Pulau Perhentian experiences closure from November through early March due to the monsoon season, characterized by heavy rains and strong winds, rendering travel unsafe. The islands typically reopen from mid-March to mid-November, offering warm and sunny weather to welcome travelers.

July and August stand out as the most sought-after months to explore Pulau Perhentian, owing to optimal diving conditions. However, for budget-conscious travelers seeking quieter beaches and less crowded resorts, starting from Mac would be advisable for planning your trip.
