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 IV[36]

Rain spread fairly evenly through the year, with no dry season.

Covers about 67 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
Created by Republic Act No. 711, approved and in effect 6 June 1952, which divided the Province of Zamboanga; the province keeps its founding anniversary on 17 September[9, 10, 11]

How it got its name

Local traditionThe province's own account derives Zamboanga from the Malay jambangan, a pot or place of flowers.[10, 12]

When Republic Act No. 711 divided the Province of Zamboanga in 1952, the southern part, with Pagadian, became Zamboanga del Sur.[9]

Its story

Its first people were the Subanon, who settled along the riverbanks; Muslim settlers followed: Maguindanao and Kalibugan farmers, Tausug, Sama and Badjao fishermen, and Maranao traders and artisans.[10]

Zamboanga was the capital of the American Moro Province, one of its five districts, and became a province in 1914. After the Second World War the provincial capital moved to Dipolog, and in 1948 Republic Act No. 286 created the town of Molave to be the capital.[10, 13, 14, 15]

Republic Act No. 711, in effect from its approval on 6 June 1952, divided the province, with Pagadian as the capital of Zamboanga del Sur, which began with eleven towns. The province keeps its founding anniversary on 17 September, counting from 1952; its 74th fell in 2026.[9, 10, 11, 16]

Pagadian, one of its two oldest towns with Margosatubig, both created on 23 December 1936, became a city on 21 June 1969.[10]

In 2001 the people of Zamboanga del Sur voted to make its Third Congressional District a new province, Zamboanga Sibugay, created under Republic Act No. 8973, leaving Zamboanga del Sur with 26 towns and the City of Pagadian.[10, 17]
