What Are the (2) most important climatic factors for the Indian people?

Latitudinal Location and Distance from the Ocean/Sea.

Explanation:

Latitudinal Location because it is the distance from the equator. The farther away from the equator you get, the hotter it gets, and vice versa.

Distance from the ocean/sea because the ocean/sea is a heat reservoir. It stores heat, and lets it out when its cool, therefore making places near the sea have either colder or warmer temperatures depending on the time of year.
