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[35]

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 95 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

Created
Made a province by Republic Act No. 6394, approved and in effect 10 September 1971, which separated it from Nueva Vizcaya; a sub-province of Nueva Vizcaya from 18 June 1966 under Republic Act No. 4734[9, 10]

How it got its name

It is named in honour of President Elpidio Quirino.[10, 11]

Its story

Its first towns, Aglipay, Diffun and Maddela, were created by an executive order of 11 November 1950, and Saguday followed in 1959.[11]

Republic Act No. 4734 of 18 June 1966 made those four towns the Sub-province of Quirino, within Nueva Vizcaya, and Jose B. Aquino was elected its first lieutenant governor in 1967. In 1969 Republic Act No. 5554 created the town of Cabarroguis as its capital, named in honour of Congressman Leon Cabarroguis.[10, 11, 12]

Republic Act No. 6394 of 10 September 1971 separated Quirino from Nueva Vizcaya as a province of its own, with Cabarroguis as its capital. Its first elected provincial and town officials took office on 10 February 1972, the date the province's history gives for its formal establishment.[9, 11]

The province keeps 10 September, the day of that law, as its founding anniversary, Araw ng Quirino, with the Panagdadapun Festival, from the Ilocano for gathering; the 54th fell in 2025. In 1983 the town of Nagtipunan was carved out of Maddela.[13, 14, 15, 16]
