percentages of the year. Still, with ideal wind conditions occurring 27% of the time, there are quality windows, especially when a WSW/SW offshore flow aligns with the better NE/ENE wraparound energy. Air temps fall to 9.8°C, water temp drops to 11.6°C, and precipitation is 2.00 mm/day. The key in May is patience: wait for the right synoptic setup rather than chasing every big raw swell.
