The best month to travel to Europe is April and May which are the spring months and even September and October which are the fall months.
The spring months of April and May and the fall months of September and October are often ideal for pleasant weather and less crowds as well as beautiful scenery.
And the winter months of November through March also offers good budget travel and cozy experiences and the summer months of June through August in Europe also has long and sunny days for beach going and festival activities although there are more crowds and very hot temperatures.
When I visited Europe I preferred the nice spring months of April through May and was in Europe in April on one trip and in May on the other trip.
I also visited Europe before in the summer months and it was a nice visit, but was hot although the beach was nice as well as the festival activities.
If you live winter activities, the winter months can also be a great time to visit Europe, which is also the off season and has lower prices and less visitors.
In the winter months of Europe you can find some nice snowy landscapes, enjoy the Christmas markets in December and also visit the museums and indoor attractions without the long lines.
Winter sports in Europe are also popular in the mountains and you can also see the Northern Lights in Scandinavia during January.
And June through August is the peak season in Europe that has warm, sunny weather and long daylight hours, which is great for music events, beach getaways and festivals.
Although you don't like large crowds the peak season of summer in Europe would not be great for you as there's a huge crowd in Europe in the peak summer months.
