The climate of Rajasthan greatly varies throughout the state. Rajasthan lies to the north west of India, just above the Tropic of Cancer. In the west, Rajasthan is relatively dry and infertile; this area includes some of the Thar Desert, also known as the Great Indian Desert. The Aravalli Hill ranges tower over the Thar Desert. They are famed for the hill station of Mount Abu that is home to the famous Dilwara Jain Temples. The presence of the desert makes the summer days very hot and nights very cold. Nighttime temperatures in winters can reach -1°C, as happened recently in Churu district in north Rajasthan. Jaisalmer and Barmer districts also lie in the western Rajasthan, and every winter tourists flock to these districts to take camel rides on the shifting sand dunes. Jaisalmer is known for its peculiar yellow sandstone, which was used to construct the "golden" Jaisalmer Fort. The maximum daytime temperatures in summers can reach 45°C. However, winters in Rajasthan are more or less pleasant, and is the best time to visit this state.
The southern districts of Udaipur and Chittor are more or less fertile. Infact, Udaipur is known as the Lake City because of its many lakes and canals that reminds one of Venice. The Mewar region, also to the south of the state, was the scene of many battles during the Mughal rule.
The Chambal River runs through the rocky northeastern region. The deep gullies and ravines of Chambal were once hideouts of the infamous bandits of Chambal. However, now they are a quiet tourist destination for people from around the country.
