According to the Met department, the early morning will, now onwards, become even cooler than the last week due to the post-monsoon effect.

“The period from October 1 to December 31 is called post-monsoon, and during this time the minimum temperature starts falling. It happens because this part of the earth becomes less exposed to the sun’s heat,” M Mohapatra, director, India Meteorological Department (IMD), said.

Thus, the drop in the night’s and the early morning’s mercury will continue as the winter approaches.

Weather analysts, however, added that the heavy monsoon, which had gripped a large part of northern, north-eastern and central Uttar Pradesh is now expected to come to an end, leading to a slight rise in the daytime mercury. The overall weather will remain cool, despite a high humidity level and partially cloudy sky, with moist and cool easterly winds.

“The monsoon withdrawal is most likely to begin within the next 10 days. The minimum temperature will drop as part of the post-monsoon effect as winds continue to blow from the east. The temperature will further drop and air quality may begin worsening as well with a change in the wind direction towards the middle of October,” Mahesh Palawat, director of private weather forecasting agency Skymet, said.

When the wind direction changes to westerly or north-westerly, it brings with it cold and dryness. Not to mention, westerly and north-westerly winds also bring smoke from stubble-burning in neighbouring Punjab, Haryana, and Pakistan that lead to the worsening of air quality around the NCR.

Tuesday’s maximum temperature hovered around 32.8 degrees Celsius, two notches below the season’s average while the minimum temperature was recorded at 23.8 degrees Celsius, a notch above the season’s average. Monday’s maximum and minimum temperatures hovered around 32 degrees Celsius and 23.8 degrees Celsius respectively.

The humidity oscillated between 91% to 62%, weather analysts said.

“Wednesday is likely to see a light drizzle in certain isolated pockets. The maximum and minimum temperatures are likely to remain the same, hovering around 33 degrees Celsius and 24 degrees Celsius,” an official at IMD said.

Last week saw comparatively lower day as well as morning temperatures due to the induced effect of the rain close to Noida and adjoining regions. However the day temperature is set to increase by a degree or two, IMD officials said.

Meanwhile, the air quality remained satisfactory in the Noida, Ghaziabad and Greater Noida regions. The Air Quality Index (AQI) readings on a scale of 0 to 500 were 82 for Noida, 85 for Ghaziabad and 84 for Greater Noida.
