Conditions at Airport in June
June: Southern Ocean Push
The Southern Ocean enters its most active phase in June, and Airport feels it immediately. Average swell height jumps to 7ft (2.1m) with a period of 14.3s, pushing a large share of waves into the 5-8ft (1.5-2.5m) range. Direction leans heavily on SSW (41.1%), S (30.9%) and SSE (8.8%), while SW contributes only 2.7%. This is classic South Indian Ocean groundswell, generated by intense winter lows sweeping below Australia. Airport's west-facing bathymetry catches a lot of that south-southwest energy, but the quality is best when the swell direction trends a bit more west.
The wind regime is offshore but strong: ESE (58.8%) and SE (21.7%) dominate, with many readings in the 20-30kph range. This keeps the wave faces clean but can add a tricky sideshore-offshore texture on the biggest days. Ideal wind sits at 57%. Water temperature cools to 28.0°C, air to 24.2°C, and rainfall is minimal at 1.57mm/day. This is serious winter surf for Indonesia.
