What clothes are suitable for traveling to Europe in June?

Italy and southern France may be a little hotter, but the temperature is lower than that in China, so it should be relatively comfortable at this stage. On the whole, except for Spain, the rest of Europe is ok. Does Switzerland go to Snow Mountain? Pay attention to cold protection when going up the mountain. For the specific weather forecast, you can refer to Accuweather.com, and you can provide the forecast of 14-2 1 day, but personally, it can only be used for reference, which is not very accurate.
