The Cusco dry season is in full effect — the sky is clear, rainfall is infrequent, and the Inca Trail is accessible without the mud that defines the rainy season.

What Is the Weather Like in Cusco in June?
June in Cusco delivers the kind of Andean days that make for great photos and rewarding hikes. The weather in Cusco this month means sunny days, sharp mountain air, and strong sun during daylight hours. Morning mist sometimes settles over the city of Cusco before burning off by mid-morning.
June is the beginning of the driest stretch of the year. Evenings cool quickly after sunset — the temperature swings from a comfortable 17°C at midday to near freezing overnight. Walking the cobblestone streets is easy and pleasant in the day, but bring a proper jacket for anything after 6 PM. This is a pleasant climate by day, but don’t underestimate the nights.
Temperature in June in Cusco
Daytime temperatures sit between 18°C and 20°C — warm in the sun, noticeably cooler in the shade given the altitude. The high temperature of 20°C is typical for the month of June, with UV intensity extreme at 3,400 meters.
The low temperature at night often drops to 2–5°C. This is colder than most visitors expect, especially those arriving from Lima or coastal Peru. April and May are slightly warmer at night; July and August are comparable. Pack for a major swing within the same day.
Rainfall in Cusco in June
June is a genuinely dry month. According to climate data from Servicio Nacional de Meteorología e Hidrología del Perú (SENAMHI), June averages fewer than 20mm of precipitation — roughly one or two brief showers across the entire month.
June is the beginning of the dry season, marking the end of the rainy season that peaks during January and February. When rain does occur, it arrives as a short afternoon shower. Rainfall is infrequent and unlikely to disrupt plans. Bring a packable rain layer, but don’t let low forecast percentages deter you.
Humidity in Cusco in June
Humidity in June runs low — typically 40–55%. Combined with altitude, the air feels dry and thin, especially in the first few days of acclimatization.
Low humidity keeps the heat index manageable and means sweat evaporates quickly on hikes. However, dry air at altitude can cause chapped lips, dry sinuses, and mild headaches. Hydration matters more here than at lower elevations — including in Lima, where humidity is considerably higher.
Is June a Good Time to Visit Cusco? (Tourist Season)
June marks the start of high tourist season in Cusco. The weather conditions are optimal, bringing high demand from international visitors and domestic Peruvian travelers. Inti Raymi — the Anniversary of Cusco and Festival of the Sun — falls on June 24th and draws massive crowds to Sacsayhuamán.
Book accommodation, Inca Trail permits, and Machu Picchu entry well in advance. Permits for June and July typically sell out months ahead. If you want to beat the crowds slightly, consider arriving in the first two weeks of June before Inti Raymi week peaks. May to September represents the full peak window; June sits near the top of it.

Seasonal Travel Tips for Visiting Cusco in June
- Acclimatize first. Spend 1–2 days resting before trekking. This matters more than most visitors expect, especially if flying in from Lima at sea level.
- Plan morning starts. Schedule major hikes for 7–10 AM — light is best and afternoon crowds haven’t peaked yet.
- Layers are non-negotiable. The daytime-to-evening temperature swing is large enough to require two entirely different outfits.
- Book Inca Trail permits 4–6 months out. June dates fill fast; last-minute permits don’t exist.
- Arrive at Machu Picchu at opening. Crowds build by mid-morning; the 6 AM entry window offers quieter conditions.
- Altitude medication. Soroche affects a meaningful percentage of visitors regardless of fitness level. The CDC’s travel health guidance for Peru covers acetazolamide (Diamox) and other options.
- Carry cash. Smaller restaurants and transport around Cusco often don’t accept cards.
Weather Hazards in Cusco in June
