Amsterdam enjoys a moderate temperate climate, with the weather patterns being strongly influenced by Amsterdam's proximity to the North Sea to the west and its prevailing north-western winds and gales. Winter temperatures are mild: on average above freezing, although frosts are not uncommon during spells of easternly or northeasternly winds blowing in from the inner European continent. Summers are warm but rarely hot. Days with measurable precipitation are common, but still Amsterdam averages less than 760 mm of precipitation annually. Most of it falls as protracted drizzle or light rain. But the occasional Western storm may bring a lot of water at once, and all of it has to be pumped out to higher ground and to the seas around the city. These bodies of water make cloudy and damp days common, particularly in cooler months, October through March.
