Amsterdam, the capital of Holland, is a city that needs no introduction. It enjoys a climate warmer than its sister-cities due to the Gulf Stream (the global air current which draws tropical air from the Caribbean area up to the north-west of Europe). It is a perfect place to go to all year round with events to keep you occupied any month. June-July & early August is when the peak season starts for people who prefer to be in a reasonably pleasant climate. Whereas, winter in Amsterdam is not frozen but extremely cold, so it is better to have things that will keep you warm.
