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[36]

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.

Covers about 56 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

Iloilo's economy made ₱286.7 billion of goods and services in 2025, ₱134,957 for each person. About 18 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

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
17.7% of people[24]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

About 18 of every 100 people in Iloilo lived below the poverty line in 2023 (17.7%)[24]

The PSA's survey puts it between 14.5% and 21.0%, with 95% confidence. The poverty line was ₱33,374 a person for the year. As the PSA counts it, without the City of Iloilo.

History & Identity

Iloilo's fiesta and days

Everything listed for Iloilo in Now

Created
Organized by the Spaniards as the Alcaldía de Panay, with Oton as its capital, in 1569; its civil government was set up under Act No. 113, enacted 11 April 1901[9, 10]

How it got its name

Local traditionThe province takes its name from Irong-Irong, the old name of the city of Iloilo: a tongue of land, shaped like a nose, south of the Iloilo River.[11, 12]

Its story

Local traditionThe Maragtas legend tells of Datu Puti and other datus who fled the tyranny of Sultan Makatunao of Borneo in the 13th century and landed at the mouth of the river at today's San Joaquin; Datu Paiburong was given Irong-Irong.[11, 12]

The Spaniards first organized it in 1569 as the Alcaldía de Panay, with Oton as its capital, later called the Province of Oton. The capital moved to Arevalo in 1582 and, in 1790, to the town of Iloilo, after which the province was called Iloilo. Capiz was carved from it in 1716.[9]

Sources differAntique was carved from it too, but the sources differ on the year: Iloilo's history and an Antique page of 2010 give 1796, and two national historical markers 1790.[9, 13, 14, 15]

Iloilo was opened to world trade in 1855.[11]

The revolution reached Panay in October 1898, led by General Martín Delgado, who freed every town but Iloilo, Molo and Jaro. American forces reached Iloilo's port on 28 December 1898, and Delgado's forces surrendered in February 1901.[9, 11]

On 11 April 1901 the Americans set up the civil government of Iloilo, with its capital at Iloilo and Delgado as its first governor. The province has kept 11 April as Kaadlawan sang Iloilo since 1977; the exact date of its Spanish founding, it notes, cannot be found in any surviving record.[9, 10]

In 1936 Commonwealth Act No. 158 created the City of Iloilo, inaugurated in 1937, and in 1966 the island of Guimaras became a sub-province, the beginning of today's Province of Guimaras.[11, 16, 17]
