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^[30]

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.

Life & Economy

About 10 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: 9.9% of people^[18]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: 3rd class^[4]

About 10 of every 100 people in Piat lived below the poverty line in 2021 (9.9%)^[18]

The PSA's model for every town puts it between 7.6% and 12.2%, with 90% confidence.

The PSA rates this estimate's reliability as acceptable rather than high: read it as a guide.

Its story

Piat is famous for its image of Our Lady of Piat, which the Dominican historian Aduarte said came from Macao to Cagayan around 1600, probably through Bishop Soria and the 1604 mission.^[9]

When the people of Piat protested the image's removal, it was returned and set in a chapel between Piat and Tuao. The chapel was opened on 26 December 1623.^[9]

In 1903 the Philippine Commission kept Piat as a municipality within its present boundaries.^[10]

Timeline
