What is the Italian city where you live best from a climatic point of view?
Also this year, according to the 2025 update of the Sole 24 Ore climate index, is Bari to conquer the first place. The Apulian capital is confirmed, for the second consecutive year, such as the territory with the most favorable weather conditions, in front of Barletta-Andria-Trani and Pescaramarking an all southern triumph. Follow Livorno, Enna, Ancona and Trieste.
The study, carried out with the collaboration of the meteorologists of 3bmeteoanalyzed the data of the decade 2014-2024, examining 15 climatic parameters including hours of sunshine, summer breeze, frequency of heat waves, extreme rainfall and tropical nights. The results, developed on a scale from 0 to 1000 points, offer a detailed and updated photograph of climate change at the local level.
Bari, Queen of the Climate (and wellness)
With 744.3 total points, Bari confirms themselves ideal city for those looking for a mild and pleasant climate all year round. “The climate can deeply affect the quality of life”, underline the 3bmeteo experts, and the Apulian capital shows a winning combination of many factors: high sun exposure, good summer ventilation, poor humidity and a few days of extreme heat.
It is no coincidence that the entire Adriatic coast emerges positively in the index: Barletta-Andria-Trani and Pescara, respectively second and third, benefit from similar conditions, while other southern cities such as Enna, Chieti and Catanzaro complete a top 10.
The cities in difficulty: north and internal areas arrange
Not everywhere the climate proved to be equally favorable. At the bottom of the ranking we find Caserta, Terni, Asti, Alessandria and Cremona. The provinces of the North-West, in particular, show critical issues related to the increase in torrid days, stagnant air and the reduction of natural ventilation.
Phenomena such as the increase in tropical nights (night temperatures above 20 ° C) and heat waves have mainly affected Northern Italy. From 2010 to 2024, the average number of tropical nights doubled, going from about 40 to almost 80 per year.
Belluno, although last for sunshine and among the first for cold days, conquers a small positive record: It is the capital with the least number of tropical nights.
Climate change spares no one
The general picture that emerges from the investigation is clear: Italy is becoming increasingly warm and subject to extreme weather phenomena. Between 2010 and 2024, the North recorded an average increase in daytime temperatures by 2.4 ° C. The days with temperatures above 35 ° C increased in all macro -areas: from just 2 days a year in 2010 in the north, it has passed over 11 in 2024.
At the same time, the variability of rainfall is creating new challenges: more periods of drought, alternating with intense rainy events. Cagliari and Agrigento, for example, have seen the periods without rain significantly stretch.
2024: the hottest year ever
2024 has officially consecrated itself as the hottest year in recent history. The summers have become longer and the milder winters: the days of frost in the north dropped from an average of 28 to only 5 per year, with a drastic reduction of snowfalls in the Po Valley.
Between 2010 and 2024, heat waves almost doubled, reaching record numbers especially between August and September. Northern Italy, which once boasted relatively fresh summers, is now increasingly approaching southern climatic models.
As the meteorologist Alessandro Conigliaro recalled: “Climate trends are increasingly conditioned by global variability, but it is locally that can be studied and putting the most effective answers in the field”.
