Correlation between Weather and COVID-19 Cases: An Extensive Study Covering All Provinces in Saudi Arabia

Meteorological factors have shown correlation with many infectious diseases. This study deals with analyzing the correlation between weather conditions and the daily COVID-19 cases reported in various cities across the Kingdom of Saudi Arabia (KSA) during March to July 2020. The analysis was carried out individually for the most affected cities in different provinces. Spearman correlation was used to find the association between the infections reported and weather parameters such as minimum temperature, maximum temperature, relative humidity and precipitation. It was observed that for almost all cities, COVID-19 cases reported daily were positively correlated with minimum temperature and maximum temperature while they were inversely correlated with relative humidity and precipitation.
