What is it about quiet São Jacinto that attracts returning visitors year-round? One answer is the weather. Aveiro's beach outpost on the Atlantic sits exposed to the elements on a peninsula that shields the Ria de Aveiro lagoon from the open sea. Still, the weather remains primarily mild and sunny, with an occasional stiff breeze or rain shower during the winter. In São Jacinto, you get a front seat to the seasons and their changes. Sometimes, all of them in one day.
