Copenhagen Weather Through the Year
The temperature
A January average of 1.4 °C is not severe by northern European standards, and a July average of 18 °C is not hot. The range is narrow, which is the useful thing: Copenhagen rarely surprises you in either direction. The exception is a winter cold wave, when the temperature can drop to minus 15 or minus 16 °C, and at that point a 90-minute walk standing still on a square becomes a different proposition.
Rain and sun
About 660 mm of rain falls across the year, spread rather than concentrated, with August the wettest month at around 80 mm. Sunshine runs to roughly 1,780 hours a year, which works out at about an hour and a half a day in January against eight and a half in July. Those two numbers together explain why summer here feels endless and winter feels like an indoor season.
What it means for a walk
The guided ghost walk runs rain or cold, which is the operator's position and not a hope. That puts the responsibility on your clothing: a waterproof layer rather than an umbrella, because you will be standing still while somebody talks, and standing still is colder than walking. What to wear goes into it properly.
The thing that actually decides your evening is not the temperature, it is the light. On 21 June the sun sets at 9:57 pm; on 31 October it sets at 4:35 pm, and the day length drops 2 hours 13 minutes across October alone. See when it gets dark and the best month to visit.
