The weather in Sweden and September.

Sweden is in northern Europe, and the climate is ok at the end of August. After September, the weather began to get cold and the dark sky began to get longer. It's about 10-23 degrees in Holland, and it's mainly cloudy, but it will be windy after September. The weather in Belgium and the Netherlands is similar, but not so cloudy. By mid-September, the temperature will begin to drop. France is relatively large, I don't know where you are asking. The climate in the southern Mediterranean is good all year round. There are four distinct seasons in the north. I wrote from north to south. The temperature also drops in this order. The farther north, the faster the night. If traveling is the tail of the best period now, the weather will be bad if you don't come again.
