How to prepare and pay attention to the weather when traveling to Europe from May 24th to June 5th?

The continental Europe has a maritime climate, and the weather is much more comfortable than ours. The temperature is generally lower than here, especially in southern Germany (around Munich) and Austria, where the altitude is high (on both sides of the Alps) and the temperature is lower. The temperature in the Netherlands and Switzerland is also low, while the temperature in southern France is high.

The lowest temperature in Europe during this period is generally below 10 degrees, so you need to bring a sweater. If you go to the Alps, it will be colder.

Don't forget the live socket converter, German standard, French standard and Italian standard, otherwise it won't work there.

Prepare some small change with low face value. Many toilets in Europe charge, not change.
