The best time to visit Ang Thong is during the dry season, which runs from November to February.During these months, the weather is typically sunny with lower humidity and average temperatures ranging from 25–30°C. This makes it ideal for exploring the Ang Thong National Marine Park, as the sea conditions are generally calm and clear for activities like snorkelling, kayaking, and island hopping. It's also suitable for hiking to viewpoints on islands like Koh Wua Talap, offering spectacular panoramic vistas.For travellers who prefer to avoid the busiest tourist period, the shoulder months of March and October can also be good options. While temperatures might be slightly higher in March and there's a slight increase in rainfall in October, you can often find good value on accommodation and experience the park with fewer crowds.
