If it is not quite over yet, the year 2022 has been to say the least exceptional in terms of climate.
2022, hottest year
At the national level, “2022 will be the hottest year never recorded on the country since the beginning of the records in 1900. Over the whole year, the temperature exceeds 14.2°C on average in France”, notes Météo France.
2022 thus ranks first among the hottest years, “ahead of 2020, which until now held the record”.
A remarkable drought
Another striking element: the drought, which was remarkable in terms of its duration and extent. “2022 saw the 3e longest period of soil drought in its history. The year was marked by a persistent deficit of precipitation since the end of winter. The exceptionally hot temperatures associated with this lack of rains have aggravated the dryness of the surface soils”.
Toulouse, the most “abnormal” city
At the local level, Toulouse has the particularity of experiencing both strongest temperature anomaly and highest rainfall deficit compared to other cities in France.
In terms of temperatures, it is experiencing a temperature anomaly of +2.1°C. That’s more than in any other city. Nantes (+1.9°C), Bordeaux (+1.8°C), Perpignan (1.8°C) and Strasbourg (+1.8°C) follow behind.
As the Météo France map shows, Toulouse is also the city where the rainfall deficit was the largest (-57%!). Again, it is the only city in France to exceed the 50% deficit threshold, proof that the drought was particularly remarkable in the Pink City. Nice (-47%), Perpignan (-43%) and Bordeaux (-38%) also follow.

Example in Toulouse-Blagnac
At the Toulouse-Blagnac Météo France station, the annual average minimum temperature is thus 11.7°C in 2022 while the average minimum temperature was 9.6°C over the period 1991-2020.
In terms of maximums, the average maximum temperature in 2022 is currently 21.9°C. This is almost two degrees higher than in 2020, which held the record for the highest annual average so far (20.2°C).
As for precipitation, only 56 days of rain were recorded (against 95.8 days on average) for an annual total of precipitation established at 378.7 mm (against 627 mm on average between 1991 and 2020).
