Honestly, if you're looking at the Copenhagen weather forecast 10 days out and seeing nothing but grey icons, don't cancel your flight just yet. Copenhagen in mid-January is basically the final boss of "moody" weather. It's damp. It's dark. The wind coming off the Øresund feels like it’s trying to personally audit your choice of outerwear.
But here’s the thing: the forecast right now—running from Thursday, January 15, through the next week—is actually doing something kinda interesting. We’re moving from a soggy, "is it rain or is it snow?" mess into some genuine, bone-chilling clarity.
The 10-Day Reality Check: What’s Actually Coming
Right now, as of Thursday night, the city is sitting at a crisp 37°F. But "feels like" is the only metric that matters in Denmark, and that’s currently hovering at a much ruder 28°F thanks to a 14 mph wind from the southeast.
If you're out near Nyhavn tonight, it’s cloudy and 99% humidity. Basically, you’re walking through a cold, wet sponge.

The Immediate Mess (January 16 – 17)
Friday is going to be the warmest day of the week, hitting a high of 42°F. Don't get excited. It’s going to be "mostly cloudy" with a 20% chance of rain during the day and snow at night.
Saturday, January 17, is when things get weird. The forecast calls for a mix of rain and snow with a high of 36°F and a low of 35°F. That tiny temperature window means the slush on the ground is going to be incredible. If you don't have waterproof boots, you've already lost.
The Great Freeze (January 19 – 21)
This is the part of the Copenhagen weather forecast 10 days outlook that most people overlook. Starting Monday, January 19, the clouds actually clear out. We’re looking at full sun.
Normally, "sunny" sounds great, but in a Danish January, it means the mercury is dropping.
- Monday: Sunny, High 36°F, Low 33°F.
- Tuesday: Sunny, High 36°F, Low 31°F.
- Wednesday: Partly sunny, High 36°F, Low 31°F.
The humidity drops from the high 90s down to about 76%. It’s going to be that sharp, biting cold that makes your nose turn bright red in five minutes. It’s also the best time to see the city. The light in Copenhagen during these "clear" winter days is low, golden, and perfect for photos, even if you can't feel your fingers.

Why the Wind in Copenhagen is a Different Beast
You’ll notice the wind direction in the forecast is consistently from the southeast or east at around 10 to 18 mph.
In some cities, 15 mph is a breeze. In Copenhagen, because the city is so flat and surrounded by water, that wind acts like a heat-seeking missile for the gaps in your scarf. By the time we hit the end of the 10-day window—specifically Saturday, January 24, and Sunday, January 25—the wind picks back up to 18 mph and the snow showers return.
Temperatures by next Sunday will struggle to break 30°F.
Quick Survival Guide for the Next 10 Days
You've gotta be smart about the gear. Forget the heavy "fashion" wool coat if it’s not windproof.
- The Base Layer: You want wool. Not cotton. Cotton holds moisture, and with 90% humidity, you'll be shivering in twenty minutes.
- The Shell: A windbreaker or a waterproof parka is mandatory for Friday and Saturday's rain-snow mix.
- The Feet: The forecast shows snow showers for the final four days of the cycle. The pavement will be icy and salted.
The "Hygge" Pivot: Making the Weather Work
Look, nobody goes to Denmark in January for the tropical vibes. You go for the atmosphere. When the sun sets at 4:15 PM (and it will), the city transforms.
The "mostly cloudy" conditions predicted for much of next week are basically an invitation to lean into the café culture. While the outside is a bleak 32°F with snow showers, the inside of a place like Atelier Septembre or La Banchina is going to be glowing with candlelight.
Honestly, the best way to handle a Copenhagen weather forecast 10 days out is to plan your outdoor walks for the "sunny" window between Monday and Wednesday, and save the museums or long lunches for the slushy bookends of the week.

What to do when it hits 30°F
- Winter Bathing: If you’re feeling brave (or insane), head to Islands Brygge. The locals take a dip in the 37°F water and then hit the sauna.
- The Glyptotek: It’s a massive winter garden inside a museum. It’s the only place you’ll find palm trees in Copenhagen when it’s snowing outside.
What’s the Move?
If you are traveling during this 10-day window, your most important dates are January 19-21. That is your "adventure" window where the sky clears up. Before that, expect to be wet. After that, expect to be cold.
Next steps for your trip:
Check your footwear today—if they aren't waterproof, buy some beeswax or spray before Saturday's slush hits. Also, download the "Rejseplanen" app; when the snow showers start on the 23rd, you're going to want to know exactly when the next bus is coming so you aren't standing in the wind.
