Cuiab (Portuguese pronunciation: [kujaba]) is the capital city of the Brazilian state of Mato Grosso. It is located near the geographical centre of South America.

As in almost all regions of Brazil, the seasons in Cuiaba are opposite of those we know in Central Europe. Due to its location in the southern hemisphere, summer lasts from December to February and winter is from June to August. However, the seasons are not very pronounced and the temperatures vary only slightly.
