In 2025, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain maximum sustained winds of 35 knots (65 km/h; 40 mph). The strongest system this year so far is Cyclone Vince which attained a minimum barometric pressure of 923 hPa (27.26 inHg), Cyclone Jude is the deadliest system this year so far, causing at least 21 deaths in south-east Africa. Cyclone Garance is the costliest system this year so far at $940 million in damage. The accumulated cyclone energy (ACE) index for the year (seven basins combined) so far, as calculated by Colorado State University (CSU), is 259.1 units overall.[1]
Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization (WMO). These centers are: National Hurricane Center (NHC), Central Pacific Hurricane Center (CPHC), Japan Meteorological Agency (JMA), Indian Meteorological Department (IMD), Météo-France (MFR), Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), Australian Bureau of Meteorology (BoM), Papua New Guinea's National Weather Service (PNGNWS), Fiji Meteorological Service (FMS), and New Zealand's MetService. Unofficial, but still notable, warning centers include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA; albeit official within the Philippines), the United States's Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

Dikeledi formed on 6 January, gradually intensifying over the next four days until making landfalling in Northern Madagascar as a Category 2 equivalent cyclone on 11 January. The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near Nacala at that strength on 13 January. In late January, two tropical cyclones formed; one of them was the moderate Tropical Storm Faida, which brought heavy rainfall to Madagascar on 5 February. After Faida dissipated, Tropical Cyclone Vince entered the basin from the Australian region on 4 February. Four days later, it became the most intense cyclone of the season and the first very intense tropical cyclone since Cyclone Freddy two years before. At 12 February, Vince had transitioned to being extratropical. At the same day, Taliah had entered the basin fluctuating between a moderate tropical storm and a strong tropical storm before becoming a post-tropical cyclone at 18 February. Six days later, Garance and Honde had formed, Garance receiving its name the day after. Garance intensified rapidly into an Intense Tropical Cyclone, making landfall at Réunion at 28 February as a Category 2. Honde brought heavy rainfall to Mozambique and then southern Madagascar as a Category 1. Jude formed as a disturbance south of the Chagos Islands on 6 March. It intensified at 8 March, receiving its name. Ivone entered the basin on 8 March and on the same day intensified to a Moderate Tropical Storm and received its name. Jude made landfall in Mozambique as a Category 1 at 10 March. Courtney from the Australian region entered the basin on 29 March, becoming an intense tropical cyclone. After nearly a month of inactivity, on 20 April Subtropical storm Kanto was named reaching a peak intensity of 75 km/h (10 minute sustained) winds with a central pressure of 993 hPa. This was the first subtropical storm named by Meteo France, which added the subtropical cyclone category starting with this cyclone season.

The first half of January had Tropical Lows 09U and 10U. The latter half had Sean, 13U, Taliah, and Vince. On 17 January, the BoM designated Tropical Low 11U, which absorbed 10U, and later named Sean on 19 January. A day later, the storm rapidly intensified to a Category 4 major cyclone on the Australian cyclone scale, possessing a distinct eye and intense winds. Sean dissipated a couple days later. The cyclone caused heavy rainfall and gale-force winds across portions of Western Australia. A record amount of rain fell in Karratha, with 274.4 mm recorded within 24 hours on 20 January. Tropical Low 13U briefly tracked along the coast of Queensland and flooding killed a 63 year old woman. On 31 January, the BoM designated Tropical Lows 14U and 15U, which were later named Taliah and Vince. After dealing with moderate wind shear, on 3 February, Taliah peaked as a Category 3 severe tropical cyclone on the Australian cyclone scale and Category 2 on the SSHWS scale. Taliah exited the basin on 12 February. Vince was named on 2 February and also intensified to a Category 3 on the Australian cyclone scale before exiting BoM area of responsibility on 4 February. February started with Tropical Lows 16U and 19U, though both disturbances exited the basin and entered the Fiji Meteorological Service area of responsibility. Meanwhile, the BoM designated Tropical Low 18U on 7 February, which was named Zelia on 11 February. Two days later, Zelia underwent rapid intensification due to warm sea surface temperatures and relatively low wind shear. At 00:00 UTC 13 February, Zelia intensified to a Category 4 severe tropical cyclone and later to Category 5 intensity. Afterward, the cyclone stalled and underwent an eyewall replacement cycle (EWRC), which ended its rapid intensification phase. Radar imagery showed an EWRC, which was later completed before landfall near De Grey, northeast of Port Hedland. On 18 February, the Bureau of Meteorology designated Tropical Low 21U in the eastern side of the Indian Ocean. BOM later named the system Tropical Cyclone Bianca. On 20 February, a tropical low was spotted by the Bureau of Meteorology in the Coral Sea. The disturbance, initially designated by the agency as 22U, was noted to likely develop into a tropical cyclone over the next several days. Two days later, BOM upgraded the system to a category 1, with the name Alfred being assigned to it. On 25 February, Bianca peaked as a Category 4 severe tropical cyclone on the Australian cyclone scale and Category 3 on the SSHWS scale. Afterward, increasing wind shear and cooler sea surface temperatures caused the storm to rapidly weaken, dissipating on 27 February. Over the next couple of days, Alfred continued to gradually move to the east, and was upgraded to a Category 2 tropical cyclone in the Australian scale at 16:00 AEST on 24 February. As Alfred turned south, it intensified to Category 3 status on 26 February at 22:00 AEST. The next day, the BOM further upgraded Alfred to a Category 4 cyclone, with a small eye appearing on visible satellite imagery. Later that night, an eyewall replacement cycle (ERC) occurred, prompting Alfred to fluctuate between Categories 3 and 4 on 1 March, before further weakening down to a Category 1 the following day. The cyclone then restrengthened slightly to Category 2 status by 3 March, before being downgraded to Category 1 intensity on 8 March. Alfred made landfall at Moreton Island on 01:00 AEST March 8 as a Category 1 tropical cyclone, and was downgraded to a tropical low five hours later. Tropical Low 23U formed on 4 March before exiting the basin on 8 March. The system later intensified into Tropical Storm Ivone in the South-West Indian Ocean. Tropical Cyclone 25U formed on 17 March before dissipating on 21 March. Tropical Low 27U formed on 22 March and strengthened into Tropical Cyclone Courtney three days later. Afterward, Courtney intensified to a Category 5 cyclone on the Australian cyclone scale before entering the South-West Indian Ocean on 29 March. Tropical Cyclone Dianne formed near North Australia on 28 March and made landfall near Derby on 29 March. On 8 April, Tropical Low 29U formed in the Arafura Sea. Three days later, JTWC designated Tropical Cyclone 29S. Later on 15 April, 29S was designated as Errol by BoM. Shortly after the designation, the cyclone explosively intensified to a powerful Category 5 equivalent cyclone with peak winds of 260km/h and 919 hPa according to the JTWC. Tropical Low 30U formed in the Arafura Sea on 13 April. On 18 April, JTWC designated 30U as 31P. It was expected to strengthen, but wind shear soon caused it to dissipate on 23 April.

Tropical Disturbance 03F was designated on 5 January and stayed out to sea moving southeastwards before dissipating 3 days later.
The first named storm of the season, Tropical Cyclone Pita formed on 9 January. The storm dropped heavy rains that resulted in flooding across Samoa and Fiji, isolated flooding occurred in the latter nation including the collapse of a bridge.
After a long pause in activity, two Tropical Depressions (05F and 07F) were monitored in early and mid-February. 06F however failed to reach Tropical Depression status. Tropical Depression 08F were monitored later that month. On 22 February Tropical Cyclone Rae developed passing just east of Fiji. On 23 February, the Fiji Meteorological Service named Tropical Cyclone Rae. Rae peaked on 25 February with winds of 110km/h and 975 hpa. A few days later on 24 February, Tropical Cyclone Seru formed. Seru peaked with 110km/h and 980 hpa on 25 February. Rae and Seru turned extratropical on 26 February and 1 March, respectively. Late season activity edit After a second, even more significant lull in activity, Tropical Cyclone Tam was named on 14 April by the Fiji Meteorological Service. It intensified into a deep subtropical cyclone by 16 April, bringing severe weather to northern New Zealand and causing 5 deaths in New South Wales in Australia.

[edit]Systems
[edit]January
[edit]
In January, the Intertropical Convergence Zone (ITCZ), which allows for the formation of tropical waves, is located in the Southern Hemisphere, remaining there until May.[2] This limits Northern Hemisphere cyclone formation to comparatively rare non-tropical sources.[3] In addition, the month's climate is also an important factor. In the Southern Hemisphere basins, January, at the height of the austral summer, is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month.[4] January was unusually active, with twelve systems forming and seven storms getting named.
The month started off in the South-West Indian Ocean with Cyclone Dikeledi, which intensified into a major cyclone before it made two landfalls at Antsiranana, Madagascar and Nampula Province, Mozambique, Cyclone Elvis and Cyclone Faida also formed but was downgraded into a depression by MFR in post-storm analysis. Meanwhile, short-lived Cyclone Pita formed on January 6, affecting some islands in the South Pacific basin. Weeks later, in the Australian basin, Cyclone Sean developed on January 17. Sean rapidly intensified into a Category 3-tropical cyclone, marking it the second major tropical cyclone of the year after Dikeledi. Cyclone Taliah and Cyclone Vince formed as well, with the latter rapidly intensifying into a Very Intense Tropical Cyclone in the South-West Indian Ocean, making it the strongest cyclone this month.

February
[edit]
February was extremely active. It was the most active month, and one of the third-most active months in any given year on record, with twelve systems forming and seven storms getting named. A total of seven tropical cyclones reached Category 3 strength or higher, the highest number since records began in 2003.
Historically, February is normally similar to January in terms of activity, with most formations being effectively restricted to the Southern Hemisphere (with the exception of the rare Western Pacific disturbance this year). The month also tends to see more strong tropical cyclones forming compared to January, despite seeing marginally fewer overall storms, due to the monsoon being at its height in the Southern Hemisphere.[4] In the Northern Hemisphere, February is the least active month, with no Eastern or Central Pacific tropical cyclones[8] and only one Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 2025, the month never saw a typhoon-strength storm, the first being Typhoon Higos in 2015.
The month started off active with five systems forming in January and then persisting into February: Faida, 13U, Vince, Taliah, and 05F. Cyclone Zelia formed on February 7 near the Kimberley region, and rapidly intensified into a Category 5 severe tropical cyclone six days later; it then made landfall near De Grey in Australia as a Category 4 tropical cyclone.[9] Two tropical cyclones formed in the Australian region on February 20 – Bianca and Alfred – while in the South-West Indian Ocean, two cyclones also formed near Madagascar: Garance and Honde. The former eventually became an intense tropical cyclone on February 27 before making landfall in the northern part of Réunion the next day as a slightly weaker tropical cyclone.

March
[edit]
During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February.[4] Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.
March was slightly-inactive, featuring five storms, all of them were named. Cyclone Alfred, Honde, and Garance formed in February and persisted into March. The strongest storm of the month is Cyclone Courtney. At the start of the month, Cyclone Jude caused 21 deaths in Southeastern Africa.

April
[edit].jpg)
The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March.[4][10] However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All Pacific typhoon seasons between 1998 and 2016 saw activity between January and April, although many of these seasons saw only weak tropical depressions.[11] By contrast, only two Atlantic hurricane seasons during those years saw tropical cyclone formation during that period.[12] With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.[10]
April 2025 was an example of this phenomenon, seeing four storms forming, three being named. The month started off in the Australian basin with the formation of Cyclone Errol, which would later become the first Category 5 equivalent cyclone of the year, and was the strongest cyclone of the month. Following that was the formation of Tropical Low 30U. In the South Pacific basin, Cyclone Tam formed and briefly impacted Vanuatu. On 20 April, Kanto formed, become the first subtropical cyclone in the South-west Indian Ocean since subtropical storm Issa in April 2022.

| Tam | April 14–16 | 85 (50) | 986 | Vanuatu, New Zealand | None | None | [13] |
| Kanto | April 20–21 | 75 (45) | 993 | None | None | None |
May
[edit]Around the middle of May, the Intertropical Convergence Zone (ITCZ), which allows for the formation of tropical waves and has previously remained in the Southern Hemisphere for the first five months of the year, moves to the Northern Hemisphere, allowing the northern cyclone seasons to start in earnest.[2] Without the presence of the ITCZ, Southern Hemisphere cyclones must form from non-wave sources, which are rarer.[3] For that reason, cyclone formation is relatively sparse, with May tending to be the month of the final storm in each of the three basins. Meanwhile, more intense storms are nearly unheard of, with the South-West Indian Ocean having seen only one intense tropical cyclone and no very intense tropical cyclones in the month, and the other two basins having similar levels of activity in May. In the Northern Hemisphere, May is the first month most basins see activity, due to the new presence of the ITCZ. The Pacific hurricane season begins on May 15, and although the Atlantic hurricane season officially begins on June 1, off-season storms are very common, with over half of the 21st century seasons seeing a storm form in May.[14] Although the North Indian Ocean has no official start or end date, due to the monsoon, mid-May is the beginning of a month-long period of high activity in the basin. Even in the Western Pacific, activity tends to increase throughout May.
So far, two storms have formed in May and none of them have been named.

Global effects
[edit]There are a total of seven tropical cyclone basins that tropical cyclones typically form in this table, data from all these basins are added.[15]
- ^ a b The wind speeds for this tropical cyclone/basin are based on the Saffir Simpson Scale which uses 1-minute sustained winds.
- ^ a b c d Only systems that formed either before or on December 31, 2025 are counted in the seasonal totals.
- ^ The wind speeds for this tropical cyclone/basin are based on the IMD Scale which uses 3-minute sustained winds.
- ^ a b c Only systems that formed either on or after January 1, 2025 are counted in the seasonal totals.
- ^ The wind speeds for this tropical cyclone are based on Météo-France, which uses wind gusts.
- ^ Although two systems formed in this basin, there are three named storms because after Tropical Low 08U moved into this basin, it was given a name, Dikeledi, by the MFR.
- ^ According to the BoM, Cyclones Vince, Taliah and Courtney entered the South-West Indian ocean basin from the Australian region
- ^ The sum of the number of systems in each basin will not equal the number shown as the total. This is because when systems move between basins, it creates a discrepancy in the actual number of systems.
