The months of December, January and February tend to revolve around the traditional southern hemisphere summer events such as Christmas, New Year (Réveillon) and Carnival. The official Réveillon party takes place on Praia de Icaraí, one of the most famous beaches in Niterói. On this beach, for three days people anticipate and get ready to party for the big day, and over this pre-Réveillon atmosphere there are several musical performances, from Rock to Samba, while fireworks are tested.

July brings with it the winter festival, which includes a wealth of action sports events such as the skateboarding championship, at the São Francisco Beach marina, and the paragliding tournament, at parque da cidade, on top of morro da viração. The newest addition to the festival is the Stand-Up Paddle Jurujuba-Icaraí crossing, which is a nod to the growing popularity of this new twist on surfing.
