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 I[30]

Two seasons: dry from November to April, wet for the rest of the year, with the heaviest rain from June to September.

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
18.3% 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 18 of every 100 people in Sigay lived below the poverty line in 2021 (18.3%)[18]

The PSA's model for every town puts it between 10.8% and 25.7%, with 90% confidence.

The PSA says caution must be observed in using this estimate: read it as a rough guide only.

History & Identity

How it got its name

Local traditionOral tradition says the name is the Ilocano word for fish trap. In the tale, a woman carrying mudfish from Lake Ban-ao was asked by a Spaniard where she got them, and answered with the name of her trap.[10]

Local traditionA second tale says hunters of the village's tribes made a big net like a fish trap for hunting in the mountains, and lowlanders who visited came to call the place Sigay.[10]

Its story

The town's page says people claim Sigay is as old as any Spanish-era place in the province, but no written records of its early history have been found.[10]

The first settlers were Igorots from the Mountain Province who intermarried with Ilocanos; their descendants are called the Bago, and their Christian baptisms began around 1700.[10]

The page says Spain recognised Sigay as a municipal district in the 1800s, and that it became a full municipality in 1960 after its first local elections on 12 November 1959.[10]
