Conditions at Diego Garcia Island in June
June: Southerly Energy, Hostile Surf
June is a heavy month in the water but a poor one for quality at Diego Garcia. The average swell height climbs to around 8ft (2.4m) with a 12.1s period, and the swell distribution is almost exclusively SSE (37.5%), SE (13.1%) and S (12.4%). A full 25.4% of the SSE swell falls in the 6-8ft (2-2.5m) range, with another 1.2% over 8ft (2.5m); the SE direction also adds a large 10% chunk in the same heavy class. Yet the wind is ideal for surfing just 2 percent of the time. ESE (39.7%) and SE (40.7%) dominate, including strong 20-30 and 30-40kph bands. The combination of powerful but wrong-direction swell and near-constant onshore trade winds creates blown-out, dangerous surf. Water temperature cools to 27.6°C and rainfall is minimized at 3.64mm/day, but the dry, windy weather does little for surf quality. This is a month for bigger boards and low expectations.
