San Dionisio, officially the Municipality of San Dionisio, is a 4th class municipality in the province of Iloilo, Philippines. According to the 2015 census, it has a population of 38,775 people.[3]

San Dionisio is 106 kilometres (66 mi) from Iloilo City and is 91 kilometres (57 mi) from Roxas City. Quiniluban Island, Tago Island and Igbon Island, known for coral reef scuba diving and ecotourism, lie in the east across the Concepcion bay.


During the Spanish Colonization of Philippines, a native leader named "Dionisio" had cleared the forest land to create a settlement called "Lakdayan". In 1877 Spanish arrived and renamed "Lakdayan" to "Dionisio" in the honor of humble fisherman founder of the settlement. Spanish converted the natives and appointed St. Vincent Ferrer as Patron Saint of the settlement. Spanish set up the municipality at Concepcion, of which Dioniso was a part of. During Spanish times, the head of the local government of Concepcion was titled "Kapitan" (captain) and the subordinate leaders in San Dionisio were titled "Tenientes" (lieutenant) and hereditary Cabeza de Barangay (head of barangay). Eventually Sara was carved out of Concepcion to establish an eponymous municipality, which also included Dionisio as one of the constituent barangay of Sara. In 1920, San Dionisio municipality was established after carving it out of Sara municipality.


San Dionisio has intermediate tropical climate, relatively dry from December to April and wet for the rest of the year. Northeast monsoon and trade winds cause the dry and sunny weather. Southeast monsoons and cyclone storms cause the wet and stormy conditions. January is the coldest month during the relatively cool tropical period from December to February. April to June summer season has the warmest temperature. High tropical temperature and the sea on eastern side cause the high relative humidity.
