Why is Florence mild in December?
In December, the Azores High weakens and retreats southward, allowing Atlantic storm tracks to cross the Mediterranean and bring the city its seasonal rainfall. Temperatures average 15°C during the day and drop to 6°C at night as cold continental air occasionally pushes in from the north. This is the rainy season that keeps the region's landscape green through spring. Climate data: Open-Meteo ERA5 (1991–2020).
