Weather in Brazil
Climate
The climate of Brazil comprises a wide range of weather conditions across a large geographic scale and varied topography, but the largest part of the country is tropical and covered by the Amazon Rainforest.
Brazil hosts five major climatic subtypes: equatorial, tropical, semiarid, highland tropical, and temperate; ranging from equatorial rainforests in the north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil. Many regions have starkly different microclimates.
A equatorial climate characterizes much of northern Brazil. There is no real dry season but there are some variations in the period of the year when most rain falls. Temperatures average 25 °C), with more significant temperature variations between night and day than between seasons.
Over central Brazil rainfall is more seasonal, characteristic of a savanna climate. This region is as large and extensive as the Amazon basin but, lying farther south and being at a moderate altitude, it has a very different climate. In the interior Northeast, seasonal rainfall is even more extreme.
The semiarid climate region receives less than 800 millimetres of rain, which falls in a period of two or three months. From the south of Bahía, near São Paulo, the distribution of rainfall changes, here some appreciable rainfall occurs in all months.
The South has temperate conditions, with average temperatures below 18 °C and cool winters, frosts are quite common, with occasional snowfalls in the higher areas.
