Copenhagen experiences a temperate oceanic climate with mild summers, cool winters, and year-round moisture from the surrounding seas.
Rain falls throughout the year with no true dry season, making a waterproof jacket or compact umbrella essential kit rather than seasonal accessories.
Temperatures range from around freezing in January to a modest 22°C in July, rarely reaching extremes but capable of surprising visitors with chilly summer evenings.
The near-constant wind from the Baltic Sea and North Sea amplifies the cold in winter and makes layering more effective than single heavy coats.
The city's cycling culture and flat terrain mean your clothing needs to function on a bike in sideways drizzle, not just on foot.
