What to expect in Ubatuba in December

Myllena Vieira, editor at Visite
Editor's tip

December finds Ubatuba 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. If the dates line up, it is worth fitting New Year's Eve in Ubatuba into your itinerary: it is what livens up the destination at that time of year.
