May marks the beginning of the summer season in Thailand, which is characterized by high temperatures and increasing humidity. The weather in May is generally hot and sunny, with occasional showers and thunderstorms. The country experiences a transition from the cool, dry season to the wet season during this time.

In May, Thailand experiences high temperatures across the country. The average daily temperature ranges from 29°C (84°F) to 35°C (95°F). The northern regions tend to be slightly cooler, with temperatures averaging around 31°C (88°F), while the coastal areas, such as Bangkok and Phuket, can reach temperatures as high as 35°C (95°F).
