The climate of Lima
Situated on the arid desert coast of Peru, Lima conforms to a BWh or a subtropical desert climate classification under the Köppen climate classification system. A unique blend of climatic influences impacts Lima's weather, ranging from oceanic currents to coastal geography resulting in a relatively moderate annual temperature range, interspersed with light rainfall predominantly in the cooler months.

The city encounters its warmest periods from December to March where temperatures can reach up to 25.4°C (77.7°F).
Lima’s humidity levels fluctuate from 75% to 79% year-round, contributing to the city's characteristic coastal fog, locally known as garúa.
