The impact on sunshine is even more important. Only 34 percent of daylight hours in Lima have sunshine every year.  On average, July and August receive less than one hour a day of sunshine. Lima receives only 1,230 hours of sunshine per year.

The climate of Lima is typical of the coasts of Peru and northern Chile.
