Conditions at Jailbreaks in May
May: The Monsoon Flips West
May marks the arrival of the southwest monsoon, and the character of the wave field changes completely. Average swell increases to 1.1m (3.6ft) and the period holds at 7.5s, but the direction shifts hard toward the west: WSW 22.9%, SW 16.6%, W 15.8%, SSW 13.0%. These westerly angles are outside the optimal swell window for Jailbreaks, which needs E/ESE/SE/SSE. Wind, ironically, becomes more offshore - W 35.0%, WSW 32.1%, WNW 15.3% - giving an ideal wind score of 41 percent. The rain ramps up to 6.42 mm/day, and air/water temps stay tropical (28.5°C / 29.9°C). The result is a frustrating paradox: clean offshore conditions over a shadowed, wrong-direction swell. Jailbreaks sees far less energy than the open-ocean numbers suggest, making it a month for elsewhere in the atoll.
