However, the India Meteorological Department (IMD) is yet to declare the arrival of the monsoon in the capital.
"An official statement will be made after reviewing the rainfall data in the region," a senior IMD official said.
The MeT office had earlier said the monsoon would reach the capital on Thursday or Friday.
The southwest monsoon usually arrives in the national capital on June 27.
However, Mahesh Palawat, vice-president (climate change and meteorology), Skymet Weather, confirmed these are the first monsoon showers in the region. Most parts of the capital reported a fresh spell of rain.
The IMD has issued an orange alert, warning of heavy rainfall in some areas in the city on Thursday and moderate rainfall on Friday. The maximum temperature will come down to 34-35 degrees Celsius.
