Overall, Sir Lanka has a varied terrain but it mainly consists of flat lands but south-central portion of the country's interior features mountain and step sided river canyons. The flatter regions are the areas where most of Sri Lanka's agriculture takes place, aside from coconut farms along the coast.
Sri Lanka's climate is tropical and the southwestern part of the island is the wettest. Most of the rain in the southwest falls from April to June and October to November. The northeastern part of Sri Lanka is drier and most of its rain falls from December to February. Sri Lanka's average yearly temperature is around 86°F to 91°F (28°C to 31°C).
An important geographic note about Sri Lanka is its position in the Indian Ocean, which made it vulnerable to one of the world's largest natural disasters. On December, 26, 2004, it was struck by large tsunami that hit 12 Asian countries. Around 38,000 people in Sri Lanka were killed during this event and much of Sri Lanka's coast was destroyed.
