The weather does not stay the same all year. It changes in a pattern we call seasons. In Thailand we have three seasons: the hot season (summer), the rainy season, and the cool season (winter).
Summer comes around March to May. It is hot and sunny, and we see lots of mangoes. The rainy season comes around June to October. Dark clouds bring rain almost every day, and everything turns green. The cool season comes around November to February. Mornings are chilly, the sky is clear, and we may see mist.
Example: Look at a calendar. Point to April — hot season! Point to August — rainy season! Point to December — cool season! The seasons go round and round every year.
