The deadliest storm of the year was Cyclone Nargis, which caused devastating and castatrophic destruction in Myanmar with 138,373 fatalities.

The costliest storm of the year was Hurricane Ike, which wreaked havoc thorough Cuba and Texas, with $38 billion (2008 USD) in damage.

The accumulated cyclone energy (ACE) index for the 2008 (seven basins combined), as calculated by Colorado State University was 613.9 units.

Tropical cyclones are primarily monitored by a group of ten warning centres, which have been designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization.

Other notable warning centres include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the United States Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

It was the only year on record in which a major hurricane existed in every month from July through November in the North Atlantic.

Bertha became the longest-lived July tropical cyclone on record for the basin, the first of several long-lived systems during 2008.

Overall, the season's activity was reflected with a total cumulative accumulated cyclone energy (ACE) rating of 146, which was well above the normal average, and was the highest value since 2005.

These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin.

Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed.

It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 39 miles per hour (63 km/h).

After two more Tropical depressions, the first named storm, Typhoon Neoguri formed in April to the east of Mindanao.

The IMD monitored a total of ten depressions across the North Indian Ocean, significantly below the average of fifteen.

[5] The JTWC unofficially tracked seven systems, with six having one-minute sustained winds greater than 65 kilometres per hour (40 mph), slightly above their 32-year average of five.

Overall, the impact of this season was relatively minor, but damaging for Madagascar, due to the heavy rains from Eric, Fanele, Izilda and Jade.

Melanie was the first storm of the season to require cyclone watches, and warnings were issued for the Pilbara coast, but it had weakened into a low-pressure area before it made landfall.

[12][13] The season officially ran from November 1, 2007, until April 30, 2008, although the first cyclone, Tropical Depression 01F, developed on October 17.

[14] During the season, a total of fifteen significant tropical disturbances were monitored and numbered by the Fiji Meteorological Service (FMS), within the South Pacific basin between 160°E and 120°W.

After it made landfall Innis became the first Tropical Depression to move into TCWC Brisbane's Area of responsibility since Cyclone Larry.

Cyclone Jasper then moved into the region early on March 24 at peak intensity, having developed inside TCWC Brisbane's area of responsibility two days earlier.

A total of 124 systems formed globally in the year with 83 of them causing significant damage, deaths, and/or setting records for their basin.

March is tied with April and June as the least active month, with just six tropical cyclones; however, four of them are named.

Typhoon Neoguri was the earliest tropical cyclone on record to strike the mainland China, which left 26 deaths and over $65 million worth of damages to the said country.

Included here is Typhoon Rammasun, which brought gusty rainfalls across eastern Philippines and paralleled on Japan before weakening.

Fengshen made a direct hit on the Philippines and China, causing severe damage and resulted in at least 1,371 deaths and leaving at least 87 people missing.

On the North Indian Ocean basin, ARB 01 and BOB 02 formed; bringing torrential rainfall and damages on Oman, India and Bangladesh.

It affected the East Coast of the United States and Bermuda, leaving 3 fatalities and minimal damages.

Back in the West Pacific, the activity started with Gener which impacted Guangdong Province in China.

Adding on, Fung-wong severely impacted Taiwan as a Category 2 typhoon, just 10 days after Kalmaegi lashed the country.

A tropical depression brought torrential rainfalls across Southwestern Mexico, leaving 2 deaths and $2.2 million worth of damages.
