A little more about July 2021 from NOAA:
"As a whole, the July 2021 global surface temperature was the highest for July since global records began in 1880 at 0.93°C (1.67°F) above the 20th-century average of 15.8°C (60.4°F). This value surpassed the previous record set in 2016 (and subsequently matched in 2019 and 2020) by only 0.01°C (0.02°F). Because July is the warmest month of the year from a climatological perspective, July 2021 was more likely than not the warmest month on record for the globe since 1880. Nine of the 10 warmest Julys have occurred since 2010, with the last seven Julys (2015-2021) being the seven warmest Julys on record. July 1998 is the only July from the 20th century to be among the 10 warmest Julys on record. July 2021 marked the 45th consecutive July and the 439th consecutive month with temperatures, at least nominally, above the 20th-century average."

NASA found it to be second, from Jeff Masters' post:
"NASA rated July 2021 the second warmest July on record, 1.16 degrees Celsius (2.09°F) above the 1880-1920 period, which is their best estimate of preindustrial temperature. The record warmest July in the NASA database is July 2019, which was 0.02 degree Celsius warmer than July 2021. Minor differences occur between the NOAA and NASA numbers because of how they handle data-sparse regions such as the Arctic." |
