May: Monsoon Flip Begins
May marks the start of the southwest monsoon transition, and the surf character changes quickly. Average swell height drops to around 3ft (0.9m) with a 9.0s period. ENE (60%) and E (31%) swell still dominate, but more of the energy is in the 2-3ft (0.5-1m) range, with occasional 3-5ft (1-1.5m) sets. The wind field becomes much less monolithic: onshore easterlies are still common, but SW, WSW and W flow start to appear, pushing the ideal wind score up to 14%. This is when Boulevard begins to offer clean, rippable conditions for smaller boards, especially on a dropping tide. Average air temperature rises to 28.4°C, rainfall remains low at 4.87mm/day, and water temperature climbs to 29.3°C.
