What clothes do I need to prepare for going to five eastern European countries from the end of April to the beginning of May?

The weather in Europe in May and June is complex and changeable, and it is often influenced by sea breeze and multi-ocean airflow, resulting in frequent rain. However, there are also many sunny days in Europe in May and June. Because of the influence of the wind belt, the weather in Europe is a season of alternating sunny days and rainy days. Therefore, tourists had better prepare some raincoats on rainy days, because it is inconvenient to bring umbrellas when the wind is strong.

Traveling to Europe in May and June usually focuses on clothes in winter and autumn, so you need to bring down jackets, but sometimes you need clothes in autumn. Just wear something thin on sunny days and something thick on rainy days, depending on how you wear it, and change clothes according to your body temperature.
