What to expect

Daytime

Warm days in Peru in December. A hat starts to earn its keep at midday. Evenings are the comfortable part of the clock.

You can walk at more hours than in the fierce months. Still build in a pause when the sun is high. Nights are easy.

Rain

Rain is not the story in Peru in December. Pack for sun. A shower would be news, not a plan.

Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.
