The weather in France in September

The weather in Italy, southern Europe and the Mediterranean is still very pleasant in the middle and late September. It looks like 25-30 degrees during the day, and it should basically be sunny. In high-latitude areas of France, such as Paris (Paris is actually the same latitude as Harbin), the weather has been average since September, with crisp autumn and a temperature of only a dozen degrees. There are many mountains in Switzerland, and the temperature difference between day and night is large. France and Switzerland need to prepare autumn clothes in September. When traveling, long-sleeved sweaters and light coats are good choices.
