What to expect in Niterói in January

Myllena Vieira, editor at Visite
Editor's tip

January finds Niterói in the middle of summer. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Highs reach 30 °C (86 °F): the heat calls for early starts, sunscreen, and spending the middle of the day in the shade or in the water. 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.
