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 I[31]

Two seasons: dry from November to April, wet for the rest of the year, with the heaviest rain from June to September.

Life & Economy

About 16 of every 100 people lived below the poverty line in 2021.
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
15.9% of people[19]Below the poverty line, by the PSA's estimate for every town.
Income classIncome classThe Department of Finance sorts provinces, cities and municipalities into classes by their average yearly income over recent years: 1st class has the most. It measures the local government's income, not how well off its people are.More in the glossary
1st class[4]
About 16 of every 100 people in Santa Lucia lived below the poverty line in 2021 (15.9%)[19]

The PSA's model for every town puts it between 13.5% and 18.3%, with 90% confidence.

Created
The town's history page says Santa Lucia, then called Kaog or Dumangague, was founded in June 1572 by Juan de Salcedo, and that its first mission was set up on 5 January 1586.[9]

Its story

According to the town's own history, Captain Juan de Salcedo reached the place, then called Dumangague, probably in June 1572 and found many people living there.[9]

On 5 January 1586 Augustinian friars set up the ministry of Santa Lucia, and the image of Saint Lucy came from Mexico. The Augustinians built the church the same year.[9]

The church was rebuilt completely in 1887 by two friars and renovated in 1936. The 1990 earthquake toppled its belfry, and it was repaired in 1991.[9]

During the Philippine Revolution, General Manuel Tinio made the old convent next to the church his headquarters. Local Katipuneros fought at Balidbid in 1898, and in 1899 they raided the American garrison in Salcedo.[9]

A civilian government was set up in 1901. Under the Japanese, part of the poblacion was burned, and on 21 February 1942 American USAFE officers held a mass induction at Nagtablaan.[9]
