La Paz sits at a staggering 3,640 meters above sea level, which makes it the world's highest administrative capital and gives it a perpetually spring-like climate that defies its tropical latitude.

The wet season brings frequent afternoon downpours between November and March, making waterproof layers and quick-dry fabrics essential despite the relatively warm days.

Temperatures hover between 5°C and 18°C year-round, with the thin air allowing dramatic swings between midday sun and frigid nights regardless of season.

The high altitude means intense UV radiation and dry air that can catch lowlanders off guard, particularly during the cloudless dry season months.

Layering is the local religion here—you'll shed and add clothing multiple times daily as you move between sun-drenched plazas and shaded colonial streets where the temperature drops instantly.
