Because of its tropical and subtropical climate, Brazil is an all-year round destination. The Brazilian winter lasts for only three months from June to August. From December to February it's summer. The temperature varies within a year with monthly averages in winter between 13 and 18 degrees Celsius (55 and 64 degrees Fahrenheit). During the summer, temperatures can reach 30 to 40 degrees Celsius (86 to 104 degrees Fahrenheit) in Rio de Janeiro and into the regions in the south, but accompanied by frequent showers and a rather heavy humidity.
