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[32]

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

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.

History & Identity

Created
Casiguran took legal existence as a town, a daughter of Albay, in 1800 according to the provincial timeline; no decree is named.[9]

How it got its name

Local traditionThe provincial page says the name comes from the local term casi-gurang, 'mostly aged', because it was the first parish and therefore the oldest, and that elderly folk are also said to have made up most of its people.[10]

Its story

The provincial government's page calls Casiguran the first settlement established by the Spaniards in the province and the centre of Christianization work in southern Bicol.[10]

Until 1817 Juban was a barrio of Casiguran, and in that year it was set up as its own parish.[11]

In 1852 Magallanes, originally named Parena, was set up as a barrio under Casiguran.[11]

Casiguran assumed legal existence as a town in 1800.[9]

In 1978 a jar burial site was excavated in barangay Escuela, with earthenware of volcanic tuff and clay.[12]
