List of the wettest tropical cyclones by country

This is a list of wettest tropical cyclones by country, using all known available sources. Data is most complete for Australia, Cuba, Dominican Republic, Japan, Hong Kong, Mexico, Taiwan, Micronesia's Yap and Chuuk, and the United States, with fragmentary data available for other countries. The French region of Réunion holds several world records for tropical cyclone and worldwide rainfall, due to the rough topography and its location in the Indian Ocean.

Antigua and Barbuda

Australia

Christmas Island

Christmas Island is an Australian territory located in the Indian Ocean located at the summit of a submarine mountain, which rises steeply to a central plateau that is dominated by stands of rainforest. After rainfall and wind observations started on the island during 1972, only 13 tropical cyclones passed within  of the territory between 1972 and 2005.

Cocos Islands

The Cocos (Keeling) Islands are an Australian territory of 27 coral islands that are formed into two large coral atolls and cover an area of around  of the Indian Ocean to the northwest of Perth, Australia. Rainfall observations started on the islands during 1907, while temperature, wind and other records started in 1952. Between 1952 and 2005 27 tropical cyclones caused storm force wind gusts of over  on the islands, while only four caused hurricane-force gusts of over .

Bahamas

Bangladesh

Bangladesh has been the scene of the greatest tropical cyclone casualties in recent times. The country is quite flat and generally lies near sea level.

Belize
This country has terrain mainly across its southern sections, with elevations up to about . The highest reported rainfall in what was formerly British Honduras occurred during Hurricane Keith in 2000 when  of rain fell in a 24‑hour period at Phillip Goodson International Airport in Belize City. Equally heavy rains could have fallen during Hurricane Hattie of 1961 and Hurricane Fifi of 1974.

Cambodia

Canada

Tropical cyclones are usually in transition to extratropical cyclones by the time they reach Atlantic Canada, though occasionally they retain their tropical status. No tropical cyclone has ever hit Canada's Pacific coast.

China

China is a mountainous country, which leads to rapid dissipation of cyclones that move inland as well as significant amounts of rain from those dissipating cyclones. Typhoon Nina (1975) caused the collapse of two huge reservoirs and ten smaller dams when  fell in Henan during a 24‑hour period, which is the record for Mainland China. Typhoon Sam of the 1999 Pacific typhoon season became the wettest known tropical cyclone to impact Hong Kong since records began in 1884, breaking a 73‑year‑old record. Precipitation associated with tropical cyclones and their remains can bring snow to Tibet. An early October 2004 tropical depression brought daily precipitation of  of liquid equivalent precipitation to Che-Ku county in the form of heavy snow, which was a new October daily precipitation record for both rain and snow. This led to a loss of 340,000 kg of food, 230,000 kg of forage grass, and 263 livestock in the snowstorm.

Mainland

Hong Kong

Costa Rica

Cuba
Hurricane Flora of October 1963 drifted across Cuba for four days, leading to extreme rainfall across the mountainous island country. During the heaviest 24‑hour period of rainfall,  of rain fell at Santiago de Cuba. Total amounts of  over 4 days and  over 5 days produced staggering loss of life in Cuba, where over 2000 perished.

Réunion Island

The mountainous island of Réunion has experienced several of the highest rainfall totals on record from tropical cyclones and holds the rainfall world records for 12, 24, 48, 72 hours, four, five, six, seven, eight, nine and ten days as a result. The 12 and 24 hourly rainfall records were set at Foc-Foc by Cyclone Denise in 1966, while an Unnamed Tropical Cyclone between April 8–10, 1958 set the record for 48 hours at Aurere. Tropical Cyclone Gamede between February 24–28, 2007 came close to beating the records for 12, 24 and 48 hours before setting the records for three, four, five, six, seven, eight and nine days that were held by Tropical Cyclone Hyacinthe 1980. Hyacinthe 1980 currently holds the world records for ten and fifteen days with rainfall totals of  and  respectively recorded at Commerson Crater.

Saint Martin

Wallis and Futuna

Guatemala

The rainfall caused flash flooding and mudslides, primarily in Flores but also on West Timor and Sumba. In some locations, the depth of the floodwaters reached . The Oessao River in West Timor exceeded its banks, which flooded seven villages. In Kupang in West Timor, the system destroyed hundreds of homes and large fields of corn, bean, and rice crop. Heavy damage was reported near Ende, where flooding and mudslides destroyed 20 houses and destroyed the roads connecting to East Flores. The city airport was flooded with one meter (3 ft) of water, preventing aerial transportation and which left the city temporarily isolated.
