Season planner for Ari Atoll
Ari Atoll is diveable year-round, but the Maldives monsoon pattern changes sea state and visibility. The drier northeast monsoon (roughly December to March) usually brings calmer seas and better visibility, while the southwest monsoon (roughly May to October) brings more wind, rain, and plankton that can reduce visibility but increase manta activity. Water temperature stays tropical (commonly 27°C to 30°C), so planning is more about surface conditions, crossings, and what wildlife you want to prioritize.
