The Netherlands enjoys a temperate climate, with relatively mild summers and moderately cold winters. The best time to visit, if you'd like to see the country's tulips in bloom, is roughly mid-March to mid-May. Generally speaking, temperatures rise the further south you go. This is offset by the prevailing westerlies that sweep in from the North Sea, making the wetter coastal provinces both warmer in winter and colder in summer than the eastern provinces, where the more severe climate of continental Europe has an influence. As far as rain is concerned, be prepared for it at any time of year.
