As Kampung Serdang Baru is a fantastic gateway to the Perhentian Islands, the best time to visit is during the dry season, which runs from March to October.This period offers clear skies, calm waters, and plenty of sunshine, making it great for island hopping, snorkelling, and diving around the Perhentian Islands. You'll find that all the tour operators and boat services are fully operational, ensuring you have the best selection of activities and excursions.For those looking for a quieter experience, the shoulder months of March, April, September, and October are ideal. The weather is still excellent, but there are fewer crowds compared to the peak months of May to August. This means you can enjoy the natural beauty and activities with a bit more serenity, often finding better deals on accommodation and tours.The monsoon season, from November to February, brings heavy rainfall and rough seas, leading to many services on the islands closing down.
