Conditions at Cables in May
May: Winter's First Big Pulses
May delivers the highest ideal wind percentage of the entire year - 48% - while the swell is getting seriously good. Average height jumps to 2.2m (7ft) and period remains 12.7s. The direction spread widens in a way that benefits Cables: SW still leads at 42.1%, but WSW jumps to 16.0%, W to 3.7% and WNW to 1.4%. That increasing west component is exactly what this west-facing spot wants, producing more direct and powerful lines.
With E (11.7%) and ENE (10.8%) both prominent, plus ESE at 8.2% and SE at 6.8%, the offshore flow is strong and reliable. The wind rose also shows a developing NE/NNE component as the synoptic pattern strengthens. Rain increases to 2.88mm/day and air temperature cools to 18.5°C, with water at 20.7°C - still warm enough for a thin wetsuit. This is the month to keep an eye on synoptic charts; the Southern Ocean is firing and Cables is set up to handle the bigger groundswell.
