Cotton is a plant that needs a long frost-free period, a lot of heat and plenty of sunshine. It prefers warm and humid climate. Cotton seeds will have a small germination rate, if the soil temperature is below 60°F (15°C). During active growth, the ideal air temperature is 70 to 100°F (21-37°C). Therfore, All mentioned features are best suited for the cultivation of cotton.
Climatic requirements for cotton:

Temperature- 21-30 degree Celsius
Rainfall: 50-100 cm
210 frost free days
Soil : Black soil of Deccan and Malwa Plateau
