Planning a trip to Cusco, Peru? One of the most important decisions you'll make is when to visit this magnificent ancient capital of the Inca Empire. Located at 11,150 feet (3,400 meters) above sea level in the Andes Mountains, Cusco's unique high-altitude climate creates distinct seasonal patterns that dramatically affect your travel experience.

Whether you're dreaming of trekking the legendary Inca Trail to Machu Picchu, exploring the spiritual landscapes of the Sacred Valley, or simply immersing yourself in centuries of history and culture, understanding Cusco's climate and seasonal rhythms is essential for planning an unforgettable journey.

Understanding Cusco's High-Altitude Climate

Cusco experiences dramatic temperature variations between day and night, regardless of season. Daytime temperatures are generally mild and pleasant, while nights can be surprisingly cold. The city receives most of its rainfall during the austral summer (November-March), with a distinct dry season from May through September.

The altitude—nearly two miles above sea level—significantly impacts how you'll experience the climate. Read our complete altitude sickness guide for detailed preparation tips.

The Dry Season (May–September): Peak Travel Time
