Cusco, the jewel of the Peruvian Andes, is a destination that enchants travelers year-round — but it becomes truly magical during the end-of-year season. Knowing what the weather is like in Cusco in December and January will help you plan a comfortable, safe, and unforgettable trip.
Staying at a hotel in the Sacred Valley is a smart choice if you’re looking for a slightly warmer climate and lower altitude before exploring Cusco’s iconic landmarks and the wonders of the Andes.
Cusco’s Climate: General Characteristics and Seasons
The climate of Cusco is classified as high-altitude temperate, with average annual temperatures ranging between 5°C and 20°C (41°F–68°F) depending on the time of day and elevation. Located at 3,399 meters (11,150 ft) above sea level, the temperature can shift dramatically — bright sun at noon and chilly nights are typical.
Cusco experiences two main seasons:
- Dry season (April to October): sunny days, blue skies, and very little rainfall — perfect for visiting Machu Picchu and hiking the Andes.
- Rainy season (November to March): afternoons often bring short, intense showers or thunderstorms, especially in January and February. The trade-off? Verdant valleys, blooming landscapes, and fewer crowds.
According to the National Meteorology and Hydrology Service of Peru (SENAMHI, 2025), Cusco receives an average of 130 mm of rain in December, with humidity levels around 75%, making it a vibrant time to experience the region’s natural beauty.
What the Weather Is Like in Cusco in December and January
During December and January, Cusco is in its rainy season, but that doesn’t mean it’s a bad time to visit. Mornings are usually sunny with clear skies, while rain tends to arrive in the late afternoon or evening — often in short bursts rather than all-day storms.
- Average temperature: 8°C (46°F) low / 20°C (68°F) high.
- Rain: frequent, mostly in the afternoons.
- Sunlight: mornings are bright and warm, with intermittent clouds later in the day.
One major advantage of traveling at this time is that tourist crowds are smaller. According to the Cusco Tourism Observatory (2024–2025), visitor numbers drop by around 25% compared to the high season (June–July), meaning shorter lines and more peaceful experiences.
So, if you understand what the weather is like in Cusco and plan accordingly, December and January can actually be the perfect time for a calm and affordable adventure.
What to Pack for a Trip to Cusco During the Holidays
Packing smartly is essential to enjoy your trip to Cusco during this time of year. The key is layering — you’ll need to be ready for sunshine, rain, and cool mountain evenings.
Recommended clothing:
- Base layer: breathable long-sleeve shirts.
- Middle layer: a fleece or wool sweater for warmth.
- Outer layer: a waterproof jacket or poncho.
- Pants: quick-dry, lightweight trekking pants.
- Footwear: non-slip trekking shoes or waterproof sneakers.
- Accessories: hat, sunglasses, sunscreen, and insect repellent.
A waterproof backpack cover is also handy to protect your gear from sudden rain.
If you’re staying in lower-altitude areas like the Sacred Valley, expect slightly warmer and more humid conditions — perfect for lighter daytime clothing.
Tips to Adapt to Cusco’s Climate and Altitude
Beyond the weather, altitude is an important factor to consider. Cusco sits at nearly 3,400 meters (11,150 ft) above sea level, and many travelers experience mild altitude sickness or “soroche” upon arrival.
Tips for smooth acclimatization:
- Rest on your first day: avoid strenuous activity right after arrival.
- Stay hydrated: drink plenty of water and try coca tea, a traditional local remedy.
- Avoid alcohol and heavy meals: especially during your first 24 hours.
- Start your stay in the Sacred Valley: its lower altitude (around 2,800 m / 9,200 ft) helps you adjust gradually.
According to the Peruvian Ministry of Health (MINSA, 2025), about 60% of tourists report mild symptoms of altitude sickness, which typically disappear within a couple of days. Taking it easy at first will ensure you enjoy your sightseeing to the fullest.
Recommended Activities According to Cusco’s Weather
The weather in Cusco during the end of the year opens up unique opportunities for travelers who enjoy nature, culture, and adventure. Even with rain, most activities can be done safely — just plan around the weather.
Top things to do:
- Cultural experiences: visit museums, colonial churches, and artisan markets in Cusco’s historic center.
- Short outdoor trips: explore nearby ruins like Sacsayhuamán, Q’enqo, or Tambomachay in the morning.
- Sacred Valley excursions: Pisac, Ollantaytambo, and Maras often have milder weather than the city itself.
- Thermal baths: relax in natural hot springs in Aguas Calientes or Lares on cooler days.
- Festivities: Christmas in Cusco is magical with the Santurantikuy artisan fair, and New Year’s Eve celebrations fill the Plaza de Armas with more than 20,000 people enjoying traditional music and fireworks.
When afternoon showers hit, it’s the perfect excuse to savor local cuisine — like quinoa soup, trout, or alpaca steak — in a cozy restaurant overlooking the Andes.
Conclusion: Enjoy Your Trip to Cusco with the Best Preparation
Traveling in December or January can be an unforgettable experience if you understand what the weather is like in Cusco and come prepared. The green landscapes, festive atmosphere, and smaller crowds make this one of the most rewarding times to visit.
Plan ahead, pack layers, take time to acclimatize, and embrace the changing weather as part of Cusco’s charm.
