May: Southern Hemisphere Swell Machine Turns On
May signals the transition from dry season to wet season, and the surf responds with the longest average period of the year at 14.1 seconds. Average height jumps to 4-4.5ft (1.3m), and the distribution improves with 68.8 percent in the 3-5ft (1-1.5m) range and 19.1 percent in the 5-6.5ft (1.5-2m) range. A small but notable 1.3 percent of the swell reaches 6-8ft (2-2.5m). The SSW direction accounts for 94.2 percent of the energy, with another 5.3 percent from the SW. The Intertropical Convergence Zone brings more convective activity, with precipitation jumping to 7.83mm/day, but ideal offshore wind still occurs 34 percent of the time, especially in the morning. Air temperature averages 26.6°C and water temperature reaches 29.5°C. For surfers willing to work around the afternoon storms, May delivers powerful, long-period waves.
