In contrast, temperatures are more consistent in southern Thailand. However, there are differences between the eastern and western coasts. The rainy season hits the west, or Andaman coast, harder than elsewhere in Thailand. Therefore, it's best to visit during the drier months from November to April, when there's also great snorkelling and diving.
The east, or Thailand’s Gulf coast, lies outside of the country’s general weather pattern. This part of the southern peninsula and its islands instead feel the effects of the northeast monsoon, which sees rainfall from October to January, with the highest amount in November.
