Founded in the 19th centuary by slavetraders as a zariba, a small fortified base, it grew into an administrative centre during British rule. The city is not dominated by a single ethic group; instead, its position as a commercial hub has drawn many different peoples from around the country. Over the last two decades, Wau has nearly doubled in size, from 84,000 in 1993 to 151,000 today.
Temperatures stay in the mid-30s during most of the year. The dry season lasts from November to March, while the summer months see an increase in rainfall.
Flights are handeld by Wau Airport (IATA: WUU), a small airport with a single un-paved runway located northeast of city centre. They newly funded national carrier Southern Sudan Airlines  is planning on starting services from Juba.
Wau is also the terminus of the narrow gauge railway from Khartoum, however due to the newly independence of South Sudan all trains have stopped running and there are no news on when they will resume.
Several roads intersect here, A43 connects with Juba and Rumbek while A44 runs southwest towards Tumbura near the border with Central African Republic and Democratic Republic of the Congo. B41 heads northwest towards Raga and ultimately Nyala. Notice that all roads are in poor condition and can sometimes be nothing more than a dirt track. Driving with regular cars is highly unadvisable.
Wau has few attractions to see, wild hippos in the Jur river is however quite a sight and can be seen at times.
