Meteorologists and weather bloggers have observed that winter days in Chennai are getting warmer over the past three decades. The characteristic chill weather experienced during daytime in January and February is slowly fading.
Weather blogging site Chennai Rains conducted a study in which it was observed that the daytime temperature during January and February has remained above normal since 1980. The monthly mean temperature has been steadily hovering above average temperature by 0.2 degree Celsius to 0.5 degree Celsius in January.
Say bloggers, There has been a steady rise in daytime temperature in January and February, particularly after 1999. While the average monthly mean temperature hovering above 0.5 degree Celsius may look normal, it means the city is experiencing a warmer weather on many days. The monthly mean temperature has reached 31 degree Celsius some years.
Over the past three decades, 2016 witnessed the warmest January with the monthly mean temperature touching 31.2 degree Celsius. While the days are getting warmer, nights are becoming mildly cooler and the minimum temperature has stayed close to 20 degree Celsius. Drier weather during January and February is cited to be one of the reasons for such variations.
