Satellite photos of the 24 tropical cyclones worldwide that reached at least Category3 on the Saffir–Simpson scale during 2012, from Funso in January to Freda in December. Among them, Sanba (first image in the third row) was the most intense, with a minimum central pressure of 900 hPa.
The strongest tropical cyclone was Typhoon Sanba, which strengthened to a minimum barometric pressure of 900mbar (hPa; 26.58inHg) before striking South Korea. The costliest tropical cyclone of the year was Hurricane Sandy, which caused $68.7 billion (2012 USD) in damages after striking the Caribbean and United States. The deadliest tropical cyclone of the year was Typhoon Bopha which caused widespread destruction on Mindanao, leaving thousands of people homeless and killing 1,901 people.

Global atmospheric and hydrological conditions
The Atlantic Ocean began an organization favorable to the sea surface temperatures, while the Eastern and Central Pacific Ocean began on unfavorable conditions due to dissipation of the 2010–12 La Niña event in April 2012. During the month of May to November along the Pacific hurricane season a favorable organization began due to the sea surface temperatures and the formation of El Niño–Southern Oscillation.

Summary
Nineteen tropical cyclones formed in the Atlantic hurricane season, the third-most active in history with previous 1887, 1995, 2010 and 2011 seasons. On East Pacific and Central Pacific, a total of 17 named storms formed during the season.

Perspective
A total of 132 systems formed globally in the year with 52 of them causing significant damage, deaths, and/or setting records for their basin.
January was the most active month of the year with 21 tropical cyclones forming, However, only six were named by specific tropical cyclone naming agencies. Intense Tropical Cyclone Funso produced flooding rains as it looped in the Mozambique Channel, killing at least 21 people, soon after Subtropical Depression Dando killed 10 people across southern Africa.
A total of nine tropical systems of all intensities were monitored during February 2012, of which five developed further and were named by the various warning centres. Intense Tropical Cyclone Giovanna was a powerful tropical cyclone that affected Madagascar. Giovanna is still blamed for 33 deaths along the Madagascar coast, and it is the first intense tropical cyclone to impact Madagascar, since Cyclone Bingiza in February 2011.
A total of twelve tropical systems of all intensities were monitored during March 2012, of which four developed further and were named by the various warning centres. Cyclone Lua affected a sparsely populated region of Western Australia.
A total of 4 tropical cyclones formed during this month, making this month the least active of 2012. None of these tropical cyclones were tropical storm strength or higher, thus making Tropical Cyclone Daphne, which was formed in March as the strongest tropical cyclone of this month.
Leeward Islands, Puerto Rico, Hispaniola, Cuba, The Bahamas, Southeastern United States (Florida, Louisiana, Arkansas, Mississippi, and Alabama), Midwestern United States (Missouri, Illinois, and Indiana), Kentucky
1 Only systems that formed either on or after January 1, 2012 are counted in the seasonal totals. 2 Only systems that formed either before or on December 31, 2012 are counted in the seasonal totals. 3 The wind speeds for this tropical cyclone/basin are based on the IMD Scale which uses 3-minute sustained winds.
4 The wind speeds for this tropical cyclone/basin are based on the Saffir Simpson Scale which uses 1-minute sustained winds. 5The wind speeds for this tropical cyclone are based on Météo-France which uses gust winds.
