The best time to visit Trat is during the dry season, which runs from November to February, offering pleasant weather for exploring the province.During these months, you'll experience lower humidity and less rainfall, with average temperatures around 25-30°C. This period is ideal for enjoying the beaches and islands of Trat, such as Koh Chang and Koh Kood, as the seas are calmer and great for swimming, snorkelling, and diving. It's also a great time for outdoor activities on the mainland, like visiting the Trat City Museum or exploring the local markets.The shoulder seasons, March to May and October, can also be good options if you prefer fewer crowds and don't mind slightly higher temperatures or the occasional shower. While it's hotter, the vibrant Songkran festival in April is a unique cultural experience that takes place during this time.Conversely, the rainy season from June to September brings heavier rainfall and rougher seas, which can sometimes disrupt island travel.
