Question

How would you describe the climate of SE Asia?

Answer 1

Tropical

Explanation:

Variations occur, as usual in any climate. But the "average" value and location of most SE Asian countries in the climate zones puts it primarily in the tropics.

The equator cuts through the middle of the south East Asian region.
Within 5°-6° north and south of the equator, high humidity and temperature are common, with little seasonal variations. Away from the equator, seasonal rainfall produces distinct wet and dry seasons. Summers are rainy.
