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[20]

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 80 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.

History & Identity

Official name
Region II (Cagayan Valley)[4]
Created
Region II, called the Cagayan Valley Region, was one of the eleven uniform regions of the Integrated Reorganization Plan, which Presidential Decree No. 1 adopted on 24 September 1972.[8, 9, 10]

Its story

The Cagayan Valley Region was set up in 1972 as Region II among the eleven regions of the Integrated Reorganization Plan.[8, 9]

According to a 1975 decree, it consists of Kalinga-Apayao, Ifugao, Quirino, Nueva Vizcaya, Isabela, Cagayan and Batanes, centered on Tuguegarao, Cagayan.[10]

On 1 April 1974 President Marcos set up a task force at presidential level to develop the Cagayan Valley in an integrated way, noting that the area had natural wealth going unused and was troubled by armed conflict.[11]

A 1981 order still lists Region II as the same seven provinces with its center at Tuguegarao.[12]

In 1987 Ifugao and Kalinga-Apayao left Region II to join the new Cordillera Administrative Region.[13]
