Koh Samui in April experiences a transitional period between the dry and wet seasons. This typically translates to hot and increasingly humid conditions, with rising temperatures and a greater chance of rainfall compared to the preceding months. Sunshine remains prevalent, but the frequency and intensity of showers tend to increase as the month progresses. Sea conditions are generally calm, making it suitable for water activities.
Understanding the climatic conditions during this period is essential for travelers planning a visit. Awareness of the increasing humidity and likelihood of rain allows for appropriate packing and activity planning. This transitional month offers a balance between the dry season’s consistently sunny skies and the lush greenery that the approaching wet season brings. Historically, April marks the beginning of the Songkran festival, the traditional Thai New Year, which often influences local events and tourism.
