Lima Monthly Climate

Temperature Overview

Lima experiences relatively mild temperatures throughout the year, with a moderate seasonal variation. Summer highs peak at 26.7°C (80°F) in February, while winter lows drop to around 13.9°C (57°F) in July-September. The city's location along the Pacific coast and the cold Humboldt Current significantly influence its climate.

The warmest period is during summer (December to March) when daytime temperatures consistently range between 24-27°C (75-81°F) and nighttime temperatures remain comfortable at 18-19°C (64-66°F). The coolest period is during winter (June to August), with highs around 19°C (66°F) and lows near 14°C (57°F).

Unlike many cities, Lima's temperature variation between day and night is relatively modest, typically ranging from 5-7°C (9-13°F). This small daily temperature swing, combined with high humidity levels, creates a microclimate that can feel warmer or cooler than the actual temperature suggests.

Best Time to Visit

The best time to visit Lima is during the summer months (December to April), when there is less cloud cover and warmer temperatures. However, each season offers unique experiences:

Summer (December-February) brings the warmest temperatures and clearest skies. This is peak tourist season, perfect for enjoying the city's beaches and outdoor attractions. Humidity remains high but is more comfortable than winter.

Autumn (March-May) offers warm temperatures with gradually increasing cloud cover. This shoulder season provides good conditions for sightseeing with fewer tourists than summer.

Winter (June-August) is characterized by persistent cloud cover and cooler temperatures. While rainfall is minimal, the constant gray skies ("la garúa") and high humidity can make it feel cooler than the actual temperature.

Spring (September-November) sees gradually improving conditions with temperatures slowly rising and cloud cover decreasing. This is another good shoulder season for visiting, with fewer tourists than summer.
