For the globe as a whole, beyond the record streak of 12 months above pre-industrial levels, it was the warmest June in the ERA5 record and the 13th month in a row that was the warmest in the ERA5 record for the respective month of the year.

Although this is unusual, a similar series of monthly global temperature records was seen in 2015–2016. The global-average surface air temperature was 16.66°C; 0.67°C above the 1991–2020 average for the month and 0.14°C above the previous high set in June 2023. The ongoing monthly temperature records are reflected in the global-average temperature for the past 12 months, which is also the highest on record, at 0.76°C above the 1991–2020 average and 1.64°C above the 1850–1900 pre-industrial average. The average sea surface temperature (SST) over 60°S–60°N for June was also the highest on record for the month, at 20.85°C. This is the 15th month in a row that the SST has been the warmest in the ERA5 data record for the respective month of the year. In Europe, the average temperature for June 2024 was 1.57°C above the 1991–2020 average, making the month the joint-second warmest June on record for the region. Temperatures were most above average over southeastern regions and Türkiye, but near or below average over western Europe, Iceland and northwestern Russia.
