Weather in Cusco in December
December in Cusco sees average daytime temperatures around 66°F (19°C), with nights cooling down to a brisk 44°F (7°C). This month marks the heart of the rainy season, so expect frequent, often heavy, showers, particularly in the afternoons. Humidity levels are notably higher, often hovering around 70-80%.

What to wear in Cusco in December
Layering is absolutely key for Cusco in December. Think moisture-wicking base layers, a warm fleece or wool mid-layer, and a waterproof and windproof outer shell. While there aren't strict dress codes, locals tend to dress modestly, especially in religious sites, so avoid overly revealing clothing. Comfortable, sturdy, and waterproof footwear is a non-negotiable for navigating slippery streets and muddy trails.

Pro tips
Acclimatize Slowly
Cusco is at a high altitude. Take it easy on your first day or two, stay hydrated, and avoid heavy meals and alcohol to prevent altitude sickness.
Book in Advance for the Holidays
December, especially leading up to Christmas and New Year's, is a popular time. Book accommodations, tours, and train tickets well in advance to secure your spot.
Protect Your Camera Gear
If you're bringing a nice camera, invest in a waterproof cover or dry bag. The rain can be intense, and you'll want to capture those misty, atmospheric shots without worry.
Carry Small Bills
Many smaller shops and vendors prefer cash, and having small denominations (soles) will make transactions much easier, especially in local markets.
Frequently asked
Is December a good time to visit Machu Picchu?
Yes, it can be! While it's the start of the rainy season, the landscape is incredibly lush and green, and you'll often experience misty, atmospheric conditions that make for stunning photos. Rain typically comes and goes, so you'll usually have clear spells. Be prepared for potentially muddy paths.
What are the chances of altitude sickness in December?
Altitude sickness is not tied to the month. Cusco sits at 11,152 feet (3,399 meters), so there's always a possibility. Hydrate well, avoid alcohol and strenuous activity on arrival, and consider speaking to your doctor about medication if you're concerned.
Are tourist sites crowded in December?
Early December can be moderate, but as Christmas and New Year's approach, visitor numbers certainly increase. If you're traveling during the holiday week, expect larger crowds at popular sites like Machu Picchu and the Sacred Valley. Booking tickets and tours well in advance is highly recommended.
What should I do if it rains heavily while I'm out exploring?
Many tour operators and local businesses are well-prepared for rain. Carry your rain gear, and don't be afraid to take refuge in a local cafe or shop. Embrace the experience – often, the rain clears to reveal stunning, refreshed vistas.
What kind of footwear is best for hiking in December?
Waterproof hiking boots with good ankle support are your best friend. Trails, especially the Inca Trail and paths around Machu Picchu, can become very muddy and slippery. Non-slip soles are essential for safety and comfort.
