In October, the hottest places in Italy are in the south, particularly in Sicily with an average high temperature of 24°C, followed by Puglia (23°C). Sardinia, Rome and the Amalfi Coast are also warm, with average highs of 22°C. You'll find the most sunshine in the south of Sicily with an average seven hours a day.

The warmest places in Italy during October are found in the far south, specifically on the islands of Sicily and the region of Puglia. In cities like Palermo and Catania, daytime highs often reach 24°C to 26°C (75°F–79°F), and the sea remains warm enough for swimming until mid-month. The "heel of the boot," Puglia (including Bari and Brindisi), also stays quite mild with temperatures hovering around 22°C (72°F). In contrast, Northern Italy starts to feel the autumn chill, with cities like Milan and Venice dropping into the low 60s°F. October in the south is the "perfect window" for travelers who want to avoid the sweltering heat of the Italian summer while still enjoying outdoor dining and coastal walks. It is also the start of the harvest season, meaning you can pair the warm weather with world-class wine festivals and fresh olive oil tastings without the crushing summer crowds.
