Thinking about a summer trip to Copenhagen? You’ll find the weather mild and comfortable, just right for wandering around the city. Average daytime temperatures usually sit between 16°C (60°F) in June and about 21°C (70°F) in July and August. It’s warm, but you won’t get scorched. Nights cool down, so tossing a light jacket in your bag is a good idea.
The city’s climate feels moderate most of the time, thanks to its spot on the coast and the North Atlantic’s influence. Rain pops up here and there, but showers don’t usually stick around for long. You still get plenty of chances to bike, stroll, or hang out in the parks.
One thing you’ll notice is how long the days are. From early June until mid-July, the sun rises before 5 a.m. and doesn’t set until close to 10 p.m. That means lots of time to soak up the city’s energy, whether you’re at a café or walking along the waterfront. The extra daylight, mixed with comfy temps, really makes summer the best time to see Copenhagen.

Compared to winter, summer rain is lighter and less frequent, but it still shapes daily life. You might need to tweak your plans if a shower rolls in, but rain rarely sticks around long enough to ruin a day.
Cloud Cover and Sunshine
Copenhagen’s summer is a mix of bright days and cloudy stretches. You’ll get long daylight hours, some clouds, and a good balance between sunshine and overcast skies. These patterns really shape how much sun you’ll enjoy as you explore.
Typical Cloudiness
Copenhagen’s summer skies aren’t perfectly clear, but they’re less cloudy than in other seasons. About 45% of summer days are overcast or mostly cloudy, so you still get plenty of light, even when it looks gray outside.
Clouds shift a lot during summer. You’ll often see cumulus clouds in the afternoon, sometimes bringing quick showers. Compared to winter’s thick, low clouds, summer skies feel lighter and more open.
Each month, you get about 10–12 overcast days in June, July, and August. That’s way less than the 16–18 overcast days you’d get in winter. The reduced cloud cover makes summer brighter for outdoor plans.
Sunshine Duration
Daylight is one of the most striking things about Copenhagen in summer. In June, the sun’s up before 5:00 a.m. and doesn’t set until after 10:00 p.m., so you get 17+ hours of daylight. By August, days shorten a bit but still give you about 15 hours of usable light.
On average, you’ll see 8–9 hours of sunshine each summer day. That’s almost twice as much as winter. The extra daylight means you can eat outside, take evening walks, or bike around well into the night.
Long days also make it easier to plan trips out of the city. You can visit beaches or the countryside without worrying about it getting dark early. Mild temps and lots of sun make for comfortable sightseeing.
Clear and Overcast Days
Expect a mix of clear and cloudy days in Copenhagen during summer. About a third of days are mostly sunny, another third partly cloudy, and the rest are overcast. You’ll want to be ready for the weather to change.
Clear days usually come with high-pressure systems, which bring steady weather and blue skies. Those are the best days for swimming in the harbor or relaxing in parks.
Overcast days feel cooler and might bring light showers. The rain isn’t constant, but clouds can hang around for hours. A light rain jacket or umbrella is worth packing, just in case.
This variety keeps the weather interesting, but it’s rarely extreme. You’ll get enough clear skies for outdoor fun, but also a taste of that classic northern European gray.
Daylight Hours and Sunrises
Daylight in Copenhagen changes fast through the summer. June brings long, bright days, but by the end of August, evenings feel noticeably shorter.
Length of Daylight
In June, you’ll see the longest days of the year. Around the solstice, daylight lasts about 17½ hours. By July, days shrink to about 16 hours. In August, you get around 14½ hours of light.
This steady change affects how much time you have outside. June’s long days mean late sunsets and more time to explore. By late summer, evenings come a bit earlier. If you want to make the most of your visit, keep these daylight shifts in mind.
| Month | Average Daylight |
|---|---|
| June | ~17.5 hours |
| July | ~16 hours |
| August | ~14.5 hours |
Earliest and Latest Sunrises
Sunrises in Copenhagen really jump around during the summer months. In mid-June, the sun shows up as early as 4:30 AM, which almost feels absurdly early if you’re not a morning person.
On those longest days, you’ll notice the sky starts to brighten well before the official sunrise, thanks to the long twilight.
By July, the sunrise creeps later, landing somewhere between 4:45 and 5:00 AM. August mornings take on a darker feel, with the sun not making an appearance until closer to 5:30 or even 6:00 AM.
If you’re into early walks or catching that perfect photo, June is your best bet. By late summer, mornings start to feel a bit more normal, so you don’t have to drag yourself out of bed before dawn.
Earliest and Latest Sunsets
Copenhagen’s sunsets can be just as memorable as its bright mornings. The latest sunsets happen in late June, when you might still see the sun hanging on until nearly 10:00 PM.
That means you get these long, drawn-out evenings where the light just sort of lingers, which feels pretty special.
In July, the sunset moves up to about 9:30 PM. By August, daylight slips away faster, and sunsets show up around 8:30 PM.
If you stay in the city for a few weeks, you’ll definitely notice the gradual change. Late June evenings stretch on, perfect for outdoor dinners, festivals, or just wandering by the water. Later in the summer, night falls sooner, and honestly, the city feels a bit calmer and maybe even cozier.
Other Summer Weather Factors
Spend any time in Copenhagen during summer, and you’ll notice steady breezes, moderate humidity, and pretty stable pressure. These things shape how warm or cool it feels outside, maybe even more than the actual temperature sometimes.
Wind Speed and Direction
Copenhagen sits right on the Øresund Strait, so you’ll usually feel light to moderate winds. In summer, the average wind speed hits about 6 mph, which honestly feels gentle compared to the blustery winter.
Most of the time, the wind blows in from the west or southwest, bringing mild maritime air. That breeze helps keep things from getting uncomfortably hot, even in July and August.
If you’re down by the harbor or out on the waterfront, the wind feels a bit stronger than it does tucked away in the city streets. Cyclists especially notice the difference—sometimes the breeze gives you a little boost, other times it’s more of a challenge.
Humidity Levels
Copenhagen’s summer humidity usually sits between 65% and 75%. The air doesn’t often get sticky, even when it’s warm, topping out around 70°F (21°C).
Cooler nights mixed with warmer days keep things comfortable for outdoor activities. Unlike a lot of inland cities in Europe, you probably won’t deal with long spells of muggy, oppressive air.
Clouds do hang around quite a bit. On average, the sky is overcast or mostly cloudy about 45% of the time. That can make the air feel a little heavier, especially right before it rains. If you’re visiting, it’s smarter to pack a few light layers than to load up on hot-weather clothes.
Atmospheric Pressure
In Copenhagen, summer pressure usually sits around 759 inHg. The conditions stay pretty steady, so you won’t see wild swings in the weather.
That steadiness means sudden shifts don’t happen all that often, but you’ll still get passing showers now and then.
You’ll probably notice pressure changes aren’t nearly as wild as what winter brings, when storms barrel across northern Europe.
During summer, the pressure just wobbles a bit, so you might get some drizzle here and there, but it’s rarely a long, soaking rain.
Most visitors feel confident planning outdoor activities because the weather tends to cooperate. Sure, sometimes the pressure dips and the sky gets a bit unsettled, but it’s usually just a blip and doesn’t ruin the whole day.
Honestly, summer feels like one of the easier times to explore the city if you’re hoping for predictable weather.
