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^[15]

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

Covers about 70 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.

As OpenStreetMap maps them on September 30, 2026. Each place is listed by where it stands on the map, inside the barangay's border on UN OCHA's map. Near that border, or when its own name says which barangay it belongs to, the address it gives decides. The border is a guide, so a place near the edge may stand in the barangay next door. A place on the shore whose point lies just past the border is given to the nearest barangay. Map data © OpenStreetMap contributors, under the Open Database License.
