The best time to go to Ko Mook is during the dry season, which runs from November to April.
This period sees plenty of sunshine and very little rain, making it ideal for enjoying the island's beaches, swimming, and boat trips. The sea is typically calm and clear, great for snorkelling and diving around the coral reefs. It's also the best time to visit the famous Emerald Cave, as conditions inside are at their most accessible and pleasant.
For families, visiting between December and February is particularly good. The weather is consistently excellent, and the sea conditions are usually very gentle, which is great for children playing on the beaches. While it's a popular time, the island generally maintains a relaxed pace, offering a comfortable holiday experience.
Couples looking for a more tranquil experience might prefer the shoulder months of November or April. The weather is still excellent, but there are fewer visitors, meaning the beaches and attractions feel more secluded.
