The climate of Haryana over most of the year is of a pronounced continental
character. It is very hot in summer and markedly cold in winter. The rainfall
in the region is low and erratic except in parts of the Karmal and Ambala
districts. The rainfall is unevenly distributed during the year except
for two well marked seasons. One is the monsoon period lasting from the
middle of June to the end of September on which autumn crop and spring
sowing depend and the other is the winter rains which occur from December
to February, benefiting rabi crop. Rainfall is meager, particularly in
the districts of Mahendragarh and Hissar.
