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 IV^[38]

Rain spread fairly evenly through the year, with no dry season.

Covers about 91 of every 100 parts of its land. Read by Scene off PAGASA's climate map, so approximate: the type that covers most of the place's land.

Life & Economy

Isabela City's economy made ₱15.3 billion of goods and services in 2025, ₱102,542 for each person. About 16 of every 100 people lived below the poverty line in 2023.

Economy, 2025Gross domestic productThe value of all the goods and services made in a place in a year: the size of its economy. The PSA measures it for every region, province and highly urbanized city. Counted at 2018 prices, it leaves out the rise in prices, so one year can be set beside another.More in the glossary: ₱15.3 billion^[22]Its gross domestic product at current prices; ₱12.7 billion at 2018 prices.

For each person, 2025: ₱102,542^[24]Its economy divided by its projected population, at current prices, as the PSA works it out.
Poverty, 2023Poverty 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: 16.0% of people^[25]Below the poverty line, by the PSA's survey.
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^[5]

About 16 of every 100 people in Isabela City lived below the poverty line in 2023 (16.0%)^[25]

The PSA's survey puts it between 10.5% and 21.6%, with 95% confidence. The poverty line was ₱29,770 a person for the year.

The PSA notes: Those with CVs higher than 10% in 2023 poverty incidence among population should be used with caution.

Government & Leaders

A mayor leads Isabela City. Its local laws, called ordinances, are passed by the Sangguniang Panlungsod (the city council), led by the vice mayor. The mayor, the vice mayor and the council's elected members serve three-year terms, and none may serve more than three in a row.^{[17, 18]}

City classCity classA highly urbanized city or an independent component city governs itself apart from the province around it: its voters do not elect the governor. A component city is part of its province.More in the glossary: Component city^[5]

Legislative districtLegislative districtThe area that elects one member of the House of Representatives. A big province or city may have several.More in the glossary: Lone district of Basilan^{[20, 21]}

Everything listed for Isabela City in Now

Official name: City of Isabela^[5]
Created: Republic Act No. 9023, approved on March 5, 2001, converted the Municipality of Isabela in Basilan into a component city, the City of Isabela. The Act made the city's corporate existence depend on a plebiscite in the municipality, which the city's own history page says took place on April 25, 2001.^{[10, 11]}

How it got its name

Before Spanish rule the natives of Basilan knew the place as Pasangan or Pasangen, meaning market, and later as a multi-ethnic settlement called Pagpasalan.^[11]

The Spanish fort built there in 1845 was named for Isabela II, Queen of Spain, and the settlement took the name Isabela de Basilan.^[11]

Its story

The Spaniards occupied the place in 1844 and built a fort in 1845, first of wood and in 1848 of stone.^[11]

The fort served as the Spanish fleet's naval headquarters in the 19th century, and Malamawi Island was used to store coal for ships.^[11]

Republic Act No. 288, approved on June 16, 1948, created the City of Basilan from the whole island, including the former municipality of Isabela, separating it from Zamboanga City.^[13]

Presidential Decree No. 356 of December 27, 1973 made the island a province, with the town proper of Isabela kept as the City of Basilan.^[14]

Presidential Decree No. 840 of December 11, 1975 abolished the City of Basilan and made Isabela a municipality covering the former city and the former municipality of Malamawi, with the capital of Basilan in Isabela.^[15]

Republic Act No. 9023 of March 5, 2001 made Isabela a component city.^[10]
