The Climate in The Rainbow Mountain

Rainbow Mountain is one of the most breathtaking natural wonders in Cusco. Located at 5,200 meters (17,060 ft) above sea level in the heart of the Vilcanota mountain range, it offers a unique experience to visitors with its reddish, greenish, yellow, and violet hues. But beyond the beauty of Vinicunca, it’s essential to be properly prepared to enjoy the experience without setbacks. Below, we explain everything you need to know about the climate, altitude, access routes, and what to bring for your visit to Rainbow Mountain.

What’s the Weather Like at Rainbow Mountain?

The weather at Rainbow Mountain is cold and dry for most of the year, with significant differences between daytime and nighttime due to the high altitude. While there are sunny days, wind and low atmospheric pressure can make it feel much colder.

Rainy season (December to March): The weather is unstable, with frequent clouds, heavy rain, and thunderstorms. Daytime temperatures range from 10°C to 15°C (50°F to 59°F), and nighttime temperatures can drop to 5°C (41°F) or lower.
