Weakened morale, essential umbrella and vitamin D to compensate for the lack of sun. The year 2024 seems to be breaking records for rain with absent sunshine. And particularly here in Île-de-France. Do Météo France analyzes confirm our feelings? We explain the supporting figures to you.

“In the first semester, it rained all the time, it was very unusual. We talked about it among ourselves. What I remember is that all outdoor activities fell through”testifies this Parisian fan of cycling outings.
This year 2024, the sky has fallen on our heads in Île-de-France, we could also say by consulting the latest annual rainfall report drawn up by Météo France. “The year 2024 was remarkable for its excess rainfall, particularly in the region, confirms Patrick Galois, forecaster at Météo France.
In Île-de-France, the cumulative precipitation was 36% higher than seasonal norms (1991-2021). A deluge of rain observed especially in Val-d'Oise, Yvelines, Essonne and particularly in Paris.
We have never experienced so much rain in the capital since 1876, since the commissioning of the Paris-Montsouris rainfall measuring station. The record recorded in 2000 (900.8 mm) was narrowly beaten.
It came down to a few drops, less than a millimeter. There is an excess of rain of around 42% over the year for Paris.

In the region, from the beginning of 2024, curtains of rain followed one another. “We had very rainy months in autumn. In September for example, around 115 mm of rain, two and a half times normal.” The biggest deviations from seasonal norms were noted in the last months of the year as can be seen in the graph below.

At the national level, 2024 is, according to Météo France, among the ten rainiest years. A year marked by floods and numerous floods. “There are alternations of anticyclones and depressions and sometimes the depression regimes prevail during a sequence which can be several months, sometimes even several years and sometimes, it is the opposite. explains Patrick Galois.
“The low pressure sequence which set in in the fall of 2023 continued for a good part of 2024. This time it is a natural variation in the climate. It's not necessarily linked to human influence.”he specifies.
Above-normal precipitation, insufficient sunshine, rising temperatures, here in three tables, what to remember from the year 2024.
-“I have the impression that for four months, we have had very, very little sunshine and it has been the same thing since the beginning of the year,” testifies this disgruntled passerby.
Feeling confirmed by Météo France which sums up the past year as follows: “2024 is on average the least sunny year that France has experienced in almost thirty years..
Nationally, the sunshine deficit reaches 10% compared to normal. In Île-de-France, it is even more accentuated: between 12 and 13% deficit, notes Patrick Galois. That is almost 200 fewer hours of sunshine in the region compared to annual averages.
2024 is on average the least sunny year that France has experienced in almost thirty years.

With the exception of August, all months of the year were short of light compared to seasonal standards. With more than 45 fewer hours of sunshine, February 2024 was undoubtedly the darkest time of the year in Île-de-France. Overall, “o“We can say that in Paris, 2024 is the least sunny year of the 21st century.” adds the meteorologist.

“It’s cold, but everything is normal!”affirms this pedestrian without batting an eyelid. The winters follow one another and are almost the same. According to Météo France, “2024 is one of the five hottest years in France”.
“A rather mild year in Île-de-France”, euphemizes Patrick Galois, in any case less hot than 2022, 2023, 2020 and 2018. Last year in the region, the temperature rose by 0.7 to 0.9 degrees. In winter 2024, especially in February, “We were almost 4 degrees above normal”assesses the forecaster.

Classified in the hottest years, the year 2024 is not necessarily a year “outstanding”, according to Patrick Galois. The observed rise in temperatures, however, is part of a trend. Average temperatures in Paris could reach those of Montpellier today by the end of the century, according to a study by Meteo-France and the National Center for Meteorological Research, published last month.
“The average annual temperature of 2024 will be exceeded in a France at +2.7°C by 2050 (more than one year in two) and almost systematically in a France at +4°C by 2100”observes Météo France in its climate report for the year 2024.
“When we talk about climate warming, these are not records, they are temperatures overall which are milder whatever the weather scenario. That is to say, when it is cold, it is less cold that before and when it's hot, it's warmer And this is a global trend that we see every day of the year. explains Patrick Galois.
Here is a summary of what you need to remember: record rains and a sun at half-mast, 2024 is a year under water and in the gray in Île-de-France.
