May: Fun-Sized Spring Bowl
The winter swell machine winds down in May, but Low Island remains very surfable. Average wave height drops to 5.6ft (1.7m) with a 10.2s period - still enough period to keep the swell organized. The wave rose is dominated by a broad SW/WSW band: SW at 27.0%, WSW at 23.6%, and SSW at 16.7%. Much of this is in the 3.3-6.6ft (1-2m) range, which is ideal for a good shortboard or a step-up. Wind quality stays reasonable, with 32% ideal offshore wind, although NW flow begins to increase as the marine layer warms. Water temperature climbs to 8.1°C (46.6°F), air temperatures average 7.9°C (46.2°F), and May is one of the drier months with only 3.84mm/day of precipitation.
