From NOAA’s Global Climate Report – August 2021:
The August 2021 global surface temperature was 0.90°C (1.62°F) above the 20th century average of 15.6°C (60.1°F). This was the sixth warmest August on record. Nine of the 10 warmest Augusts have occurred since 2009. August of 1998 still ranks among the 10 warmest on record. August 2021 was also the 45th consecutive August and the 440th consecutive month with temperatures, at least nominally, above the 20th century average.
And for land only:
Averaged as a whole, the global land-only surface had a near-record high August temperature at 1.34°C (2.41°F) above average, which is only 0.04°C (0.07°F) less than the record-warm August set in 2016. This was mainly driven by the very warm land-only surface temperatures across the Northern Hemisphere, which had its warmest August on record at +1.44°C (+2.59°F). This value surpassed the previous record set in 2016 by 0.04°C (0.07°F).
