I will go to France, Switzerland and Italy on September 25th,1what should I wear when I come back on October 6th?

France and Switzerland have been hovering around 10 degrees in the morning, unless there is a special temperature increase at the end of September. At noon, if the sun is shining, it will still be around 23-26 degrees (26 degrees is the temperature in the south of France, and it peaks at 24 degrees at the junction of France and Switzerland at most). When it is cloudy and windy, the temperature will drop by about 15 degrees. It should be warmer near Sicily, Italy (but I don't know the exact temperature).

It is recommended to bring a thick coat. Girls must bring a pair of warm pants, not a skirt.

I am at the junction of France and Switzerland. I went to the suburban river last night and came back after 7 o'clock in the evening. I wore a T-shirt and a knee-length skirt when I went out, and I specially brought a sweater. I started to feel cold after sunset 1 hour, and I was already shaking when I left at 7 o'clock. Be sure to wear pants at night, preferably a warm and thick coat. Get ready.
