Delhi recorded a maximum temperature of 36.2 degrees Celsius, which is two notches above the normal, while the minimum temperature was 23.2 degrees Celsius.
The national capital's air quality improved marginally on Sunday due to high wind speed, while favourable ventilation conditions are likely to keep it in the "moderate" category for the next three days, a government forecasting agency said.
The city registered a 24-hour average air quality index (AQI) of 117 on Sunday, an improvement from 165 on Saturday. An AQI between 0 and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.
Sporadic farm fires were observed on Saturday around Punjab and border regions but its impact has been negligible so far due to unfavourable wind direction and speed, the System of Air Quality and Weather Forecasting and Research (SAFAR) said.
However, it said that late withdrawal of monsoon and associated stagnant winds are likely to influence Delhi's air quality negatively by the weekend.
In neighbouring Uttar Pradesh, light rains and thundershowers occurred at isolated places, with the meteorological department predicting mostly dry weather in the state on September 28 and September 29.
The maximum and minimum temperatures in Punjab and Haryana hovered around 35 degrees Celsius and 21 degrees Celsius respectively, with parts of both the states witnessing overcast conditions.

Road connectivity has been affected in Morigaon, Nagaon and West Karbi Anglong districts while 43 relief camps have been set up in three districts so far, the ASDMA said.
Meanwhile, the weather department said, "Conditions are becoming favourable for withdrawal of monsoon from west Rajasthan and adjoining areas from September 28."
Data suggests the country has received 9 per cent more rainfall than normal until September 26 and the rainy season is most likely to end on an above-normal note.
Mahesh Palawat, the vice president of private forecaster Skymet Weather, said, "The withdrawal of monsoon from west Rajasthan is likely to start from tomorrow (Monday). It looks like monsoon will withdraw on an above-normal note."
Rainfall in the range of 96 to 104 per cent of the Long Period Average (LPA) is considered as 'normal', while precipitation in the range of 104 to 110 per cent of the LPA is 'excess'.
Nine states have received excess rainfall, while 20 states have recorded normal precipitation, the data shows.
