May: The South Pacific Roars to Life
May is when the wet season begins in Earnest, but it also brings the season's first real size. Average swell height climbs to 1.3m (4-5ft) and the average wave period reaches 14.1s - the longest of any month.

However, ideal wind drops to 23 percent, and SE, SSE and S winds become more frequent, making the surface that much harder to keep clean. Rain increases sharply to 7.83mm/day, but water stays warm at 29.4°C and air temperatures average 26.6°C. May is a month for the experienced surfer - the swell is pumping, but you need to be selective with the wind.
