An unmistakable warming trend continued in August 2021, which was the sixth warmest August on record, according to US meteorological agency NOAA.

Details of global surface temperatures are contained in a monthly global climate report issued overnight by NOAA National Centers for Environmental Information at http://www.ncei.noaa.gov.

key excerpts from the report follow.

”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.”

“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).

“While the Southern Hemisphere as a whole had its fourth warmest August on record, the Southern Hemisphere ocean-only surface temperature tied with 2018 and 2019 as the second highest on record at 0.61°C (1.10°F) above average. Only August of 2016 had a warmer ocean-only surface temperature for the Southern Hemisphere.

”In Oceania, Australia's mean temperature for August was the sixth highest in the nation's 112-year record at 1.38°C (2.48°F) above the 1961–1990 average. Regionally, Queensland had a near-record warm August with a temperature departure of +2.13°C (+3.83°F), which was 1.22°C (2.20°F) cooler than the record-warm August set in 2009. Meanwhile, New South Wales, Victoria, and Tasmania had a top 10 warm August. New Zealand's August temperature was 0.9°C (1.6°F) above the 1981–2010 average and tied as the ninth warmest August on record.”

NOAA’s monthly climate report for August also analyzed temperatures for the June to August period and for January-August. the analysis is presented in both text and graphical form.

of particular note are record land-only surface temperatures June-August.

NOAA:

”The June–August seasonal global surface temperature departure of +0.90°C (+1.62°F) was the fourth highest for the three-month season on record. Only June–August of 2016, 2019, and 2020 were warmer.

”During the three-month period, temperatures were much above average across much of the land surfaces across the globe, resulting in the record-warm global land-only surface temperature for June–August at 1.38°C (2.48°F) above average. This value exceeded the previous record set in 2016 by 0.13°C (0.23°F).”

“The June–August period is defined as the Northern Hemisphere's meteorological summer and the Southern Hemisphere's meteorological winter. The Northern Hemisphere's summer temperature departure of +1.14°C (+2.05°F) tied with 2019 as the second warmest summer on record, only behind summer of 2020 by 0.04°C (0.07°F). The Northern Hemisphere land-only summer temperature was the highest on record, besting the now-second highest set in 2016 by 0.20°C (0.36°F).

” Meanwhile, the Southern Hemisphere had its fifth warmest winter (tied with 1998) on record.

“In Oceania, Australia had its fourth warmest winter in the nation's 112-year record with a national mean temperature of 1.18°C (2.12°F) above the 1961–1990 average.

” Meanwhile, winter 2021 marked New Zealand's second consecutive winter that a new winter temperature record was set the nation's winter temperature was 1.3°C (2.3°F) above average — the warmest winter on record. The previous record warm winter was set last year (2020), marking only the second time since New Zealand's temperature records began in which a new winter temperature record was set back-to-back. The last time it happened was in 1970 and 1971.

“The January–August 2021 global surface temperature was the sixth warm such period, with a temperature departure of 0.82°C (1.48°F) above average. The year 2021 is very likely to rank among the ten warmest years on record, with less than 2% chance to rank among the five warmest years on record, according to a statistical analysis done by NCEI.

“no land or ocean areas had a record-cold January–August temperature.”
