Lima December weather sets the stage for a season of vibrant celebration in Peru’s capital. As the southern hemisphere leans into summer, the city experiences a unique combination of coastal warmth and urban energy. December marks the height of the tourist season, drawing visitors eager to experience Christmas festivities alongside long, sun-drenched days. Understanding the specific conditions helps travelers pack appropriately and plan activities with confidence.
Summer Heat and Coastal Influence
During December, Lima experiences its summer season, with average high temperatures typically ranging from 24°C to 28°C (75°F to 82°F). The Humboldt Current continues to moderate the climate, preventing the heat from becoming oppressively humid compared to inland regions. While the thermometer might suggest tropical warmth, the ocean breeze often provides a pleasant relief in the afternoon. This balance makes outdoor dining and sightseeing far more comfortable than one might expect for a city so close to the equator.
Sunshine and Daylight
December offers some of the longest daylight hours of the year in Lima, with approximately 13 hours of sunshine. Sunrise occurs around 5:45 AM, providing ample morning light for early excursions, while sunset stretches past 7:45 PM. This extended daylight supports a wide range of activities, from morning beach visits to evening outdoor concerts. The intensity of the sun remains significant, making sun protection a non-negotiable part of any wardrobe.

Average humidity: 65-80%
Average rainfall: 1-3 mm (minimal)
Sea temperature: 22-24°C (72-75°F)
Urban Festivities and Cultural Shifts
The city transforms in December with decorations, nativity scenes, and festive lights illuminating historic districts like Miraflores and Barranco. Locals and visitors alike fill parks and coastal walkways, creating a lively atmosphere that persists late into the evening. Many businesses adjust hours to accommodate holiday travel, while restaurants feature special menus highlighting seasonal ingredients. This period captures the cultural heart of Lima, where tradition meets contemporary celebration.
Packing for December Conditions
Travelers should prioritize lightweight, breathable fabrics such as cotton and linen for daytime comfort. A light jacket or cardigan becomes essential for air-conditioned indoor spaces and cooler coastal evenings. Swimwear is necessary for hotel pools and beach visits, but modest attire remains required when visiting churches or residential neighborhoods. Sunglasses with UV protection and a wide-brimmed hat provide defense against the strong southern sun.
Navigating the City During Peak Season
December is the busiest month for tourism in Lima, leading to higher accommodation prices and increased crowds at popular attractions. Booking flights and hotels well in advance is strongly recommended to secure favorable rates and preferred locations. Traffic congestion intensifies near tourist hotspots and beach areas, particularly on weekends. Utilizing ride-sharing services during the evening hours can simplify transportation through the bustling holiday crowds.
Rainfall remains minimal throughout the month, but brief coastal showers can occur, particularly in early December. These sudden bursts are typically short-lived and clear quickly, leaving behind a fresh atmosphere. The Pacific Ocean maintains a comfortable temperature for swimming, though the water feels cooler than air temperatures suggest. Layering options help adapt to the temperature differences between sun, shade, and sea.
