On a very thin strip of the northern coast the rainfall can be as high as 410 mm (16 in), with most of the rainfall between October and March. Snow falls on Sinai's mountains and some of the north coastal cities such as Damietta, Baltim, Sidi Barrany, etc. and rarely in Alexandria, frost is also known in mid-Sinai and mid-Egypt.Temperatures average between 80 °F and 90 °F in summer, and up to 109 °F on the Red Sea coast. Temperatures average between 55 °F . and 70 °F in winter. A steady wind from the northwest helps hold down the temperature near the Mediterranean coast. The Khamaseen is a wind that blows from the south in Egypt in spring, bringing sand and dust, and sometimes raises the temperature in the desert to more than 100 °F.
