Lima sits in a coastal desert yet remains perpetually shrouded in garúa, a thick mist that cloaks the city from May to November without producing meaningful rain.
The wet season brings occasional drizzle rather than downpours, making waterproof footwear more useful than umbrellas most of the year.
Temperatures hover between 15°C and 28°C year-round, never scorching but never cold, creating a mild monotony that locals call eternal spring.
High humidity combined with persistent cloud cover creates a damp chill that feels colder than the thermometer suggests, especially in the garúa months.
Layers are the Lima uniform: the grey sky and coastal breeze mean a light jacket at breakfast often stays on until sunset.
Lima follows a wet-dry tropical pattern rather than four seasons, though its coastal desert location makes it cooler and greyer than visitors expect from a tropical city.
