The world just sweltered through its hottest June in the 174-year global climate record.

The June global surface temperature was 1.05°C above the 20th-century average of 15.5°C, making it the warmest June on record. This marked the first time a June temperature exceeded 1°C above the long-term average.

June 2023 was 0.13°C warmer than the previous June record from 2020, but 0.29°C cooler than the all-time highest monthly temperature anomaly on record (March 2016).

June 2023 marked the 47th consecutive June and the 532nd consecutive month with temperatures at least nominally above the 20th-century average.

Additionally, Earth’s ocean surface temperature anomaly, which indicates how much warmer or cooler temperatures are from the long-term average, were the highest ever recorded and the sea ice coverage hit a record low, according to scientists from NOAA’s National Centers for Environmental Information.
