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

About 5 of every 1,000 people in Ilocos Norte lived below the poverty line in 2023 (0.5%)[26]

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

Government & Leaders

A governor leads Ilocos Norte. Its local laws, called ordinances, are passed by the Sangguniang Panlalawigan (the provincial board), led by the vice governor. The governor, the vice governor and the board's elected members serve three-year terms, and none may serve more than three in a row.[20, 21]

History & Identity

Ilocos Norte's fiesta and days

Everything listed for Ilocos Norte in Now

Created
Created by a royal decree of 2 February 1818 that divided the Province of Ilocos, as Proclamation No. 463 (2018) records; its civil government was set up under Act No. 207, enacted 20 August 1901[9, 10, 11]

How it got its name

Local traditionA history of Ilocos Sur says the coastal plains from Bangui, in Ilocos Norte, south to Namacpacan were known as the Ylokos, and their people as Ylocos, meaning "from the lowlands"; the Spaniards later called the region Ylocos or Ilocos, and its people Ilocanos.[13]

A royal decree of 2 February 1818 divided Ilocos in two, and its northern part became Ilocos Norte.[9, 10]

Its story

Augustinian friars founded the parish of Laoag in 1580, and Augustinian missionaries that of Paoay in 1593. The cornerstone of the church of Paoay was laid in 1704.[14]

In 1661 the chieftain Almazan looted the church of Laoag, took possession of the Virgin Mary's crown and proclaimed himself king.[14]

On 2 February 1818, under Governor-General Mariano Fernández de Folgueras, a royal decree made the north of Ilocos a province of its own. The province keeps the day as its founding anniversary: its bicentennial year opened on 2 February 2018, and the 208th anniversary fell in 2026.[9, 10, 15, 16]

Laoag stayed the capital under American rule. Act No. 207 extended the Provincial Government Act to Ilocos Norte on 20 August 1901, and in 1903 its fifteen towns were merged into ten.[11, 17, 18]

When Japanese forces reached Laoag on 12 December 1941, Governor Roque Ablan left the capitol, built from 1917 to 1925, and carried on the provincial government from the mountains of Maananteng, in Solsona. The 15th Infantry of the United States Army Forces in the Philippines, Northern Luzon, retook the capitol on 13 February 1945.[19]
