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[34]

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.

History & Identity

Official name
City of Santiago[4]
Created
Santiago became an independent component city under Republic Act No. 7720, approved 5 May 1994, which converted the Municipality of Santiago into the City of Santiago. The Act says the city gains corporate existence once voters ratify it in a plebiscite held within 60 days.[9]

How it got its name

The town was first named Carig; Santiago is its later name. The sources read do not say why the name Santiago was chosen.[10]

Its story

The settlement was first called Carig. In 1903 the Philippine Commission merged the municipalities of Carig and Cordon into Echague as part of cutting Isabela from fifteen municipalities to eleven.[11]

By 1917 the Revised Administrative Code lists Santiago as a municipality of Isabela.[12]

In 1946 Executive Order No. 97 took barrios and sitios out of the municipality of Santiago to form the new municipality of San Mateo.[13]

Santiago was made an independent component city in 1994 under Republic Act No. 7720, ahead of Cauayan in 2001 and Ilagan in 2012.[9, 14]
