Viamão, Brazil

With a population of 169,176, Viamão is the largest municipality in the Porto Alegre metro region. But this historic cattle town comes with some serious trade-offs for those considering a move. The weather can be oppressively humid, with frigid winters and scorching summers that even the famous explorer Augustin Saint-Hilaire described as unlivable. And while Viamão boasts natural beauty in its parks, the ever-encroaching population has put a strain on the environment. Overall, this is a place better suited for hardy locals than foreign transplants seeking an easy life.
