Conditions at Herradurra in May
May: Cooler and More Powerful
May marks the start of the fair season as the Southern Ocean storm track becomes more active. Ideal wind drops slightly to 89 percent, with S wind at 77.8 percent and a growing number of 20-30kph pulses (7.6 percent). The wind is still fundamentally offshore, but the stronger S flow adds more texture to the surface than during the summer months.
Swell now averages a solid 5ft (1.5m) at a 13.7s period, and the SSW window accounts for 87.8 percent of the total energy, with SW at 11.3 percent. Waves in the 5-7ft (1.5-2m) range jump to 38.2 percent, and 2-2.5m (6-8ft) sets appear at 6.8 percent. This is a more powerful, heavier wave compared to January, but it still offers fantastic conditions when the wind relaxes. Air temperature averages 18.2°C, water drops to 17.9°C, and rainfall remains negligible.
