The temperature in the Natural Park of Ubajara is between 18 and 23 degrees Celsius. The area may get cold during the rainy season. If you are planning a trek excursion, you'd better bring a pullover or a light jacket. Trekking boots are indispensable.
In the park there are some nice waterfalls you should not miss: Cachoeira Bica da Gameleira, which gives access to three more waterfalls; Cachoeira Bica do Gavião, and Cachoeira Bica da Murimbeca, which can be seen from the cable car.
