Climate of Haryana is similar to other states of India lying
in the northern plains. Haryana can be divided into two natural areas,
sub-Himalayan terrain and the Indo-Gangetic plain. The plain is fertile
and slopes from north to south with a height above the sea level averaging
between 700 and 900 ft.
The south-west of Haryana is dry, sandy and barren. There are no perennial rivers in Haryana, Ghaggar being the only river, which flows through the northern fringes of the state. Haryana is very hot in summer and cold in winters. The temperature falls to the lowest in January and reaches upto 50o C during the months of May and June.
About 80% of the rainfall occurs in the monsoon season during the months of July and September and sometimes causes local flooding. Rainfall is varied with Shivalik Hills region being the wettest and the Aravali Hills region being the driest.
