Zambia is in Southern Africa. Roughly the size of Texas or France, Zambia is a landlocked country, bordered by Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, a narrow strip of Namibia known as the Caprivi Strip to the southwest, Angola to the west, and the Democratic Republic of the Congo to the northwest.Zambia offers travelers some of the world's best safari opportunities, a glimpse into "real Africa," and Victoria Falls, one of the World's Seven Natural Wonders and a UNESCO World Heritage Site.
As can be seen even from the bizarre squashed-peanut shape of the country, Zambia is one of the stranger legacies of colonialism, agglomerating a large number of different tribes (73, according to the official count) and languages (20, plus dialects). Fortunately, with a long history of coexistence, significant migration around the country and similar Bantu-family languages, they all seem to get along pretty well and Zambia has been spared the violent intertribal strife that has decimated countries like Rwanda.
If you look at a map, Zambia appears to be squarely in the tropics, but thanks to its landlocked and elevated position it does have distinct seasons that run as follows:
Dry season — May to August. The coolest time of the year, with temperatures 24-28°C during the day, can drop as low as 7°C at night. Probably the best time of year to visit Zambia: come early in the dry season for birdwatching or to see Vic Falls at their biggest, or later when the bush has dried up for good game-spotting on safari.
Hot season — September to November. Temperatures rocket up to a scorching 38-42°C and clouds of swirling dust make driving on dirt roads an asthmatic's nightmare. If you can take the heat, though, it's a good time for safaris as wildlife clusters around the few remaining watering holes.
Wet season — December to April. Temperatures cool down to 32°C or so and, true to the name, there is a lot of rain — sometimes just an hour or two, sometimes for days on end. Unsealed roads become impassable muddy nightmares, and many safari lodges close.
All temperatures above are given for the lowland valleys that house most of Zambia's population and national parks. If you're heading up to the plateaus, temperatures will be around 5°C lower.
