Algeria Weather, climate and geography
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 are best 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. Remember that desert temperatures can drop very low during the night, so don’t get caught out with only flimsy layers. 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.
