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 II[35]

No dry season. The rain is heaviest from December to February, and no month is truly dry.

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

Life & Economy

About 18 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
18.1% of people[23]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 18 of every 100 people in Casiguran lived below the poverty line in 2021 (18.1%)[23]

The PSA's model for every town puts it between 14.0% and 22.2%, with 90% confidence.

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

History & Identity

How it got its name

Local traditionThe town's history page gives a folk legend that Casiguran comes from kasiguruhan, meaning safety or assurance, because the bay sheltered ships in storms.[10]

Its story

Casiguran was one of the four municipalities of the Subprovince of Aurora created in 1951.[12]

Barrios of Casiguran became the Municipal District of Dilasag in 1959 and the Municipal District of Dinalongan in 1966.[13, 14]
