The June global land temperature was the seventh highest for June on record at 0.95°C (1.71°F) above the 20th century average of 13.3°C (55.9°F). The seven warmest June global land surface temperatures have all occurred within the past decade. The warmth was fairly evenly distributed between the Northern and Southern Hemispheres, with the Northern Hemisphere land-surface temperature sixth highest on record and the Southern Hemisphere land-surface temperature fifth highest. As indicated by the Land & Ocean Percentiles Map above, record warmth was present across part of southern Greenland, parts of northern South America, areas in eastern and central Africa, and sections of southern and southeastern Asia. A few areas in North America, Far East Russia, and small parts of central and eastern Europe were cooler or much cooler than average.
