Why Mumbai recevies more amount of rainfall than Pune despite of having less distance among them ?

Mumbai receives more rainfall than Pune as it is located on the coast and Pune is in the interior. Mumbai lies on the windward side of Western Ghats while Pune is located on the leeward side. Windward refers to the direction from which the rain-bearing south west monsoon winds approach the land from sea. Lee ward refers to the region that is shielded from these winds by a natural barrier, in this case, the hills of Western Ghats. This region is drier and is referred to as rain-shadow due to this feature.
