Delhi recorded its coolest May in 36 years with excess rainfall bringing the average maximum temperature down to 36.8 degrees Celsius this time, the India Meteorological Department (IMD) said on Wednesday.
Delhi Weather in May: Shallow fog occurs when visibility hovers between 501 and 1,000 metres and the high moisture content in the air, calm winds and a significant difference between the daytime and night-time temperatures create conditions that are favourable for the formation of fog
