Salinópolis, a brazilian city at Pará state, is an example of a coastal area under unorganized development with social and environmental impacts. Tourist activity in the city leads to an unsustainable development and an aggressive exploration of the local resources due to its high seasonality. Despite the region potentiality, tourism is based only on beach use for recreation. The main goal of this study is to understand the natural dynamic of the system (wind, rain and waves season and morphological changes) in order to provide a better development strategy of tourist activities for the region of Salinópolis - PA. Results show that wave climate has a seasonal variation with higher waves in the first semester. This condition is favorable for surf practice. Wind intensity is higher during the last semester and coincides with the dry season. Wind direction is parallel to the coast, the perfect condition for windsurfing, kitesurfing and sailing. Wind direction knowledge also permits the development of a better design for the mangrove walkway at Ma¸carico beach. A walkway parallel to the main wind direction would improve airing at the city center. Mangrove walkways would act as an education tool for residents and tourists. Mangroves would also work as coastal protection near the secondary access where the erosion threatens the parking area. The installation of permeable dams allow the deposition of sediment to stop erosion.
