India's hottest ever reliably recorded temperature stands at around 51°C, set in Phalodi, Rajasthan in 2016. A forecast of 55°C would shatter that record by 4 degrees — an extraordinary margin that no credible meteorological model supports. The India Meteorological Department (IMD) does not issue forecasts in that format; its official extended-range outlooks describe temperatures as "appreciably above normal" using anomaly ranges like +3.1 to +5.0°C above seasonal averages.
The viral message claiming temperatures would reach 45–55°C between April 29 and May 12 was investigated by two independent fact-checking organisations, BOOM and FACTLY, both of whom confirmed it was fabricated. An IMD official from Hyderabad explicitly denied that any such alert was issued by the IMD or the Directorate General of Civil Defence.
During actual severe heatwave events, peak temperatures in the hottest parts of India — such as Rajasthan or Vidarbha — typically range from 45°C to 48°C. While 45°C is a realistic upper bound during extreme events, 55°C has never been recorded anywhere in India and is not considered a plausible near-term threshold by climate scientists or meteorologists.
