The national capital today experienced the hottest January 30 in the last five years with the maximum temperature settling at 27.2 degrees Celsius, five notches above the season's average, the Met office said.
The weather office referred to the Western Disturbance persisting in the northern parts of India as a reason behind the sudden increase in mercury.
"As the Western Disturbance approach still persists in northern India at a few kilometres above sea level, it caused sudden winter rain in Himachal Pradesh leading to the rise in temperature," said an official of the India Meteorological Department (IMD).
The weather office has forecast that mercury would come down after the Western Disturbance passes the northern areas.
"There would be a clear sky on Sunday in Delhi while shallow to moderate fog may occur in the morning," the IMD official said.
Sunday's maximum and minimum temperatures are likely to hover around 25 and 11 degrees Celsius, respectively.
Saturday's minimum temperature settled at 13.2 degrees Celsius, four notches above the season's average, while the maximum humidity was recorded 98 per cent.
Friday's maximum temperature was recorded 25.4 degrees Celsius, three notches above the average for this time of the season.
