In summer there is an average temperature of 25°C.
Lima is built on a desert, has a population of more than nine million, and receives hardly any rainfall. According to some studies it is the second driest capital in the world after Cairo (e.g. The National Environmental Council, CONAM). The city gets almost all of its water from the Rio Rimac and two other rivers with sources high in the Andes. Experts warn that increased demand together with climate change and melting tropical glaciers will cause severe water scarcity in Lima already by 2025. So best to be considerate with water when you visit Lima.
