A NOAA news report, Global Climate Report – March 2017 Monthly temperature anomalies versus El Niño, provides us with the graph here of monthly temperature colored coded by ENSO events. The report notes that
March 2017 marks the first time since April 2016 that the global land and ocean temperature departure from average is greater than 1.0°C (1.8°F).
This is also the first time a monthly temperature departure from average surpasses 1.0°C (1.8°F) in the absence of an El Niño episode in the tropical Pacific Ocean.
March 2017 tied with January 2016 as the fifth highest monthly global land and ocean temperature departure from average on record (1,647 monthly records).
