May marks the start of the southwest monsoon. Rainfall increases sharply (averaging 14 rain days, 220mm total), though most rain falls as short afternoon thunderstorms rather than all-day downpours. Mornings are typically sunny. Sea conditions are slightly choppier; seaplane transfers may have occasional delays.
Rates drop sharply from May 1st onwards. Some seasonal-only resorts close briefly for staff training and refurbishment in early May. Hanifaru Bay (UNESCO Biosphere Reserve in Baa Atoll) opens for manta ray season — one of the world's premier manta encounter sites. Bring waterproof options for excursions.
