The climate of the city is predominantly dry in winter, autumn and spring due to low atmospheric humidity and a level of precipitation corresponding to that of a desert climate (BWk, according to the Köppen climate classification). On average, Arequipa has 300 days of sunshine each year. Typically, temperatures neither exceed 25 °C (77 °F) nor drop below 5 °C (41 °F). The wet season lasts from December to March and is marked by the presence of clouds in the afternoon and low rainfall. In winter (June and July), the temperature drops to an average of 6 °C (43 °F). The average relative humidity is 46%, with an average high of 70% in the summer season and a minimum average of 27% during autumn, winter and spring, according to data from the Goyeneche Hospital weather station.
The mountainous topography surrounding the Chili River valley affects low-pressure fronts and local winds. These winds occur mainly in the early morning and the evening. Mountain breezes typically flow northeast, and valley breezes typically flow southwest. Wind velocity fluctuates between 1.5 m/s and 2.5 m/s.
Solar radiation in Arequipa ranges from 850 to 950 W/m 2 (watts per square meter), one of the highest levels of radiation in South America and the highest recorded in Peru. Arequipa's proximity to the Atacama Desert and pollution contribute to the higher levels of radiation.
