Pleasant September, which has grown a bit warm, feels a lot like October. This month is a transition period marked by the retreating monsoon before its complete withdrawal that brings on the heat.
The city’s day temperature was 32.8 degrees celsius on September 10, the highest maximum temperature recorded for the month so far, this year.
On Monday , the day temperature fell marginally to 32.1 degrees celsius, but turned out to be the second highest temperature recorded so far in the month.
Along with the rising day temperature, humidity is also on the higher side. Humidity is the amount of water vapour in the air which indicates the comfort level one feels when in the open. On Monday evening, the relative humidity too touched a sweaty 69, against a normal of 50.
The city’s temperature had crossed the 30 degrees celsius mark a few days ago.On Monday , the maximum temperature was 3.6 degrees C above normal. Sunday was even warmer when the mercury rose to 32.8 degrees C which was not only the highest day temperature for September so far, but a significant 4.3 degrees warmer than the normal.
AK Srivastava, head of the climate monitoring and analysis group of India Meteorological Department, told TOI that since rainfall has reduced significantly over a large part of central India, clear skies have resulted in more solar radiation reaching the earth’s surface.
Another official said during the days when cloudy skies prevailed over the city due to intermittent rain and thundershowers, humidity levels shoot up. “Whenever humidity levels go up, it feels hotter than it is,“ he said.
A K Jaswal, retired scien tist from IMD, said, “All of a sudden, clouding has reduced over Pune region. Hence, high intensity solar radiation has been reaching the earth’s surface due to the clear skies. Humidity levels have also increased because of moisture availability due to on and off rains as well as evaporation from wet surfaces. Hence, it feels very sultry these days. This phenomenon is usually noticed in October, but seems to have started a little early this year.“
