Mean measurements by the KNMI-weather station in De Bilt between 1971 and 2000:

The Netherlands have a temperate maritime climate influenced by the North Sea and Atlantic Ocean, with cool summers and moderate winters. Daytime temperatures varies from 2°C-6°C in the winter and 17°C-20°C in the summer.

Since the country is small there is little variation in climate from region to region, although the marine influences are less inland. Rainfall is distributed throughout the year with a dryer period from April to September.

Especially in fall and winter strong atlantic low-pressure systems can bring gales and uncomfortable weather. Sometimes easterly winds can cause a more continental type of weather, warm and dry in the summer, but cold and clear in the winter with temperatures sometimes far below zero. Holland is a flat country and has often breezy conditions, although more in the winter than in the summer, and more among the coastal areas than inland.

Required clothing:
Lightweights with rainwear for summer, waterproof and warmer clothing for winter.An umbrella and a sweater are necessary almost any time of year.

Koeppen-Geiger classification:
The climate of The Netherlands can be classified as Cfb Climate; a warm temperated humid climate with the warmest month lower than 22°C over average and four or more months above 10°C over average.
