Average daily temperature reaches 17.5 °C

New record daily global average temperature reached in July 2024

The Earth has just experienced its warmest day in recent history, according to the Copernicus Climate Change Service (C3S) data. On 22 July 2024, the daily global average temperature reached a new record high in the ERA5 dataset, at 17.15°C. This exceeds the previous records of 17.09°C, set just one day before on 21 July 2024, and 17.08°C, set a year earlier on 6 July 2023.

Based on preliminary data released by C3S on 24 July, Monday 22 July was the hottest day in the ERA5 dataset, which begins in 1940.

While the temperature on 21 July 2024 (17.09ºC) was almost indistinguishable from the previous record of 17.08ºC reached on 6 July 2023, the difference between these and the new record temperature (17.15°C) reached on 22 July is larger than typical differences in day-to-day variations among alternative datasets.

What really stands out is also the difference between the temperatures since July 2023 and all previous years. The data can be explored in Climate Pulse, the C3S application that provides historical and near-real-time temperature data from the ERA5 reanalysis dataset.
