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.

Read by Scene off PAGASA's climate map, so approximate: the type that covers most of the place's land.

Life & Economy

About 36 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
35.6% 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
1st class[4]
About 36 of every 100 people in Cauayan lived below the poverty line in 2021 (35.6%)[18]

The PSA's model for every town puts it between 31.2% and 40.1%, with 90% confidence.

History & Identity

Its story

Act No. 716 of April 2, 1903 formed a new municipality of Cauayan from the barrio of Cauayan, then in the municipality of Isio, together with the rest of Isio and the municipality of Guijulngan (except the barrio of Dancalan). The seat was placed at the barrio of Cauayan.[9]

On November 20, 1948 two executive orders took barrios out of Cauayan to form the municipalities of Sipalay and Asia (now Hinoba-an).[10, 11]

Executive Order No. 314 of August 22, 1958 separated the barrio of Candoni from Cauayan to form the municipality of Candoni.[12]
