. Because of the low number of storms in the 2009 season, many of which were weak, short-lived, and/or very disorganized, the overall ACE value was ranked as below-average, totaling under 66. Being the most intense hurricane, Hurricane Bill was responsible for the ACE value for August being 30% above average. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding or tropical storm strength. Subtropical cyclones are excluded from the total.

. The season officially started on Friday, May 15, 2009, in the East Pacific Ocean, and on Monday, June 1, 2009, in the Central Pacific; they both ended on Monday, November 30, 2009. These dates conventionally delimit the period of each year when most tropical cyclones form in the Eastern and Central Pacific basins. However, the formation of tropical cyclones is possible at any time of the year. There were no off-season storms, as the season began relatively late, and ended very early. The

(ACE) index for the 2009 Pacific hurricane season was 117.09 units in the Eastern Pacific and 9.905 units in the Central Pacific. The total ACE in the basin combined is 126.995 units. 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 . The season, however, was characterized as "near-normal", featuring 17 named storms 8 hurricanes and 5 major hurricanes. The central Pacific experienced above-average activity with three additional storms forming west of 140°W and three more crossing over from the eastern Pacific. The overall number of storms led to a relative lull in activity experienced over the previous decade. During the course of the year, large-scale factors such as an El Niño and two Madden–Julian oscillations greatly contributed to the changed pattern. The season's activity, east of 140°W, was reflected with a near-average cumulative

The season's first named storm, Kujira, developed on May 3 while the season's last named storm, Nida, dissipated on December 3. Nida was the most intense of the whole year worldwide.


North Indian Ocean

Systems

There have been 128 tropical disturbances that have formed in 2009, marking an above-average year in tropical cyclone formation throughout the world. One was believed to have formed in the South Atlantic Ocean in late January, and was unofficially added in the 2009 advisories. 82 further intensified to tropical storms, and each received named from each tropical cyclone agency.


January

During January 2009, a total of 14 tropical cyclones formed, while 8 were named. The Cyclone Fanele was the most intense of the month, reaching category 4 on the SSHWS scale, with a barometric pressure of 930 mbar. The other storms were relatively weak, with a force equivalent to a tropical storm. A rare subtropical system was reported in the southern Atlantic, affecting the southern coasts of Brazil and Uruguay. No major damage or death was reported.


February

February was moderately active


March

March was moderately active


April

April was relatively inactive,


May

May was relatively inactive,


June

June was relatively inactive with six tropical cyclones and three tropical storm-equivalent cyclones forming. Hurricane Andres gave the 2009 Pacific hurricane season a late start when it formed on June 21 (the latest start on record until the record was beaten exactly a decade later when Alvin formed on June 25, 2019).


July

July was slightly inactive in terms of intensity per tropical cyclones, and slightly active in terms of number of tropical cyclones that formed, with nine. Seven were tropical storm equivalent, and only two were hurricane or typhoon equivalent tropical cyclones. No majors. Although Hurricane Carlos was the most intense of the month, none of the tropical cyclones caused any form of severe destruction. Over 50 people were killed, however, a deadly exception.


August

August was the most active month the year that 21 tropical cyclones formed throughout the world. 16 attained sustained wind speeds of or greater. Tropical Storm Ana became the first named storm of the very inactive 2009 Atlantic hurricane season, when it formed on August 11, one of that latest first named storms on record since Alex of 2004. Typhoon Morakot (Kiko) was the deadliest tropical cyclone of the year, killing 789 total. Hurricane Jimena became the most intense of the month in the latter portion of August.


September

September was the second-most active of the year.


October

October was inactive in terms of tropical cyclones, but it was slightly active in terms of intensity in hPa/mbar., especially towards the end of the month. 10 tropical cyclones formed in October 2009. 9 of those attained storm intensities and were named. Hurricane Rick was the third-most intense Pacific hurricane on record, as well as the second-most intense of 2009 worldwide. The 2009 Pacific hurricane season ended slightly earlier than usual when Hurricane Neki dissipated on October 27


November

November was relatively inactive with only 10 tropical cyclones forming and 5 attaining tropical storm intensities. The inactive 2009 Atlantic hurricane season ended when Hurricane Ida dissipated on November 10 (it transitioned to a Nor'easter just after, so it ended when "Nor'Ida" dissipated) Despite two tropical disturbances forming in August and September, the 2009–10 South-West Indian Ocean cyclone season actually didn't see a named tropical storm form until November 13. The start to the season was pretty intense when Cyclone Anja peaked at 950 hPa. Typhoon Nida was the most intense of the year, peaking at a pressure of 905 hPa, just ahead of Hurricane Rick of the previous month.


December

December was relatively and slightly inactive
