Temperature Controls in the city of Cairo in Egypt

The most populated city is Egypt is Cairo, which is also the countries capital. Cairo has the latitude and longitude positions of 29º52 North and 30º21 East. The warmest months in Cairo are July and August, both with an average monthly temperature of 84.2 degrees Fahrenheit. The coldest month in Cairo is January with an average month temperature of 57.2 degrees Fahrenheit (World Weather Online). The annual range of temperature for Cairo is 70.7 degrees Fahrenheit.

In class, we learned about different temperature controls. Those being: ocean currents, altitude, differential heating, geographic location, cloud coverage and albedo. Egypt is one of the hottest and driest countries in the world due to its geographic location. Cairo is more toward the right side of Egypt, while on the left of the Nile is a vast, and scoring hot desert. Since the winds blow across this hot desert, it blows hot air right in to Cairo and many other cities. Plus when this wind blows over the desert, it carries large quantities of sand and dust, which may also cause temperatures to rise.

I think all of the temperature controls learned in class impact Cairo's hot and dry climate in some way. I think altitude, geographic location and cloud albedo make Cairo hotter, while ocean currents and differential heating make Cairo cooler than shall I say, Al Harrah. Al Harrah is closer to the center of Egypt, with a much hotter temperature than Cairo. This city is not close to any open water, making for no cool wind from these oceans/ seas.

As sea level rises I believe Cairo's temperature will slowly decrease. When sea level rises Cairo will get closer and closer to open water. Thanks to differential heating, water does not change temperatures as fast as land. Winds over the water and the surrounding areas will be cooler.
