Tangalle sits in Sri Lanka’s dry zone in the north or east, where the northeast monsoon from October through January is the dominant source of rainfall, in contrast to the southwest monsoon that soaks the island’s wet zone.
On the southeastern coast, the town’s drier climate means an intense rain event can still overwhelm drainage built for a generally lower rainfall norm. Because this region’s rainfall is concentrated into a shorter, later season than the rest of the island, an intense northeast monsoon storm can produce flooding relatively quickly on terrain that spends much of the year dry, and radar helps track these seasonal rain bands as they develop.
