The climate is very different and is mainly determined by altitude. The mountain valleys have a mild climate all year round, the coastal areas have a humid subtropical climate and the lowlands are tropical forests. The Pacific coastal zone has a tropical climate with an abundant rainy season. The climate of the Andean highlands is temperate and relatively dry, and the Amazon basin, on the eastern side of the mountains, shares a climate with other rainforest areas.
Due to its location on the equator, Ecuador experiences little variation in daylight hours throughout the year. Sunrise and sunset occur at six o’clock every day.
