Durga Puja usually takes place in September or October, coinciding with the post-monsoon season in India. During this period, the weather is transitioning from the monsoon rains to the cooler winter months. In regions like Kolkata, where the festival is celebrated with great fervour, the weather is generally humid, with occasional rainfall. Temperatures are moderate, ranging between 25°C to 30°C, making it relatively comfortable for outdoor activities. However, sudden showers can occur, so it’s wise to be prepared for unpredictable weather.
