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[36]

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.

Read by Scene off PAGASA's climate map, so approximate: the type that covers most of the place's land.

A separate province from 1 January 1890, under a royal decree of 25 October 1889; its civil government was set up under Act No. 120, enacted 20 April 1901[9, 10, 11]

How it got its name

The Spaniards named the island Negros after the dark-skinned people they found there. The name already appears, as y de Negros, on an atlas drawn in 1545 by the Spanish cartographer Alonso de Santa Cruz.[9]

Sources differBefore the Spaniards, its people called the island Buglas, and the two Negros provinces explain the word differently: Negros Oriental's account names a tall grass like sugar cane that grew there in plenty, while Negros Occidental's reads it as an old word thought to mean cut off.[9, 10, 12, 13]

Its story

Under Legazpi, lands in its south, among them Tanjay and Dauin, were granted as encomiendas to Spaniards living in Cebu and Iloilo. In 1734 the island was given a military government of its own.[9]

The Governor General received a petition for Negros Oriental's separation from Negros Occidental, with Dumaguete proposed as capital. Under a royal decree of 25 October 1889, Governor General Valeriano Weyler made Negros Oriental a separate province on 1 January 1890, with 17 towns and Joaquin Tavera as its politico-military governor.[9]

In late 1898 rebels led by Diego de la Viña drove the Spaniards from its towns, and on 25 November 1898 a revolutionary provincial government was set up at Dumaguete, with Demetrio Larena as president.[9]

American forces occupied it in 1899. Act No. 120 of 20 April 1901 set up its civil government, which began on 1 May 1901, and on 28 August that year David S. Hibbard founded Silliman Institute, now Silliman University.[9, 11, 14]

It was joined with Negros Occidental in a Negros Island Region from 2015 until the order was revoked in 2017. Republic Act No. 12000 of 2024 set up the region again, with Siquijor as its third province.[15, 16, 17]
