The weather during Chhath Puja is generally mild, with daytime temperatures ranging from 20°C to 30°C in most regions. Nights can be cooler, especially in northern India, with temperatures dropping to around 10°C–15°C. However, post-monsoon showers may still occur, particularly in areas where the monsoon withdrawal is delayed. These conditions can affect the preparation and execution of rituals, which are often conducted at sunrise and sunset.
