Conditions at Nyang Nyang in May
May: Moving Into the Power Zone
May lights up as the Southern Ocean storm track aims more energy at the Indonesian islands. Average swell height climbs to 1.9m (6.2ft) and the mean period jumps to 14.1 seconds, ushering in a stronger, more powerful brand of surf at Nyang Nyang. The swell distribution shifts toward S and SSW: S contributes 31%, SSW 44.8% and SSE 11.4%, with 50% of all waves in the 1.5-2m (5-6ft) class and nearly 30% running 2-2.5m (6-8ft). That is proper late-season groundswell.
The trade wind regime is now well established, with ESE at 55.4% and SE at 17.1%, so surface conditions are windier than April. The ideal wind window drops to 32%, but the swell's energy is strong enough to keep the break grinding. Rainfall tumbles to 2.22 mm/day, air temp is 27.5°C and water temperature cools slightly to 28.8°C. If you want size and power, May delivers; just pick the mornings with lighter winds and chase the exposed SSW corners that handle the cross-shore texture.
