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 93 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 separate politico-military province by Governor-General Luis Lardizábal's order of 24 May 1839, approved by a royal decree of 10 April 1841; its civil government was set up under Act No. 337, enacted 28 January 1902, with Bayombong as its capital[9, 10, 11]

How it got its name

Its own account says the province was named after the people of Vizcaya, or Biscay, on the Basque coast of Spain.[9]

Its story

Early in the 19th century its lands belonged to the vast mission territory governed from Cagayan, which ran from Nueva Ecija to Aparri.[9]

On 24 May 1839 Governor-General Luis Lardizábal, on the advice of the alcalde mayor of Cagayan, ordered Nueva Vizcaya made a politico-military province of its own, and a royal decree of 10 April 1841 approved it; Pedro Menchaca was its first governor. The new Province of Isabela took much of its north in 1856.[9, 12]

Spanish rule ended when revolutionary forces reached Bayombong in August 1898. The Philippine Commission set up its civil government by Act No. 337 of 28 January 1902, with Bayombong as its capital.[9, 11]

Act No. 1876 of 1908 made the former comandancia of Quiangan the sub-province of Ifugao, which took the province's northwest, and added to Nueva Vizcaya the lands of the Ibilao people in the old Spanish comandancia of Binatangan. In 1971 its sub-province of Quirino became a province of its own.[9, 13, 14]

A proclamation of April 1985 made 10 April, the date of the royal decree, Nueva Vizcaya Day; at the provincial board's request it was moved that May to 24 May, the day the province keeps as its founding anniversary, celebrated with the Grand Ammungan Festival. The 187th fell in 2026.[10, 15, 16]
