Many people are apprehensive about vacationing in Thailand in May due to the increased occurrence of rainfall during this period. However, it's important to note that the majority of rainfall tends to happen towards the end of the month, and its duration is unlikely to significantly impact your vacation. Furthermore, in popular seaside resorts such as Phuket, Samui, Pattaya, and Krabi, rainfall occurrences are less frequent than on the mainland. Therefore, embarking on a spring vacation to Thailand can be done without fear of disrupting your cultural exploration - the rains may even refresh your city walks. And if your goal is to immerse yourself in the sea waves, they will only add variety to the bright and sunny days.
