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 II^[29]

No dry season. The rain is heaviest from December to February, and no month is truly dry.

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.

Life & Economy

About 35 of every 100 people lived below the poverty line in 2021.

Poverty, 2021Poverty incidenceHow many of every 100 people live in families whose income is below the poverty line: what a person needs in a year for food and other basic needs, as the PSA sets it for each province. It is an estimate, from a survey or, for a town, a statistical model, so the PSA gives a range it is likely to fall in.More in the glossary: 35.2% of people^[17]Below the poverty line, by the PSA's estimate for every town.
Income classIncome classThe Department of Finance sorts provinces, cities and municipalities into classes by their average yearly income over recent years: 1st class has the most. It measures the local government's income, not how well off its people are.More in the glossary: 1st class^[4]

About 35 of every 100 people in Guiuan lived below the poverty line in 2021 (35.2%)^[17]

The PSA's model for every town puts it between 31.4% and 39.1%, with 90% confidence.

Eastern Visayas
Eastern Visayas: San Lazaro, the first name
On 17 March 1521 Magellan's crew landed on Homonhon and called the islands the archipelago of San Lazaro, the country's first European name. Felipinas came 22 years later.

Spain called the Visayans the painted ones
Before they were called Visayans, Spain called them Pintados, for tattoos earned by bravery. Where the word Bisaya comes from, nobody knows for sure; a Bornean legend has its own answer.
Why It's Called That

All Stories

How it got its name

Local traditionThe provincial page says early settlers first called the place Guibang after a sharp break in the mountain range that shields the town from the Pacific, and the name was later changed to Guiuan.^[9]

Its story

The provincial page notes that Magellan, in 1521, landed on Homonhon, an island now within Guiuan.^[9]

In 1903 Act No. 960 of the Philippine Commission folded the former municipalities of Mercedes and Salcedo into Guiuan, with the seat of government at Guiuan.^[10]

The town page says Japanese soldiers first arrived on 28 June 1943 and that relations with townspeople stayed mostly cordial.^[9]

In December 1944 landing craft and cargo ships unloaded at Guiuan Bay the equipment that turned the town into a major naval base.^[9]

In 1952 five sitios of Barrio Tubabao were separated to form the barrio of Trinidad.^[9]

The town page records that Typhoon Haiyan (Yolanda) struck Guiuan in November 2013, heavily damaging nearly every building.^[9]
