The subtropical desert climate there results from persistent high pressure and subsidence at that latitude. The prevailing southwest monsoon winds that bring rain to much of the subcontinent in summer tend to bypass the Thar to the east. The name Thar is derived from thul, the general term for the region’s sand ridges.

The Climate in the Thar desert is like any other desert. Hot in the day and cool at night. The summer days are really hot and the nights are cool but the winter days are warm and the nights are cold. In the summer there is little to no rain. (as seen in the chart) From the heat there are many dried up rivers.
