Quick verdict
Peak season: May–Sep. Shoulder: Apr, Oct. Low: Jan–Mar, Nov–Dec.
Cusco has two main seasons: a dry season (May-October) and a wet season (November-April).
What's the weather like in Cusco by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Cusco during May–Sep?
Clear, sunny days with almost no rain. Nights are cold, especially in June and July when temperatures can drop below freezing.
Shoulder season (Apr, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Nov–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
