What is the warmest Mediterranean country? The warmest Mediterranean country is Libya, followed by Egypt. The temperature of 57.8 °C that was measured on September 13, 1922 was the highest ever recorded on the planet. Even in spring and autumn here are possible values of almost 50°C in the shade!
Moreover, this is the only part of the Mediterranean coast to has a tropical climate. This is not surprising because the country is located in the southern-most part of the Mediterranean.
Here is the famous Gulf of Sidra (or Sirte). The average day-time temperature in January along the coast of the gulf and in the cities of Tripoli and Benghazi is usually about 17 – 20°C.
It can get, however, significantly higher, reaching values to about 22 – 23 and sometimes even 25°C.
