Tramandaí, Brazil

The population is just 20,130 in this sleepy coastal town, so don't expect a bustling metropolis. Summers are warm at 22°C on average, but winters can get quite chilly at 14°C. And bureaucracy is a persistent headache, as Tramandaí only separated from the neighboring city of Imbé in 1988 when many small municipalities were carved out across the state.

If you're after a slow-paced, low-key beach lifestyle, Tramandaí could be a good fit. But those seeking an energetic urban center or temperate year-round climate would do better to look elsewhere.
