Pekanbaru sits on Sumatra, close enough to the equator that rainfall is distributed fairly evenly throughout the year, though a somewhat wetter period typically runs from October through January.
On the Siak River in Riau province, the city’s peatland surroundings are prone to both flooding and dry-season fire risk depending on the timing of rainfall. Because rain is a near-constant feature of the climate here, flooding is often driven less by a single dramatic storm season and more by cumulative rainfall combined with deforestation and peatland drainage changes, and radar remains useful for identifying the more intense rain bands within this generally wet pattern.
