The city received 5.5 mm of rain between 8:30 AM to 5:30 PM today bringing down mercury below the 35 degree mark.
The MeT department today confirmed the arrival of monsoon in Delhi and other parts of Northern India today.
"The monsoon has arrived in several parts of North India and Delhi. The national capital and several parts of North India received widespread rain since yesterday," IMD director B P Yadav said.
"There is sufficient humidity and winds are flowing both from Arabian Sea and Bay of Bengal, which is a typical sign of monsoon's arrival in North India," he said.
The normal date for south-west monsoon's arrival in Delhi is June 29.
Following the rainfall, the day temperature was recorded at 32.7 degree Celsius which was three degrees below normal for this part of the year.
The minimum temperature was recorded at 26.1 degree Celsius, which was a notch below normal. This was mainly due to four mm rainfall the city received in the last 24 hours ending at 8.30 AM.
Residents experienced high humidity throughout the day as humidity levels hovered between 71 and 85 per cent.
Yesterday's maximum temperature was recorded at 36.6 degrees Celsius, which was normal for this part of the season, while the minimum was at 25.5 degrees.
