The climate is humid subtropical (Köppen: "Cfa"), a type found in Southeastern Australia (very homogeneous to Sydney, albeit cloudier and wetter), without major temperature deviations as found in Brunswick and Savannah, Georgia (but still considered very high by Brazilian standards), due to the continentality and polar vortex position in the southern American cities. Summers are warm to hot with regular rainfall. Winters are cool with episodic frosts (about 24 per year) and fog, with no noticeable difference in the amount of monthly rainfall.
