BACKGROUND: Coronavirus disease 2019 (COVID-19) has affected millions of people around the world. The infection spreads mainly by inhaling infected droplets. Saudi Arabia is a vast country with different climatic conditions.

METHODS: The study assessed the influence of environmental factors on the spread of COVID-19. Six zones (A to F) have been classified according to climatic conditions. The study was conducted by retrospective analysis of COVID-19 records from the Ministry of Health between the months of September 2020 and August 2021. Environmental data such as average temperature (°C), humidity (%), wind speed (m/s ) and sun exposure (kwh/m2) were retrieved from official sites. The data was analyzed to determine the effect of these factors on the spread of COVID-19. SPSS IBM 25 software was used to perform the analysis and p

RESULTS: According to the results, the infection rate was highest between April and July 2021. Six climate zones experienced high temperatures, low humidity, constant wind flow and intense sun exposure throughout this period. The correlation study revealed a significant (p environmental factors and the spread of COVID-19. Data suggests that during summer conditions, when the weather is hot, less humid and a constant wind with lots of sun exposure, the rate of COVID-19 infection has increased in Saudi Arabia. Poor ventilation and closed habitats in an air-conditioned atmosphere during this period may have played a role in human transmission. Further research on air quality, population mobility and disease is essential, so that precise proactive measures can be designed to limit the spread of infection during specific climatic seasons.
