Copenhagen Travel Guide
When to Visit Copenhagen
Copenhagen month by month: long summer days and harbour swimming, Halloween and Christmas in Tivoli, the 2026 Christmas market dates, winter hygge and the best time for your trip.
Copenhagen changes dramatically with the seasons, from the endless light of June, when the city lives outdoors and swims in the harbour, to the short, dark days of December, when candles, lights and Christmas markets fill the streets. There is no bad time to visit, but the experience is very different, and some of the city's biggest attractions, above all Tivoli, open only at certain times of year. Here is how to choose.
Summer: June to August. Summer is the high season and, for many, the best time to visit. The days are very long, with light until late evening around midsummer, the cafes and restaurants move outdoors, the parks fill with picnics, and Copenhageners swim in the harbour at the public harbour baths. Tivoli is open in its summer season, with flowers, open-air concerts and long evenings, and the city hosts major festivals, including the Copenhagen Jazz Festival in July, and the Roskilde Festival takes place nearby around the turn of June and July. The weather is mild rather than hot, and rain is always possible. The downsides are crowds at the main sights, the highest hotel prices of the year, and busy canal tours, so book ahead.
Spring and early autumn: April, May and September. The shoulder seasons are excellent for visiting: the weather is often fresh and sunny, the crowds are smaller, and hotel prices are lower than in summer. Tivoli's summer season usually opens in spring, the cherry trees and parks blossom in April and May, and the Louisiana museum's sculpture park is lovely in the soft light. September keeps much of the summer atmosphere, with the harbour still lively and the restaurants buzzing.
Autumn and Halloween: October and early November. In October, the leaves turn in the parks and around the Lakes, and Tivoli reopens for Halloween, filling the gardens with pumpkins, witches and spooky decorations; in 2026, the Halloween season opened on 2 October and runs into the first days of November. It is a very popular time for families during the autumn school holiday. The weather becomes cooler and wetter, and the days shorten quickly. Note that Tivoli closes between the end of Halloween and the start of the Christmas season.
Christmas: mid-November to early January. Christmas is the most magical time to visit Copenhagen. Christmas in Tivoli runs from 13 November 2026 to 3 January 2027, with a million lights, decorated trees, a Christmas market and glogg, and the rides still running; the Nutcracker plays the Tivoli Concert Hall from 26 November to 20 December 2026. The city's other Christmas markets in 2026 include the market on Nytorv and Gammeltorv, from 6 November to 21 December; the market on Hojbro Plads, from 14 November to 20 December; the market on City Hall Square, from 11 to 20 December; and the Nyhavn market on the quay in December, whose exact dates are announced late in the year. Kronborg Castle hosts a Christmas market at weekends, and the Grey Hall in Christiania holds a much-loved crafts and design market in December. Check the official listings before you travel, as dates can change. The days are short and dark, and the weather is cold, damp and windy, but the lights, candles and cosy cafes make it the season of hygge.
New Year's Eve. Copenhagen celebrates New Year's Eve with enthusiasm and a great many fireworks, set off by people all over the city at midnight. Crowds gather at City Hall Square for the bells of the City Hall clock, and Tivoli closes its Christmas season with a New Year's Eve dinner and a midnight fireworks display. Book hotels and dinners well in advance.
Winter: January to March. After the Christmas season, Copenhagen is at its quietest, coldest and cheapest. Tivoli is closed, the days are short, and some attractions keep reduced hours; Kronborg, for example, closes on Mondays in winter. But the museums, castles and restaurants are open, there are fewer visitors, hotel prices are at their lowest, and the city's cosy cafes, candlelit bars and saunas, including floating saunas on the harbour, are at their best. The Round Tower's observatory opens for stargazing on winter evenings. It is a good time for a city break focused on art, design and food.
What to pack. Whatever the season, bring layers, a waterproof jacket and comfortable walking shoes, as the weather changes quickly and you will walk a lot. In winter, add a warm coat, hat, gloves and scarf, as the wind off the water is cold. In summer, bring a swimsuit for the harbour baths and a light sweater for the evenings.
The verdict. For long days, outdoor life and Tivoli in full summer swing, come in June, July or August, and book early. For good weather, fewer crowds and lower prices, come in May or September. For Christmas magic, come between mid-November and the end of December, when Tivoli and the markets are open. For low prices and a quiet, cultural trip, come in January to March. Whatever you choose, stay somewhere cosy: in winter, Nimb's fireplaces and Manon Les Suites' indoor pool are particularly welcome.
Events to plan around. Beyond Tivoli and Christmas, a few annual events shape the calendar. Culture Night in October opens museums, churches and institutions across the city late into the evening. The Copenhagen Jazz Festival in July fills cafes, squares and clubs with concerts, many of them free. Summer brings outdoor concerts in the parks and open-air cinema, and the harbour comes alive with swimmers, kayaks and boats. Check the city's official events listings for your dates, as major conferences and events can also fill hotels and raise prices.
