Average global temperatures this June were the fourth warmest since record keeping began in 1880, the World Meteorological Organization (WMO) said on Tuesday.
Citing statistics from the United States National Oceanic and Atmospheric Administration, WMO said the combined average temperature over global land and ocean surfaces was 16.12 degrees Celsius, 0.63 degrees above the 20th century average.
Most areas of the world experienced above-average monthly temperatures, including North America, Eurasia and northern Africa.
However, the monthly temperature during June in Britain was below the 1971-2000 average, making it the coolest June since 1991, said the report.
