Amsterdam has a temperate maritime climate with mild summers, cool winters, and weather that changes faster than a cyclist at a red light.
Rain falls year-round with no true dry season, meaning waterproof layers are as essential as your front door key.
Temperatures range from around 0°C in winter to 22°C in summer, with extremes rare but grey skies remarkably reliable.
The persistent wind off the North Sea cuts through inadequate clothing with impressive efficiency, particularly along the canals.
Layering is the local religion here—the ability to add or shed pieces within a single afternoon is what separates tourists from residents.
