Your October weather guide
MildWeather in Paris in October
Paris in October suits a city break with layers and flexible plans, not a trip built around warmth. Average daytime highs are around 16°C, nights fall to about 9°C, and roughly 11 days have rain. That makes walking comfortable when it is dry, but outdoor plans need a wet-weather alternative. Go if you are happy carrying a jacket and adjusting your day; choose a warmer month if lingering outside is the priority.

Mild afternoons, but pack for chilly evenings
The average afternoon is mild enough for walking without summer heat becoming a concern, though sitting outside can feel cool. Pack layers you can remove rather than relying on a light top throughout the day. Warmer spells can reach around 21°C, so a pleasant afternoon is possible, but it should be a bonus rather than the basis of your packing. At the other end, the coldest nights fall to around 4°C or below. A warm outer layer makes sense if you plan to stay out after dark, and closed shoes are a more practical default than sandals. October suits travellers who prefer cooler conditions to heat.
Keep outdoor plans flexible
Rain is the main catch: about 11 rainy days means it deserves space in your plans, without assuming every day will be a washout. Bring a waterproof jacket and shoes you are comfortable wearing on wet pavements; an umbrella is useful too. Sunshine averages about 3.3 hours a day within 10.5 hours of daylight, so do not expect consistently bright afternoons. Put weather-dependent plans into the drier parts of the forecast and leave room to move indoors when rain arrives. Make use of daylight for longer walks rather than leaving them until late, when temperatures also become less comfortable.
