Denmark Geography & Climate

Denmark proper covers about 43,000 square kilometres — the Jutland peninsula extending north from Germany, plus some 400 named islands, of which about seventy are inhabited.

Very flat

The highest natural point, Mollehoj in eastern Jutland, is 171 metres, and the average elevation is around thirty. The landscape is the work of ice: moraine ridges, meltwater valleys and, in western Jutland, the flat outwash plains left beyond the last glaciation’s limit. This is why the country is cycled rather than climbed.

The islands

Zealand holds Copenhagen and is the largest; Funen sits between it and Jutland; Lolland, Falster and Mon lie to the south. Bornholm is the outlier, far out in the Baltic nearer Sweden and Poland, and is granite rather than glacial till, which is why it looks nothing like the rest of the country.

Two seas

The North Sea coast of west Jutland is dunes, sandbars and wind; the Baltic side is calmer, with fjords and beech woods. At Skagen the two meet, and on a calm day you can watch the currents collide.

The Wadden Sea

The tidal flats along the south-west coast are UNESCO-listed, shared with Germany and the Netherlands, and are a staging ground for millions of migratory birds — the sort sol, the murmuration of starlings above the marshes in spring and autumn, happens here.

Land taken back from the sea

A striking amount of Denmark is engineered. The Lammefjord in Zealand was drained in the nineteenth century and its floor now lies about seven metres below sea level, the lowest ground in the country and famous for its carrots; the marshes behind the west Jutland dykes are similar work. A flat country facing two seas has spent centuries deciding exactly where its own coastline should be.

The realm

The Kingdom also includes the self-governing Faroe Islands and Greenland, which is what makes it territorially one of the larger states on earth.

Denmark has a temperate maritime climate, moderated by the sea on every side and by the North Atlantic Drift, which makes it much milder than its latitude — the same as southern Alaska — would suggest.

Summer

June to August averages 20 to 22°C, occasionally reaching the high twenties, with long evenings; at midsummer it is light until nearly eleven and never fully dark. Rain arrives in showers rather than in spells, and a warm day can turn in an hour.

Winter

December to February sits around 0 to 4°C — wet and grey more than cold, with snow that seldom lies long. The real difficulty is the darkness: sunrise near nine and sunset near four in late December, with heavy cloud between. This is the climatic fact that explains candles, the Christmas markets and hygge.

Wind

Denmark is one of the windiest countries in Europe, exposed on a flat peninsula between two seas, and the westerlies are near-constant. It is why the country built a wind industry that now supplies a large share of its electricity, and why a still day on the west coast is noteworthy. Windchill matters more than the thermometer here.

Rain

Around 700 millimetres a year, distributed across every month with a slight autumn peak. There is no dry season; bring a waterproof in July.

The sea

Around 17 to 20°C in August, which Danes regard as swimming weather, and cold enough the rest of the year that the winter bathing clubs are a distinct subculture.
