Traveling to Cusco is one of those life-changing trips almost every traveler has on their bucket list. Not only because of its history, culture, and connection to the Inca world, but also because weather and altitude shape your experience every single day.

One of the most common questions backpackers and young travelers ask is:

• What’s the best time to visit Cusco?

• Is Cusco cold all year?

• Does it rain a lot?

• What clothes should I pack?

The short answer: it depends on the month, the season, and where you go.
The long (and actually useful) answer is this guide.

Cusco has two very distinct seasons, strong temperature changes between day and night, major climate differences between the city, the Sacred Valley, and Machu Picchu, and one key factor that affects everything: altitude.

In this guide, you’ll find a month-by-month breakdown of Cusco’s weather, real temperatures, how it actually feels, what to pack, landscape changes throughout the year, and honest advice based on real traveler experience — not theory.

🏔️ Cusco, Altitude, and Why the Weather Feels Extreme

Before talking about months and seasons, there’s one thing you must understand:

Cusco sits at 3,399 meters (11,152 ft) above sea level.

At this altitude:

• The sun feels much stronger

• Temperatures drop quickly after sunset

• Weather can change fast

• Your body feels cold, fatigue, and dehydration more intensely

Weather also varies depending on where you are:

• Cusco city: cool to cold climate, chilly nights all year

• Sacred Valley: lower altitude, slightly warmer

• Machu Picchu: humid, green, and more stable temperatures

That’s why saying “Cusco is cold” is an oversimplification. The reality is more nuanced.

🌦️ The Two Main Seasons in Cusco

Cusco has two very clearly defined seasons, exactly as many experienced travelers describe.

🌧️ Rainy Season (November to March)

• Frequent rain, usually in the afternoons

• January and February are the wettest months

• Temperatures are more mild

• Nights are less cold than in dry season

• Landscapes are lush and green

Even though it rains, it doesn’t feel extremely cold. The climate is more temperate, but rain can affect trekking and outdoor plans.

☀️ Dry Season (April to October)

• Very little rain

• Strong sun during the day

• Cold in the shade

• Very cold nights

• Bigger temperature contrast between day and night

This is when Cusco’s climate feels more “extreme”: warm sun during the day, freezing temperatures at night.

🌿 Landscapes: Green vs Dry (And Why It Matters)

• Toward the end of dry season, landscapes around the city become much drier

👉 Important exception:
Machu Picchu stays green almost all year, thanks to its humid climate.

Altitude makes everything feel stronger:

Key tips:

• Rest your first day

• Drink plenty of water

• Avoid alcohol initially

• Eat light meals
