Temperature: Celsius x Fahrenheit

Amazon Basin region (1)


 Equatorial climate.  Plenty of rain and humidity.


Northeastern Coastlands (2)


 From Fortaleza to the Bahian south coast,
 with an all year round travel climate pattern.


Rio,Vitoria and Sao Paulo coast (3)


Hybrid pattern.


South States Region (4)


Temperate four season climate pattern.


Inland Plateau (5)


From the northeast inland to the Pantanal,
 with a hard dry season and more extreme temperatures.




The map above shows the rough configuration
 of these five climatic regions.
 Obviously, there are transitional zones and some
 significant variations within each climate region.






Seasons in Brazil are the reverse of those of Europe and United States: 


Spring: 22nd September - 21st December
Summer: 22nd December - 21st March
Autumn: 22nd March - 21st June
Winter: 22nd June - 21st September




But you should not deduce too much from this division.
 Truly, this four season pattern is only applicable to southern Brazil.
 Most of Brazil territory shares a two-season pattern:
 a rainy season (the summer) and a non-rainy one (the winter). 




And it is most the rain – not the cold 
that you should equate if your destination
 is some places in the Northeast or the Amazon.
