How do temperatures differ between Algeria’s coast, High Plateau, and Sahara regions?

Algeria’s climate varies significantly across its three primary geographic regions, with temperature ranges becoming increasingly extreme as one moves from the coast toward the interior.1

Coastal Zone

The coastal region experiences a Mediterranean climate, characterized by mild, rainy winters and warm, dry summers. In Algiers, for example, summer afternoon temperatures typically reach 83 °F (28 °C), cooling to about 70 °F (21 °C) at night. Winter temperatures are moderate, generally ranging between 49 and 59 °F (9 and 15 °C).1

High Plateau

The High Plateau is defined by greater temperature variability and more extreme seasonal shifts than the coast. Summers are hot, with afternoon temperatures often exceeding 100 °F (38 °C) before dropping to roughly 50 °F (10 °C) at night. Winters are notably cold, with daily temperatures ranging from approximately 28 °F (−2 °C) at night to 60 °F (16 °C) during the day.1

Sahara

The Sahara region exhibits the most extreme diurnal and annual temperature ranges in the country. Daily temperature swings are significant, and the climate is marked by intense heat during the summer months.12
