The majority of the world’s land surface had warmer to much-warmer-than-average temperatures during June 2016, with the largest temperature departures observed across much of north-central Russia, the Russian Far East, and northern Australia where temperature departures were 3.0°C or higher.
Record warmth was sporadically across parts of the southwestern contiguous U.S., southern Mexico, northeastern Brazil, northeastern and southwestern Africa, the Middle East, northern Australia, and Indonesia. The only land area with cooler-than-average conditions during June 2016, according to the percentiles map, was central and southern South America. No land areas had a record cold temperature during June 2016. According to NCEI’s Global Regional Analysis, five of six continents had at least a top five warm June, with North America observing a record high average temperature for June.
Averaged as a whole, the global temperature across land surfaces for June 2016 was 1.24°C above the 20th century average—tying with 2015 as the highest June temperature in the 1880–2016 record. June 2016 marks the 34th consecutive June with temperatures at least nominally above average. The last time global land surface temperatures were below average in June was in 1982 (-0.05°C).
The combined average temperature over global land and ocean surfaces for June was 0.9°C above the 20th Century average of 15.5°C, the NOAA said in its monthly report.
