Rainfall pattern is influenced by monsoon winds from the Indian Ocean and Bay of Bengal. The "wet zone" and some of the windward slopes of the central highlands receive up to 2,500 millimetres (98.4 in) of rain each month, but the leeward slopes in the east and northeast receive little rain. Most of the east, southeast, and northern parts of the country comprise the "dry zone", which receives between 1,200 mm (47 in) and 1,900 mm (75 in) of rain annually.[143] The arid northwest and southeast coasts receive the least amount of rain at 800 mm (31 in) to 1,200 mm (47 in) per year. Periodic squalls occur and sometimes tropical cyclones bring overcast skies and rains to the southwest, northeast, and eastern parts of the island. Humidity is typically higher in the southwest and mountainous areas and depends on the seasonal patterns of rainfall.

The country has 103 rivers. The longest of these is the Mahaweli River, extending 335 kilometres (208 mi).[145] These waterways give rise to 51 natural waterfalls of 10 meters or more. The highest is Bambarakanda Falls, with a height of 263 metres (863 ft).[146] Sri Lanka's coastline is 1,585 km long.[147] It claims an Exclusive Economic Zone (EEZ) extending 200 nautical miles, which is approximately 6.7 times the country's land area. The coastline and adjacent waters support highly productive marine ecosystems such as fringing coral reefs and shallow beds of coastal and estuarine seagrasses.[148] Sri Lanka has 45 estuaries and 40 lagoons.[147] The country's mangrove ecosystem, which spans over 7,000 hectares, played a vital role in buffering the force of the waves in the 2004 Indian Ocean tsunami.[149] The island is rich in minerals such as ilmenite, feldspar, graphite, silica, kaolin, mica and thorium.[150][151] Existence of petroleum in the Gulf of Mannar has also been confirmed and extraction attempts are underway.[152]
