Why does the Netherlands have mild winters and cool summers?

The Netherlands experiences a temperate climate characterized by mild winters and cool summers primarily due to the moderating influence of the sea and the Gulf Stream system.1

The country’s climate is heavily influenced by prevailing westerly and southerly winds that carry maritime air across the land. This air is warmed by the North Atlantic Current—an extension of the Gulf Stream—which transports heat from tropical waters toward the high latitudes of northwestern Europe. This poleward transfer of heat, facilitated by thermohaline circulation, helps maintain milder temperatures than would otherwise be expected for the region's latitude.123

Additionally, the Netherlands' position between high-pressure air masses over the Azores and low-pressure regions near Iceland creates a constant interaction between warm and polar air masses, contributing to the country's unsettled but temperate weather patterns.1
