Conditions at Ral Island in June
June: The Small and Clean Grovel
June is full-on low season for wave size. Average swell height drops to 2.6ft (0.8m) and the average period shortens to 8.0 seconds. ENE swell leads the wave rose at 44.3 percent, with NE at 36.1 percent and E at 10.9 percent. The favorable N, NNE, NNW and NW window nearly disappears, adding up to only 5.9 percent of the energy. Almost all surf is 2 to 3ft (0.5 to 1m), with only slithers of 3 to 5ft (1 to 1.5m) ENE groundswell.
On the bright side, ideal wind reaches 63 percent, the highest of the year so far. The trade wind flow is consistently out of the E, ESE and SE, making conditions clean and largely cross-offshore. Water temperature is warm at 29.7°C, air sits around 28.2°C and precipitation is 6.96mm per day. June is about enjoying fun, manageable waves in clean tropical conditions rather than chasing size.
