Per NOAA's report :

The July temperature across global land and ocean surfaces was 1.57°F above the 20th century average of 60.4°F. This was the highest for July in the 1880–2016 record, surpassing the previous record set in 2015 by 0.11°F, the previous record holder for the warmest month on record. July 2016 marks the 40th consecutive July with temperatures at least nominally above the 20th century average.

The July globally averaged land surface temperature was 1.98°F above the 20th century average of 57.8°F. This value tied with 1998 as the highest July global land temperature in the 1880–2016 record. This was the 24th consecutive July with global land temperatures above the 20th century average, with July 1992 being the last time July global land temperatures were below average.

The July globally averaged sea surface temperature was 1.42°F above the 20th century monthly average of 61.5°F—the highest global ocean temperature for July in the 1880–2016 record, surpassing the previous record set in 2015 by 0.07°F. July 2016 marks the 40th consecutive July with global ocean temperatures at least nominally above the 20th century average.
