The temporal variation of PM2.5 concentrations is evaluated in two cities by this study: Metropolitan Lima and Arequipa in the years 2019 – 2021 and the influence of the social distancing policies established by the Government due to SARS CoV-2 pandemic in the PM2.5 concentrations in both years 2020 and 2021. PM2.5 concentrations data from the National Service of Meteorology and Hidrology (SENAMHI by its acronym in Spanish) for Metropolitan Lima city and PM2.5 concentrations data from the Regional Directorate of Environmental Health (DIRESA by its acronym in Spanish) of Arequipa for Arequipa city were used. At the same time, meteorological data from SENAMHI were used for both cities. Temporal variation graphs for different temporal scales and boxplots for daily, diurnal and nocturnal scales were made. In addition, daily variation graphs were made for the period March 15 – April 30, including boxplots and descriptive statistics calculations. The results showed that in all time scales, PM2.5 concentrations are higher in Metropolitan Lima than in Arequipa in the three years of study, where in the first city there are more concentrations that exceed the Environmental Quality Standards (ECA by its acronym in Spanish) of Perú than in the second city. All PM2.5 concentrations exceed the WHO guideline. At any time scale, nighttime concentrations were generally higher than daytime concentrations in 2019 in both cities, while daytime concentrations were higher than nighttime concentrations in 2021. In the period March 15 – April 30, PM2.5 concentrations were lower in 2020 than in 2019 and 2021 in both cities.
