September is a beautiful time of the year to visit Paris. The average temperatures range from a high of 70F to a low of 55F. The occasional showers can be expected, and it is wise to always be prepared for the unexpected extreme conditions. The last few years Paris has experienced unusually warm weather. I hope this helps you plan your wardrobe!

The average temperature in Paris in September is 69 degrees. It is typically damp and rainy during that time of year, so I would suggest packing pants, a jacket and an umbrella. However, the temperature is still on the warmer side so I would also bring clothes for both warm and chilly conditions.
