Detailed geography
Physical Features
- Terrain
- mostly high plateau and desert; some mountains; narrow, discontinuous coastal plain
- Climate
- In Algeria the climate varies. Coastal areas, including Algiers, are hot in summer and chilly and rainy for several months in winter. Inland mountain regions between the coast and the desert have cooler weather; temperatures are below freezing for long periods of winter. Spring and fall in the "Tell" (a part of northern Algeria in which the average annual rainfall is 16 inches or more, making it usable for agriculture), are mild and enjoyable. The Tell and the Sahara have climate extremes, although in different ways. The Tell is very cold in winter and very hot in summer. The Sahara’s extremes are between daytime (warm in winter; hot in late spring, summer, early fall) and nighttime (cold year round). Algiers has four distinct seasons, with temperature variations ranging normally between 40-110 degrees Fahrenheit. It tends to be extremely hot during the month of August, and some winters can be cold and rainy. In general, however, the weather is quite pleasant, but mold and mildew can be a real problem. Despite its warm summer, Algiers has what is often described as a "cold climate with a hot sun." Winter temperatures rarely fall below freezing. Cool weather generally begins in November and lasts into March. The rainy season spans about five months.
