Denmark has a predominantly humid continental climate (Köppen climate classification Dfb). About one-fifth of the southern Jutland Peninsula displays a temperate oceanic climate (Köppen Cfb). Denmark is a Nordic and Scandinavian country in Northern Europe, to the southwest of Sweden and south of Norway. The only land borders are with Germany in the south. The North and Baltic Seas share maritime borders with the country, along with its numerous offshore islands. The northern temperate latitudes and proximity to vast bodies of water mainly influence the climate.

Denmark lies in the temperate zone between 54°N and 57°N. The Nordic country consists of the Jutland Peninsula and more than 443 named islands. The landscape is mostly flat, with an average elevation of 31 meters above sea level. Mollehoj in the Ejerbjerge hills is the highest natural point in Denmark at a mere altitude of 170 meters. Rolling plains form a chunk of the terrain, along with sandy coastlines and large dunes. Odense, Gudena, Susa, Skerjn, and Vida are important rivers that flow across the country. The largest lake is Lake Arreso, with an area of 15.39 square miles. The area of inland water is 270 square miles. The coastline is 1057 miles long, excluding the shorelines of the numerous offshore islands. Any location in the country is at a maximum distance of 32 miles from the coast. The Kingdom of Denmark includes Greenland and Faroe Islands.

The climate of Denmark is mild relative to its northerly location due to the influence of ocean waters. Cloudy skies, humidity, wind, and rain are standard features. The western Jutland coasts have milder weather than the rest of the country. Summers are pleasantly warm but frequently wet. The average temperatures are in the warm 12.8°C (55°F) to 22.2°C (72°F) range, and the daylight lasts for more than 15 hours. Temperatures rarely cross 30°C (86°F) on hot days due to the influence of the southern currents. Nights are cool to mild, even at the peak of the summer. Winters are cold and dark, with poor sunshine. The Siberian High brings eastern currents that push the temperatures down to -20°C (-4°F) in worst conditions. Night temperatures remain below freezing, and precipitation is moderate but frequent. Moderate snowfall occurs during the winter. Spring is cold until May when the average temperatures register in the 7.8°C (46°F) to 16.1°C (61°F) zone. Autumn is comfortable in September but becomes windy and rainy in the second half. November is cold, dull, and rainy.

The annual rainfall in Denmark is in the moderate range of 508mm (20") to 812.8mm (32") and occurs evenly throughout the year. June to August is the peak precipitation period, while the driest period is in March and April. Western Jutland receives 800.1mm (31.5") of rain annually, which drops to 635mm (25") in the extreme north, and 508mm (20") in the east. The period from November to mid-April accounts for 20 days to 25 days of moderate snowfall. Atlantic depressions occur throughout the year. The annual sunshine in Denmark is weak and registers between 1600 hours and 1800 hours. Most of the bright days are between late spring and early autumn.

Winter storms are standard, especially during December and January. Cyclone Anatol cost Denmark 20 fatalities and US$ 3 billion in December 1999. Cyclone Xaver, a force 12 winter storm in 2013, brought heavy rain, snowfall, and strong winds. Tidal surge during storms is responsible for coastal flooding.
