The climate of Tripoli and the northern coastal region is Mediterranean, with hot dry summers, cool winters and some modest rainfall.
Weather can be variable, influenced by the Sahara Desert and the Mediterranean Sea which moderates daily temperature ranges. The Sahara is basically very dry and hot in the summer and cool and dry in the winter.
Temperatures in the summer can reach 50C during the day but more commonly are around 40C. Night temperatures can vary from 30C to 40C. Some people have found travelling in summer rewarding, but most do not.
The best time for visiting the Sahara is probably from October to April, when temperatures range from 15C to 30C during the day and from 5C to 20C at night.
