The 2011 Thai floods occurred at the end of March 2011, normally the latter part of the dry season (Thai: ฤดูแล้ง, romanized: reutdu lang or หน้าแล้ง nah lang) in tropical Thailand.
[6] Close to 160,000 ha (400,000 acres) of land were submerged.
[2] Around 5,000 households were evacuated,[7] in addition to hundreds of tourists.
[8] The floods hit during a typically dry season, and were triggered when a record cold wave moved south from East Asia and produced persistent flooding in combination with near-normal sea surface temperatures, still warm enough to support strong convectional precipitation.
[9] However, Thailand's Deputy Chief Negotiator for the UNFCCC stated that the floods were likely caused by climate change, as over 2,200 mm (87 in) of rain had fallen in parts of Southern Thailand for the four months leading up to the beginning of April while the year of 2010 saw a total of 270 cm (110 in).
