Sorted by popularity:

What's the Weather Like in Copenhagen in September

As the seasons change with September so do the temperatures. After experiencing the two warmest months of the year in July and August, temperatures drop off sharply as autumn is ushered in. While conditions may still be pleasant for the early part of the month, the end will require heavier jackets. As a result, visitors will need to check an extended forecast before leaving home in order to make sure that they are packed appropriately.

Average Sea Temperature and Sunshine Hours

Despite the fact that temperatures are falling, there is still a little time left to hit the beach. In fact, this will be the last opportunity until next summer for beach goers to dip their toes in the water before it gets too cold. The average water temperature for this time of the year will be 16°C (61°F). Visitors can also enjoy one more month with plenty of sun as the region will average 10 hours of sunshine per day over the 30-day period.


On land, temperatures begin to fall off sharply with an average daily temperatures of 14°C (57°F). In fact, the average afternoon highs have dropped considerably from the previous month and will now only climb to 17°C (63°F). While overnight lows are not cold enough to require a full heavy winter weather outfit, visitors will need to bring a coat with some weight to it to fight off the evening and early morning chill. The average overnight low for this time of the year is a cool 10°C (50°F).


Rainfall rates remain high with an average of 60mm of precipitation expected over the course of the month. However, this precipitation will be in the liquid form as freezing temperatures are still a few months away. This rain will also fall over a period of 15 days making raingear a necessity for visiting during this time.

Hotel Alexandra

Step back in time with the retro feel of Hotel Alexandra. Just steps away from some of the best shopping, hottest restaurants and best sights in Copenhagen, the hotel offers 61 rooms decorated with the style of the '50s and 60s, paying homage to famous Danish furniture designers such as Arne Jacobsen and Hans Wegner, who earned the country recognition in the eyes of the world for fashion and design.

Things to do in Copenhagen in September

King's Garden

September makes a good time to enjoy the last vestiges of warm weather before autumn truly sets in, and it's worth exploring the city's abundant parks and gardens. Located in the centre of the city is the King's Garden (Kongens Have), which surrounds the Rosenborg Palace and qualifies as the oldest royal garden in Denmark, dating back to the 1600s. Visited by a staggering 2.5 million people each year, the gardens are noted for their impressive flowerbeds and their statue of Hans Christian Andersen, one of Denmark's biggest exports.

Designmuseum Danmark

Despite its small size and population, Denmark is rightly famous for being one of the design hubs of the world and Designmuseum Danmark does justice to the country's reputation as a haven for fashion and innovation. Housed in a building which was once the country's first public hospital, the museum showcases displays from the Middle Ages right up to the present day. In addition to its permanent collection, there are also regular exhibits taking place throughout the year. 

Charlottenborg Palace

Art lovers are really spoiled for choice in Copenhagen, as the city packs in a disproportionate number of prominent galleries and museums. Charlottenborg is one such gallery, which is an extension to the original Charlottenborg Palace and has been greeting the public since 1883 as a place to promote local and international talent. A range of exhibits takes place here year-round, and there's also a calm courtyard space which is ideal for picnicking families. Entry is free upon presentation of a Copenhagen Card. 

Royal Library

An architectural gem of Copenhagen is the Royal Library, which proudly sits on the edge of Copenhagen Harbour. Divided by two halves, the original component was built in the 1600s, while the newer half opened in 1999 and is colloquially known as the 'Black Diamond'. The building is open to the public, although all materials need to be reserved ahead of time. 

Golden Days of Copenhagen

Copenhagen celebrates music, film, arts and theatre in September through the many festivals lined up for this month.  The grandest is the Golden Days of Copenhagen which commemorates 19th century as the period of rapid advancement of the country. The festival is held for three weeks and features theatre and ballet shows, poetry readings, concerts and art exhibits all focusing on Denmark's Golden Age (1800-50). 


Film lovers will enjoy CPH PIX, which takes place at the end of September each year in the city to promote up-and-coming talent from Denmark and around the world. Year in, year out, the festival invites visitors of all ages to showcase up to 150 of the latest releases from around the world. Denmark is proud of its movie culture and film-making tradition, which has turned out arthouse talent such as Lars Von Trier and Thomas Vinterberg under the Dogme 95 movement. 

Copenhagen Blues Festival

On the music front, September jump-starts the annual Copenhagen Blues Festival with blues acts performing all over the city. International and homegrown talents come together for five days in September to make Copenhagen a blues haven.
