The best time to go to Dawei is during the dry season, which runs from November to February.During these months, you'll experience consistently sunny days and comfortable temperatures, typically ranging from 25°C to 30°C. This period is ideal for exploring Dawei's beautiful beaches, such as Maungmagan Beach, and for outdoor activities like island hopping to the Myeik Archipelago, which is less accessible during other times of the year. The calm seas make boat trips particularly pleasant.March and April are also part of the dry season, but temperatures can rise significantly, often exceeding 35°C, making some daytime activities less comfortable. While still suitable for beach holidays, you might find yourself seeking shade more often.The rainy season, from May to October, brings high humidity and frequent heavy downpours, especially from July to September. Many smaller businesses and some island excursions may close or be limited during this time due to weather conditions.
