During 2012, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 128 tropical cyclones had formed this year to date. 85 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC).

The most active basin in the year was the Western Pacific, which documented 25 named systems, while the North Atlantic saw its fourth-most-active season on record, tied with 1887, 1995, 2010, and 2011. Conversely, the Eastern Pacific hurricane season experienced an average number of cyclones reaching tropical storm intensity, numbering 17 respectively. The least-active basin of the year was the North Indian Ocean, which had a late start with its first system forming in October. Activity across the southern hemisphere's three basins—South-West Indian, Australian, and South Pacific—was spread evenly, with each region recording seven named storms apiece. So far, twenty-four Category 3 tropical cyclones formed, including three Category 5 tropical cyclones in the year. The accumulated cyclone energy (ACE) index for the 2012 (seven basins combined), as calculated by Colorado State University was 740.5 units.

The strongest tropical cyclone was Typhoon Sanba, which strengthened to a minimum barometric pressure of 900 mbar (hPa; 26.58 inHg) 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.

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.

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.

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 being named. 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.
