Summer
Dec → Feb- 2 rainy days · 10 mm
- 10.9 h of sun
In short: May to September, during the dry season in the Andes: clear skies over Cusco, the Sacred Valley and Machu Picchu, with cold nights at altitude. The coast follows the opposite rhythm: Lima and Paracas enjoy their sunny summer from December to March (25 °C in February in Lima), when the rains fall on the Andes.
Best avoided: January to March in the Andes: heavy rain, slippery trails and a risk of mudslides, with the Inca Trail closed in February.

What comes back every year, and when. These events fill the hotels and push prices up: something to aim for or to avoid, depending on what you want.
Puno dances for two weeks on the shores of Lake Titicaca, with thousands of costumes and brass bands.
Flower carpets, night-time processions and bulls let loose in the streets during the ten days before Easter.
