Although Qatar is close to the sea, it enjoys a tropical desert climate. Summers are hot and long, with the highest temperature reaching 46°C, winters are cool and dry, with the lowest temperature being 7°C and the lowest temperature being 7°C. the average annual precipitation is only 125 mm.
It's not just size that determines climate, it's also size that determines the amount of heat in an area. What determines the amount of precipitation in a region is ocean water vapor. Ocean water vapor is affected by the monsoon cycle and is similar in dimension to that of Qatar, but due to the influence of the southeast monsoon and southwest monsoon, it is rainy and humid. .
To put it simply, the local ocean water in Qatar has evaporated, but has been blown to other places by the wind, so it is very hot but very dry.
