City meteorologists and weather enthusiasts are intrigued by the sharp temperature fluctuations in Mumbai over the past three days. The sudden dip to 13.7 degrees C on Monday (December 9) made it the coldest December day in nine years. However, within 48 hours, by Wednesday, the temperature rose sharply to 20 degrees C, leaving many puzzled by this “unexpected” and “unusual” phenomenon.

Officials from the India Meteorological Department's (IMD) Regional Meteorological Centre (RMC) in Mumbai, however, stated that this variation in temperature was anticipated. After enduring several days of unusually high temperatures, the IMD’s Santacruz weather observatory reported a minimum temperature of 13.7 degrees C on Monday, which is 5.6 degrees C below the average.
