Geography of Brazil latitude), which crosses the country at the latitude of the city of São Paulo. Brazil has five climatic regions: equatorial, tropical, semiarid, highland tropical, and subtropical. Temperatures along the equator are high, averaging above , but not reaching the summer extremes of up to in the temperate zones. There is little seasonal variation near the equator, although at times it can get cool enough for wearing a jacket, especially in the rain. At the country's other extreme, there are frosts south of the Tropic of Capricorn during the winter (June–August), and there is snow in the mountainous areas, such as
North African climate cycles latitude of the tropics. The latitudinal extent of the tropics is roughly defined by the maximum wandering path of the thermal equator. An area that today is located between the Tropic of Capricorn and the Tropic of Cancer. However, as the obliquity changes, the overall wandering path of the thermal equator shifts between 22.2° and 24.5° north and south. This wandering may affect the positioning of the North African Summer Monsoon Front and thus impact the perceived strength of the North African Monsoon. Further confirmation of the impacts of obliquity on the North African Monsoonal have been provided through a
