Climate

Climate typeClimate typePAGASA sorts the country's climate into four types by when the rain falls. Type I has a dry season from November to April and a wet one for the rest of the year; Type II has no dry season, with the most rain from December to February; Type III has a short dry season; Type IV has rain spread through the year.More in the glossary

Type III[29]

No clear rainiest time of year, and a short dry season of one to three months, in December to February or in March to May.

Poverty, 2021Poverty incidenceHow many of every 100 people live in families whose income is below the poverty line: what a person needs in a year for food and other basic needs, as the PSA sets it for each province. It is an estimate, from a survey or, for a town, a statistical model, so the PSA gives a range it is likely to fall in.More in the glossary
30.0% of people[17]Below the poverty line, by the PSA's estimate for every town.

History & Identity

How it got its name

Local traditionThe town's own history says natives living by the shore called the place Lakdayan, and that the Spaniards renamed it San Dionisio after the settlement's leader, a fisherman named Dionisio.[9]

Its story

The town history says San Dionisio was at first part of Concepcion, and later, when Sara split off from Concepcion, part of Sara.[9]

St. Vincent Ferrer is the town's patron saint, chosen by the Spaniards.[9]

Augustinian missionaries came two years after the Spaniards settled and built the first church from wood, bamboo and nipa shingles.[9]

Timeline

  1. 1877

    The town's history dates the arrival of the Spaniards, who found natives living near the shore at a place called Lakdayan, to 1877.[9]

  2. 1895

    The town history says the parish began in 1895 and that Rev. Fr. Casto Rosa served as its first priest.[9]

  3. 4 April 1903

    Act No. 719 cut the fifty-one municipalities of Iloilo province down to seventeen. It joined San Dionisio, with Ajuy, Lemery and Concepcion, to the municipality of Sara.[10]

  4. 1920

    In 1920 two town officials decided to dispatch Delfin Espino to Manila, with a request to the Secretariat of the Interior to make San Dionisio its own municipality, the town history says.[9]

  5. 1927

    According to the town history, the trip succeeded and San Dionisio became an independent municipality in 1927, with Espino appointed its first Municipal President.[9]

  6. 1956

    A papal order gave seven barangays of San Dionisio to the newly set up parish of Batad.[9]
