What to expect in Mariana in January

Myllena Vieira, editor at Visite
Editor's tip

January finds Mariana in the middle of summer. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 29 °C (84 °F) and nights that still call for a light jacket. It is one of the busiest times of the year: the destination fills up, rates go up and the best hotels sell out early. Book ahead or choose weekdays. It rains fairly often, so keep an indoor plan handy for gray days.
