Conditions at K59 in May
May: Southern Hemisphere Peak With a Price
May is the apex of the Southern Hemisphere swell window. The average height climbs to 1.4m (4.6ft) and the period hangs at 14.2 seconds, the highest of the year. The direction is almost exclusively SSW - 87.5% of swell energy - with S at 7.9% and SW at 4.1%. The big news is the distribution: 1-1.5m (3.3-4.9ft) still leads at about 60%, but 1.5-2m (4.9-6.6ft) jumps to 22% and even 2-2.5m (6.6-8.2ft) appears. This is the closest K59 gets to consistent, firing, overhead surf without a tropical assist. However, wind quality deteriorates. The N/NNE/NE/NNW offshore quadrant shrinks to a minor presence, and light onshore or variable winds increase; ideal-surfing wind drops to 52%. Air temperatures average 27.7°C, water temperature hits 30.2°C, and rainfall ramps up dramatically to 5.26mm per day. The waves are there - you just need to hunt for the protected morning windows.
