Your October weather guide
MildWeather in Milan in October
October is a reasonable time for Milan if you want mild weather for a city break rather than warmth you can rely on. Average daytime highs are 17.2°C, falling to 9.8°C at night, so layers matter more than summer clothes. The catch is rain: about 10 days are wet during the month. Go if you are happy to adjust outdoor plans around showers; choose another month if sunshine and warm evenings are central to your trip.

Nights average 9.8°C; one night in ten drops to 5.5°C or lower, so pack a layer for evenings - it is genuinely cool after dark.

Comfortable for walking, cool after dark
The daytime temperature suits walking around without the strain of summer heat, though you will want a layer when you stop outside. There is some scope for a warmer afternoon: the warmest 10% of days reach 21.5°C or more. That is a possibility, not a sensible basis for your packing. Evenings need more thought, with an average night low of 9.8°C and the coldest 10% of nights falling to 5.5°C or lower. Bring a jumper and a jacket you can wear together rather than relying on a light shirt. October suits travellers who prefer mild days and do not mind wrapping up after dark.
Keep outdoor plans flexible
Rain is the main drawback, so avoid building your whole break around being outdoors. About 10 rainy days means a waterproof jacket, an umbrella and shoes that cope with wet pavements deserve space in your bag. It does not mean every day will be a washout, but a fixed outdoor schedule leaves less room to adapt. Sunshine averages about 4.2 hours a day within 10.7 hours of daylight, so daylight should not be mistaken for clear skies. Keep indoor options available and use brighter spells for longer walks. If your priority is a break built around sunshine, October is a less convincing choice than its mild daytime temperatures might suggest.
