MUMBAI: Feel like you are in the midst of summer? Well, the weather is set to get hotter over the next few days. In an unusual fluctuation after a cool spell through the second half of November and the first couple of weeks in December, temperatures have now begun to surge.On Friday morning, Colaba recorded a minimum temperature of 24 degrees C, distinctly up from the 17-20 degrees C range in which the weather had remained during the nights in preceding weeks.
Weather bureau officials expect this heat to persist through Christmas, which is traditionally known for cool weather in the city (see table).
Deputy director general of the Regional Meteorological Centre, Colaba, C V V Bhadram said the city was experiencing hot days and nights in the last weeks of December due to the circulation of westerly winds over Mumbai. "The city is receiving westerly winds which are hotter than the northerly winds that cool the atmosphere,'' said Bhadram. The change has affected Mumbai and other parts of Maharashtra as well as Goa."The changing climatic system has resulted in moisture in the atmosphere, which in turn has increased the humidity,'' said Bhadram. The humidity has crept in after the first fortnight of the month. On December 10, the minimum temperature was 18.2 degrees C; on December 15, it fell to 17.2 degrees C; on the 16th, it rose to 19.5 degrees C; thereafter the mercury has climbed steadily, touching 24 degrees C on Friday.In fact, Friday's recording was just three degrees less than the minimum temperature recorded on a summer day-May 21, 2007. December is otherwise known to be pleasant in the city. For the last four years, the city has been cold in December with night temperatures dropping to 13-16 degrees.
