Climate & Weather Overview

India (National Climatic Context)

Mid-November in India marks a post-monsoon transitional phase, as reflected in long-term climatological observations of the India Meteorological Department (IMD). Across most of the country, weather conditions are stable and predominantly dry, characterised by moderate daytime temperatures, cooler nights, and declining humidity. While limited rainfall may persist along parts of the southeast coast under the northeast monsoon, the subcontinent as a whole enters a calm and comfortable climatic window conducive to international travel and global gatherings.
