Thailand is a large country. It occupies a larger amount of space than California does, and like California, it has a diverse environment. There are many unique landscapes in Thailand, from mountains and forests to beaches and islands.
There is one thing that is more or less present no matter where you are in Thailand, and that is the amount of rain that falls here. When rain falls onto the ground, it finds its way to an ocean by, thanks to gravity, trickling down mountains. Over time, these trickles create streams, creeks and rivers that drain into the Gulf of Thailand.
While some amount of rain, no matter how small, falls in nearly every environment in the world, Thailand is unique because it has three very distinct seasons, or seasons that are very different from one another: rainy, cool and hot. The rainy season lasts from July to October, the cool season is between November and February and the hot season lasts from March to June. Because of this climate phenomenon, or event, it only rains substantially, or enough, for four months each year. The rest of the year is somewhat dry, leaving people to use the water that fell during the four-month shower for all eight of the other months.
