Basic Information about Kaduna: Geography, Postal Code, Weather

Kaduna is a city in Nigeria situated on latitude 100.36 North and 070.28 East. Kaduna postal code is 800001 but varies in different areas of Kaduna. Kaduna, on the whole, has a flat low-lying country. It is on the southern margin of the Northern Plateau and occupies a fairly central position of the then Northern region. It lies close to River Kaduna and like Nigeria, which derived its name from the river Niger; it is generally believed that Kaduna also derived its present name from river Kaduna. The location of Kaduna was unique and distanced from all other big towns like Zaria, Kagoro, Kafanchan, and Lere, which are within the state, and Jos, Abuja and Minna in the neighbouring states. For example, the distance between Kaduna and the nearest Zaria city is 80.60 kilometres or 50.1 miles away, from Kaduna to Abuja 216.96 Kilometers or 96.6miles and from Minna is 169 kilometres or 105 miles by road.
Kaduna regional topography consists of a rolling park-like terrain with little relief situated about one hundred feet above and below the 2,000 feet contour line. It has a mean maximum temperature of 900 F and during the wet season, it receives some 40-60 inches of rain, which rises to a peak from July to September. The climatic condition during the dry season from November to March is a dusty laden harmattan wind, which is dry, cold and often strong. It blows from the north-east and straight to the Sahara regions. On the arrival of the first rains in April, the prevailing wind veers the south-west and continues from May to October from that quarter.
The soil over the Kaduna area are general to the northern plains and are at laterite formed from drift deposits which mantle the solid sedimentary and precambrian basement (granite) rocks, Kaduna lies within what is known as the “Zaria” soil group where the covering material may be up to 14feet in depth. Being of the texture this soil is relatively different to work because it tends to become waterlogged with heavy rain and to dry out and crack during the dry season. This has favoured the growth of cotton in Zaria Province, and cotton harnessed to the water resources of the Kaduna River.
The region is well drained by two tributary rivers of the Niger, namely Kaduna and Gurara. Other tributary rivers along the plains are Galma, Saye, Kubani, Tubo, Mariga, Dhika, Kinkiba and Sarkin Pawa River. Though the plains have a long severe dry season, from November-March, the growing period within the rainy season is sufficiently wet and receives enough radiation for the benefit of a wide range of crops. This is besides the fact that the Kaduna River, unlike most rivers in northern Nigeria is a perennial stream, though subject to great season fluctuations in water level, it provided an inexhaustible water supply and served as cheap means of transportation in pre-colonial northern Nigeria. Furthermore, the existence of the river was an important factor that sustained the earlier settlement in the vicinity of Kaduna such as Barnawa, Makera and Kurmin Mashi, which is along its banks.
