Copenhagen weather by month

When to go to Copenhagen

For beach weather, look at months where the daytime average clears 25°C and rainy days stay low: none reach a 25°C average here, so Copenhagen suits city breaks and walking more than beach holidays; the warmest is July. August is the wettest month (76 mm, about 13 rainy days) and April the driest (41 mm).

Getting there

A direct flight from London Gatwick to Copenhagen Kastrup Airport (CPH, 9 km from Copenhagen) takes roughly 2 h - short-haul (up to 4.5 h) by UK standards. Time-zone: Europe/Copenhagen.

Records and extremes, 1991-2020

The hottest day recorded in Copenhagen between 1991 and 2020 reached 29.6°C on 10 August 1992; the coldest fell to -18.0°C on 4 January 1996. In July one day in ten tops 25.2°C, but 30°C days are rare; in January one night in ten drops to -5.5°C or below. The wettest single month of the period was July 2007 with 181 mm, against a July average of 72 mm.

Spring: brighter days, but keep your layers

Spring becomes much more comfortable as it progresses. March averages 6°C by day and 1°C at night, so a warm coat still earns its place in your bag. April lifts daytime temperatures to 11°C and brings 6 hours of sunshine, making it a better fit for spending longer outdoors, provided you dress warmly. It is also the driest month, though its 10 rain days mean waterproof clothing remains useful. May is the strongest spring option for milder weather: afternoons average 15°C, with 7 hours of sunshine. Nights still fall to 8°C, so do not mistake brighter days for warm evenings.

Summer: the best warmth, not a dry-weather guarantee

Summer offers Copenhagen's most comfortable conditions for days spent outside. June averages 18°C by day, rising to 21°C in July before easing to 20°C in August. July is the best choice if warmth matters most, but none of these months calls for packing only hot-weather clothes. Average nights range from 12°C in June to 15°C in August, making a jumper or light jacket useful after dark. June and July both average 7 hours of sunshine, compared with 6 in August. The main catch is rain: each summer month averages 12 rain days, and August is the wettest month. Keep outdoor plans flexible rather than expecting uninterrupted sunshine.

Autumn and winter: cooling quickly, with little sunshine

September is the gentlest autumn choice, with daytime temperatures averaging 17°C and nights 12°C. By October, afternoons fall to 12°C and sunshine drops to 3 hours, so longer outdoor days need warmer clothing and a rain backup. November feels much less inviting for a weather-led trip, averaging 7°C by day and 2 hours of sunshine. Winter stays cold: December averages 4°C by day, while January and February reach just 3°C. February nights average -1°C, so pack a warm coat and layers rather than relying on a light jacket. These months suit travellers content with shorter spells outdoors and regular indoor breaks. Rain remains a consideration, and the limited sunshine makes flexibility more useful than an outdoor-heavy schedule.
