Summary Reports

The global land and ocean surface temperature departure from average for March 2019 was the second highest for the month of March in the 140-year NOAA global temperature dataset record, which dates back to 1880. The year-to-date temperature was the third warmest January–March on record. This monthly summary, developed by scientists at NOAA National Centers for Environmental Information, is part of the suite of climate services NOAA provides to government, business, academia and the public to support informed decision-making. March 2019 Temperature The March temperature across global land and ocean surfaces was 1.91°F above the 20th century average of 54.9°F and was the second highest for March in the 1880–2019 record. Only March 2016 was warmer at 2.23°F above average. March 2019 marks the third time in 140 years on record that the March global land and ocean surface temperature departure from average surpassed 1.8°F. March 2016 and 2017 were the other two times. The March 2019 global land and ocean temperature tied with January 2016 as the fifth highest monthly temperature departure from average among all months (1671 months) on record. Record warm March temperatures were present across much of Alaska, northwestern Canada, and across parts of the Barents,
