April marks the transition to the southwest monsoon. Weather remains warm and largely sunny, but the first afternoon showers begin to appear (averaging 9 rain days). The sea temperature peaks at 29°C — the warmest of the year. Sunrise and sunset remain spectacular.
Easter weekend brings a short crowd spike, after which rates begin dropping into shoulder pricing. Ramadan often falls in this month (varies by Islamic calendar) — resorts remain fully operational, but expect quieter daytime ambience and special iftar dinners. Local-island excursions may have limited daytime food service.
