With such a large territory, the weather and climate in Algeria have vast variations. The northern coastal regions, which include the capital city Algiers, enjoy a Mediterranean climate, with mild and wet winters balanced out by hot summers. Temperatures average around 54°F (12°C) in winter and 79°F (26°C) in summer.

The central parts of the country have a continental climate, being both warmer and drier than the north. Winter temperatures in this region average around 43°F (6°C), with frost and occasional snowfall. Summers average a pleasant 82°F (28°C).

The huge Saharan area has a desert climate with sweltering summer temperatures that turn incredibly cold during winter nights. Temperatures range from 14°F–93°F  (-10°C–34°C) and oppressive highs of 120°F (49°C) aren't uncommon. The area also suffers from frequent and violent winds.

Algeria is frequently hit with heat waves during the summer months. Expats should stay out of the sun and ensure they are hydrated during the day.
