The following are the reasons:
1) relief and topograph- the windward side of mountains hills receive more rainfall than leeward side.

2)latitudinal extent- the  tropical and coastal regions and the plains receive more rainfall that the plateau and desert region in the interior.

3) the vagaries of the monsoon- the unpredictability of the monsoon along with phenomena  like monsoon troughs and  depression lead to unequal distribution of rainfall.
