Summer temperatures are high throughout the country, particularly in the south where it is both very dry and very hot. During this time, road travel is difficult and air travel prone to delay because of sandstorms. Northern cities have high humidity, while those along the coast are cooled by sea breezes. In the winter, the oases of the far south are pleasant and attract many visitors. The desert temperature drops dramatically at night. North of the Sahara, temperatures are very mild from September to May and vary little between day and night. South of the Sahara, temperatures are pleasant from October to April, but there are great variations between day and night. Coastal towns are prone to storms from the sea. Rainfall is relatively low throughout the country and in the far south it is virtually unknown.

Cotton and linen lightweights for winter months and for evenings in desert areas. Woollens and light rainwear are advised for the winter along the coast and the Hauts Plateaux. South of the Sahara, from mid-December to mid-January, temperatures drop and warm clothes are necessary both in the morning and the evening. A mountain sleeping bag is also required when camping.

Algeria is situated along the North African coast, bordered to the east by Tunisia and Libya, to the southeast by Niger, to the southwest by Mali, and to the west by Mauritania and Morocco. It is Africa’s second-largest country, with 1200km (750 miles) of coastline. Along the coastal strip are the main towns, fertile land, beach resorts and 90 per cent of the population. Further south lies the area of the Hauts Plateaux, mountains of up to 2000m (6600ft) covered in cedar, pine and cypress forests with broad arable plains dividing the plateaux. The remaining 85 per cent of the country is the Sahara Desert in its various forms, sustaining only 500,000 people, many of whom are nomadic tribes with goat and camel herds. The oil and minerals boom has created new industrial centres like Hassi Messaoud, which have grown up within previously barely inhabited regions of the northern Sahara. The plains of gravel and sand in the deep south are interrupted by two mountain ranges: the dramatic Hoggar massif, rising to almost 3000m (9800ft), and the Tassili N’Ajjer or ‘Plateau of Chasms’. Both have long been important centres of Tuareg culture.
