The year 2022 is the hottest year in France since… 2020, which was already the hottest since 2018. The first six months of 2023 are already well above the average established for the period 1899-2023.
The year 1899 marked a turning point in systematic temperature measurements in the 19th century, with the establishment of an index of average temperatures per month in France. Although the averages are not information in themselves, they provide valuable indications over the long term.

Thus, we went from an annual average of 11.44°C in the 1900s to 11.7°C for the 1950s, then to 12.9°C in the 2000s, and finally to 13.2°C in the 2010s – with an increase that accelerated from the 1980s (12°C) and 1990s (12.6°C). The start of the 2020s does not reverse the trend: for the first four years of the decade, the average annual temperature is already 13.6°C.
Since the 19th century, France has never been so hot as in the 2020s
This graph represents one hundred and twenty-four years of temperature readings in metropolitan France from 1899 to 2023 each month, according to the national thermal indicator of Meteo-France.
Each curve represents a year; it is colored according to its average temperature (in blue when it is cold, in red when it is warmer). The three hottest and three coldest years are listed to the right of the graph.

In mainland France, the four hottest years are 2022 (14.5°C), 2020 (14.1°C), 2018 (13.9°C) and 2014 (13.8°C). Paris, which has some of the oldest temperature readings of French weather stations (from 1873), is experiencing the same level of warming as the rest of France. Without being able to establish this kind of graph for all the cities of France, we thus have reliable data on the capital.
A hundred and fifty years of averages in Paris
This graph represents the temperature readings in Paris (Paris-Montsouris station) from 1873 to 2023 each month, by year.

For the 20th century, temperatures in Paris follow the same trend as in the rest of the country: the older the decade, the colder it is. And as for the hottest years, it is still 2022 and 2020 tied (14.3°C), then 2018 (13.8°C) and 2011 (13.7°C).
