With so many regions, Mexico has a variety of climate conditions. Inland, where the elevations are higher, the climate is moderate and drier. Meanwhile, in the coastal plains, the weather is hotter with more humidity.
Mexico generally has two seasons: dry and rainy. The rainy season is from June to October, while the dry season is from November to May. The coolest months are usually on December to February. Winds from the North make the inland regions downright chilling, even freezing.
