Where to go?
The high season in Europe is ending, but the weather is still favorable, especially in the Mediterranean countries. In Asia, the monsoon season is ending and, although there is still a risk of typhoons, it is possible to travel to many areas of China or Indonesia without getting soaked. The north of Africa has no longer those scorching temperatures of August, and in Zimbabwe and Namibia they are enjoying their dry winter period, sunny and with pleasant temperatures. The least recommended places to visit in September are the Caribbean, Central America and some areas of Asia, since there is the hurricane season.
