The rains can be fierce when they hit, causing landslides and disrupted transportation schedules. Major rains in 2010 led to landslides and the closure of Machu Picchu as well as difficulty accessing parts of the Sacred Valley due to bridges being washed away and roads damaged. Average temperatures during the dry season range from 5 degrees to 19 degrees.

Dry Season:

The dry season runs from April until September. June and July are the driest months but also the coldest with temperatures sometimes dropping below zero.  Average temperatures during the dry season vary from o degrees to 25 degrees during the day.  Temperatures tend to rise around noon due to the strong daytime insulation and the transparency and dryness of the atmosphere. Similarly, the loss of solar radiation can cause temperatures to drop below zero in the evening, night and early morning.
