The climate of Rajasthan in northwestern India is generally arid or semi-arid and features fairly hot temperatures over the year with extreme temperatures in both summer and winter. The hottest months are May and June. The monsoon season is from July to September; however, rainfall remains moderate.[1]

History

Under the Köppen climate classification the greater part of Rajasthan falls under Hot Desert (BWh) and remaining portions of the state falls under Hot Semi Arid (BSh); the climate of the state ranges from arid to semi-arid. Rajasthan receives low and variable rainfalls and thereby is prone to droughts. As Rajasthan is the dry and hot state, Unbelievable hailstorm covered Nagaur, Rajasthan in a thin snow-like icy blanket in December 2019. Later on, it is clarified that this is not a snowfall but a hailstorm, endorse by western disturbances. The climate has changed in winters like never before.[2]

Seasons

Summer

Due to the Desert Geography, frequently climb above 40 to 45 degrees Celsius in most places. Due to its location, summers are the longest season in Rajasthan. In this time tourist activities are very low.

Winter

The cold weather commences early in October and ends around the end of February and sometimes the temperatures reach nearly 2-degree Celsius [*record in 1964 in JAIPUR the temperature reached 0-degree Celsius on 13 December.]

Monsoon

The state has two distinct periods of rainfall: rainfall due to the South-West Monsoon after summer and rainfall due to Western Disturbances.

Disasters

Drought and famine

Rajasthan receives low and variable rainfalls and thereby is prone to droughts. Availability of water is less due to the absence of rivers and lakes.

Floods

Occasional floods in cities due to improper drainage occurs. Sometimes floods also occur in western Rajasthan due to impervious base rocks.

Pollution

In some industrial and urban centers pollution has been reported occasionally.
