Ubatuba is humorously referred by Paulistas
as "Ubachuva" (chuva
means rain in Portuguese) due to the good chance of raining when they get
there. In reality, this reputation is likely due to the city being most visited
between December and March (the summer), which coincides with the the rainy
season. Winter months (between June and August) have little rain, but the
average temperature goes below 20°C. However, there is usually plenty of
sunshine hours year-round
