The honest headline on Copenhagen weather: it’s mild, it’s changeable, and it’s rarely extreme. The city sits at 55°N — the same latitude as Moscow — but the sea keeps it gentle. Expect cold, dark winters near 0°C, mild springs (4–13°C), warm-not-hot summers (15–22°C) and crisp autumns. Daylight swings hard, from about seven hours in December to 17½ at the June solstice, and rain can show up in any month. Pack layers and a small umbrella whenever you come, and you’re most of the way there.
That’s the short version. Below is the full month-by-month picture — temperatures, daylight, rainfall and what each month actually feels like on the ground — so you can plan properly. For the bigger decision of which season suits your trip, start with our best time to visit Copenhagen guide; this page is the weather detail that sits underneath it.

A quick read of that table tells you most of what matters: July and August are the warmest and wettest, February through April are the driest, and the daylight column is where the drama really lives. Now let’s walk through the year month by month.
Month by month, in detail
January
This is the coldest, darkest month — around 0°C on average, with lows near -2°C and the odd cold snap down to -10°C. You get barely seven to eight hours of daylight, and it’s often grey. Snow shows up occasionally but rarely settles for long. The upside? It’s the cheapest month to visit and the city leans hard into cosy: candlelit cafés, warm museums, and proper hygge in Copenhagen. Come for the indoor life, not the sightseeing. Our winter guide has the full playbook.
February
February feels a lot like January on the thermometer (still around 0°C), but the light is quietly coming back — you’ll have nine to ten hours by the end of the month, and February is also the driest month of the year at just 31 mm of rain. It’s the cheapest stretch for hotels, the Copenhagen Light Festival brightens the dark evenings, and Winter in Tivoli reopens mid-month for families. Good for museums, coffee and design shopping; not for anything that needs to happen outdoors.
March
March is when the thaw begins — averages around 4°C, and daylight jumps to 12–13 hours by the end of the month once the clocks change. The first crocuses appear in the parks, but don’t be fooled: it’s still genuinely cold, wind off the harbour bites, and you’ll want winter layers. Prices stay in shoulder-season territory. It’s a fine month for a cheap city break if you don’t mind grey. For the full spring arc, see Copenhagen in spring.
April
April is when spring properly lands — around 8°C on average, 14–15 hours of daylight, and the cherry blossoms peaking at Bispebjerg Cemetery and Langelinie Park in the last week or so. Tivoli Gardens opens for its summer season. It’s also one of the drier months (37 mm), though a passing shower is always on the cards, so keep packing layers. Great for blossom photography and a first taste of terrace weather without the summer prices.
May
May might be the sweet spot of the whole calendar. Averages around 13°C, daylight stretches to 15–17 hours, the city is in full bloom, and café terraces are open everywhere. Crowds haven’t really arrived yet and prices sit below the summer peak. The Distortion street festival takes over Nørrebro and Vesterbro toward the end of the month. If you want near-summer weather without the July squeeze, this is your month — great for cycling, parks and long, slow afternoons.
June
June brings the longest days of the year — around 17°C on average and a staggering 17 to 17.5 hours of daylight at the solstice, when the sky barely goes fully dark. Sankthansaften (midsummer) bonfires light up the beaches on June 23, and Roskilde Festival kicks off at the end of the month. Harbour swimming season is underway. It’s warm, bright and not yet as packed as July — for most first-timers this is the pick of the summer.
July
July is the warmest month, peaking around 22°C, with 16–17 hours of daylight and the harbour baths at full capacity. It’s also the wettest month on the calendar (67 mm), so those long sunny days come with the occasional sharp shower. The Copenhagen Jazz Festival and Tivoli’s Friday Rocks concerts fill the calendar, and this is peak tourist season — book accommodation two-plus months ahead. It’s the busiest month for a reason; our July guide covers how to enjoy it without the queues.
August
August is July’s slightly cooler twin — a 21°C peak, still warm enough for the last of the harbour swimming, and a touch wetter-feeling as the summer starts to turn. Locals drift back from their holidays mid-month, and the Copenhagen Cooking food festival lands late summer. The second half quietens noticeably as school holidays end, which makes late August a smart window: summer warmth, thinning crowds. Read more in our summer guide.
September
September is the shoulder season locals quietly love — around 17°C, 12–14 hours of daylight, mild and settled, with far fewer crowds and lower prices than the peak. The first two weeks often still feel like summer. If you want the best balance of decent weather and breathing room, this is arguably the single best-value month of the year, edging out even May. See how autumn unfolds in our fall guide.
October
October is peak autumn — around 12°C, 10–12 hours of daylight, and the foliage turning gold in Frederiksberg Have and the Lakes. Cosy café season begins in earnest, and Halloween takes over Tivoli all month. Rain is frequent (60 mm) and the wind can make it feel colder than the thermometer says, so pack proper layers and a waterproof. Lovely for photography and hygge; less so if you need blue skies.
November
November is the toughest month for weather — around 7°C, only 8–10 hours of daylight by month’s end, and a lot of grey. It’s the darkest stretch before Christmas, and honestly, many locals just grit their teeth through it. The saving grace: the Christmas markets and Tivoli’s Christmas season open in the last week or two, which flips the mood entirely. If you can time your visit to that opening weekend, do — otherwise it’s a month for museums and early hygge.
December
December is dark but magical — around 3°C and just seven hours of daylight, the shortest days of the year. But this is when Copenhagen turns on the charm: Tivoli’s Christmas season, markets at Kongens Nytorv, Tivoli and Hans Christian Andersen Square, gløgg on every corner and lights everywhere. The short days become part of the appeal. New Year’s Eve is genuinely wild. Everything you need is in the December guide and our roundup of the Copenhagen Christmas markets.
Rainfall patterns
Copenhagen averages 170 rainy days a year, so rain is possible in any month — but it’s usually light and passing rather than an all-day soaking. Here’s the pattern worth knowing:
- Wettest months: July, August and October (60–67 mm).
- Driest months: February, March and April (31–39 mm).
- Quick changes: the weather can flip within hours — sun then shower then sun is typical.
- Maritime moderation: the Baltic keeps extremes rare; it’s seldom above 28°C or below -10°C.
- Snow: about 5–10 days a year, usually December to February, and it rarely sticks for long.
- The golden rule: pack an umbrella and waterproof shoes, every single trip.
Daylight by month
At 55°N, daylight is the real story of the Copenhagen year — it changes the whole feel of a trip far more than a few degrees on the thermometer:
- December solstice (Dec 21): about 7 hours; roughly 8:38–15:38.
- March equinox (Mar 20): about 12 hours; roughly 6:25–18:30.
- June solstice (Jun 21): about 17.5 hours; roughly 4:25–21:55.
- September equinox (Sep 22): about 12 hours; roughly 6:55–19:00.
- Daylight saving: the clocks change on the last Sunday of March and the last Sunday of October.
- Twilight bonus: long northern twilight adds an hour-plus of usable light beyond sunrise and sunset — late June evenings barely get dark at all.
The best-weather months, ranked
If you’re choosing purely on weather (and a bit on crowds), here’s how the months stack up:
- July — warmest and longest, peak summer everything (but peak crowds and prices too).
- June — long days, midsummer magic, a touch cooler and calmer than July.
- May — full bloom, mild, and blessedly crowd-free.
- August — warm, still swimmable, quieter in its second half.
- September — mild shoulder season with fewer people and lower prices.
- April — cherry blossoms and lengthening days, if you don’t mind the chill.
What to pack for the weather
Some things go in the bag no matter which month you pick:
- A compact umbrella — rain is never far away.
- Waterproof, comfortable shoes — wet cobblestones plus a lot of walking.
- Layers — the temperature can shift a lot between morning and afternoon.
- A light scarf — useful even on summer evenings by the water.
- Sunglasses — for long summer days and bright winter glare off snow.
- A Type C/E plug adapter — standard European sockets.
Then add the season-specific extras:
- December–February: a heavy coat, thermal layers, a warm hat, gloves and boots with grip.
- March–May: a medium jacket, layers and comfortable walking shoes.
- June–August: light layers and t-shirts, a light sweater for evenings, and swimwear.
- September–November: a medium jacket, a scarf and water-resistant footwear.

Summer (Jun–Aug) sits at 15–22°C with 16–17.5 hours. Autumn (Sep–Nov) cools from 14 down to 8°C with 8–14 hours. Rain is possible in any of them.
What is the warmest month in Copenhagen?
July, peaking around 22°C, with overnight lows still near 14°C. August follows at about 21°C and June at a 20°C peak. Genuine heat above 28°C is rare and rarely lasts more than a day or two.
What is the coldest month in Copenhagen?
January and February are tied at roughly 0°C on average. Cold snaps can reach -10°C, but typical lows sit near -2°C, and anything below -15°C is unusual. Snow falls on 5–10 days a year and usually melts quickly.
Does it rain a lot in Copenhagen?
Yes — about 170 rainy days a year, spread fairly evenly, with the wettest stretch July to October and the driest February to April. The good news is it’s usually light and passing rather than relentless. Carry an umbrella and you’ll barely notice most of it.
How long are Copenhagen days in summer?
Daylight peaks at about 17.5 hours around June 21. The sun rises near 4:25 am and sets near 9:55 pm, and northern twilight adds another hour-plus on each side — so late June evenings barely get properly dark. It’s one of the real joys of a midsummer visit.
How dark are Copenhagen winters?
Deep winter bottoms out at about seven hours around December 21, with the sun up roughly 8:38 am to 3:38 pm. Add twilight and you get maybe nine usable hours. Plenty of locals find it hard going — which is exactly why hygge, candles and Christmas lights matter so much here.
When is the best weather to visit Copenhagen?
July and August are warmest but busiest. May and June give the best balance of warmth, long days and manageable crowds. September is the pick for a milder, cheaper shoulder trip. For the full trade-off by traveller type — crowds, prices and events — check the season-by-season overview linked below.
Does Copenhagen get snow?
Yes, on about 5–10 days a year, usually between December and February. It rarely piles up more than a few centimetres and seldom lasts, thanks to the mild maritime climate. Most winter days are cold rain or freezing fog rather than a picture-postcard snowfall.
Final thoughts
The weather here is changeable but almost never extreme, which is oddly freeing — you don’t need to obsess over the forecast, you just need to pack for a bit of everything. July and August bring the warmth and the crowds; May, June and September give you the best balance of good conditions and elbow room; December trades daylight for pure Christmas magic; and January and February are cheap but hard. Bring an umbrella, comfortable waterproof shoes and a couple of layers whatever month you choose, and Copenhagen will treat you well.
March is the month the numbers turn. Sunshine climbs from 2.3 hours a day to about four, daylight runs from just under eleven hours to a little over thirteen, and the clocks go forward at the end of it. The detail is in our guide to Copenhagen in March.
