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.

Everything listed for Negros Occidental in Now

Created
A province of its own since 1 January 1890, when a royal decree divided the island of Negros; its civil government was set up under Act No. 119, enacted 20 April 1901, with Bacolod as its capital[9, 10]

How it got its name

The Spaniards named the island Negros after the dark-skinned people, the Ati, whom they found living there when they first came in 1565.[9, 11]

Sources differIts people knew it as Buglas, and the two Negros provinces explain the word differently: Negros Occidental's account reads it as an old word thought to mean cut off, the island being believed to have once been part of a larger land, while Negros Oriental's names a tall grass like sugar cane that grew there in plenty.[9, 11, 12]

Its story

After appointing encomenderos on the island, Miguel Lopez de Legaspi placed Negros under the jurisdiction of the governor of Oton, in Panay. Two of its earliest native settlements, Binalbagan and Ilog, became towns in 1573 and 1584.[11]

The island became a military district in 1734 with Ilog as its capital; the seat moved to Himamaylan and, in 1849, to Bacolod.[11]

Sugar remade it in the second half of the 19th century: the province produced 4,000 piculs in 1856 and 2,000,000 in 1893, and settlers from Iloilo, Antique, Capiz and Cebu founded new towns.[11]

Under a royal decree, the island was divided on 1 January 1890 into two provinces, Negros Occidental, with Bacolod as its capital, and Negros Oriental.[9, 11]

On 5 November 1898 revolutionaries led by Aniceto Lacson and Juan Araneta made the Spanish garrison surrender, and the short-lived Republic of Negros followed.[9, 11]

Local traditionAs the province tells it, they won by bluffing: their rifles were carved from palm fronds and their cannons made of bamboo mats painted black.[9]

In 1985 Batas Pambansa Blg. 885 carved a Province of Negros del Norte out of its northern cities and towns. In 1986 the Supreme Court struck the law down: the plebiscite of 3 January 1986 had left out the voters of the rest of the province, and the new province did not meet the criteria the law set for one.[13, 14]

It was joined with Negros Oriental 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]
