Best time to visit Amsterdam is from mid March to early May, when tulip bulbs flourish, and during the summer, when everybody goes outdoors, filling up the parks, canals and cafes to enjoy the sunshine. Plus, during the summer there is a variety of cultural events and festivals.
The best time in Amsterdam for sightseeing without worries of others getting in the way of your view, is in late autumn and throughout the winter months, Christmas holidays excluded. If this is too cold for you, visit Amsterdam in May, early June, mid September and October, with moderate crowds and more sunny days. The best time for shopping is January and July with huge discounts up to 70%, as all shops want to clear out their inventory.
Don’t miss the chance to visit Amsterdam on King’s Day, the world’s largest street party (takes place on the 27th of April), when everybody is dressed in orange celebrating the birthday of the king, in the streets and canals of the city. There are also large-scale, DJ and artist-driven events at the outskirts of the city, like Kingsland Festival Amsterdam. Book your accommodation well in advance, since Amsterdam is fully booked on that day.
