Tropical Storm Sinlaku formed west of Pohnpei on April 8, later intensified into a typhoon on April 10 and was recognised as a super typhoon on April 12, it later reached a peak of 115 knots (215 km/h) and 905 mb (26.72 inHg). Tropical Storm Hagupit formed near Chuuk on May 5, it entered the PAR on May 9, gaining the name Caloy. Tropical Storm Jangmi formed on May 26 and entered the PAR on May 28, gaining the name Domeng, it slowly intensified into a category 1 typhoon on May 30 before making landfall in Wakayama on June 3. A tropical depression formed on June 3, it entered the PAR on June 4, gaining the name Ester, a few hours later, JTWC classified it as a subtropical depression before making landfall in Taiwan. On June 18, Tropical Storm Mekkhala formed south of the Mariana Islands, it rapidly intensified into a Category 4 typhoon on June 22. Tropical Storm Higos formed the same day.

North Indian Ocean

On 7 January, BOB 01 formed in the Bay of Bengal.^[4] It remains the only tropical cyclone of the season so far in the North Indian Ocean basin.

South-West Indian Ocean

January - June

The first cyclone of the year for this basin was Grant, which entered the basin on December 27 and rapidly intensified into an Intense Tropical Cyclone, and persisted into the new year.^[5] In mid-January, Dudzai formed and rapidly intensified into an Intense Tropical Cyclone.^[6] Ewetse formed and made landfall in Madagascar the following day. Zone of Disturbed Weather 08 formed on February 27. Fytia formed in the Mozambique Channel and intensified into a tropical cyclone on January 30. Gezani soon formed two days after Fytia dissipated. Horacio formed less than one day after Gezani turned post-tropical. Horacio strengthened to category 5 strength on the Saffir-Simpson Hurricane Wind Scale on 24 February, making it the first tropical cyclone to have reached that intensity this year. Tropical Depression 12 formed on March 12 and Cyclone Indusa formed on April 1. An extratropical cyclone formed on April 26, it later developed subtropical characteristics, and was named Juluka the following day.

Australian Region

January - June

07U formed in the Arafura Sea on December 14, and it didn’t dissipate until January 1. Iggy formed near Indonesia on December 29. Jenna followed suit on 3 January, and Koji formed off the northeast Queensland coast on 10 January. After developing in the Coral Sea and reaching Category 2 intensity, Tropical Cyclone Koji weakened to a tropical low before making landfall between Ayr and Bowen, Queensland, on the morning of 11 January, 2026, where it delivered life-threatening rainfall and flash flooding. Tropical Cyclone Luana formed from Koji’s remnants on January 18, and Mitchell formed on 6 February. Tropical Low 23U formed on February 11, 26U formed on February 24. Tropical Lows 30U, 28U, 31U and 29U formed on March 1 and 2, and Cyclone Narelle formed March 17. A week after Narelle became extratropical, Cyclone Maila formed. It was the first tropical cyclone in TCWC Port Moresby’s area of responsibility since Cyclone Guba in 2007.

South Pacific Ocean

January - June

A tropical disturbance spotted near American Samoa on December 29, and was designated 04F by FMS. Tropical Low 14U, Tropical Storm 16P and Tropical Low 17U crossed into the South Pacific basin and was designated 05F, 06F and 07F. Tropical Disturbances 08F and Urmil also formed. Urmil became the latest tropical cyclone to be named, surpassing Bart in 2017. Tropical Depression 10F and Cyclone Vaianu formed.

South Atlantic Ocean

On February 28, a subtropical depression formed off the coast of the State of Rio De Janeiro in the South Atlantic. A second subtropical depression to its north formed two days later, the depression intensified into a subtropical storm then got named Caiobá. This is the first recorded occasion in which multiple (sub)tropical cyclones co-existed in the South Atlantic.

Mediterranean Sea

A European windstorm named Samuel, known as Jolina in Germany, transitioned into a tropical-like cyclone over the south-central Mediterranean sea. It moved inland over Libya on 18 March.

January

January was an unusually active month, with fifteen tropical cyclones forming and seven of them being named, the highest number since 2021. Out of the seven, Dudzai is the strongest cyclone of the month. Two cyclones, Grant and Iggy, persisted from the previous year into the current year. In the Northern Indian Ocean, BOB 01 formed on January 7, making it one of the earliest depressions ever recorded in the basin. Also, the Western Pacific season began with the formation of Tropical Storm Nokaen (locally known as Ada in the Philippines), which was named on January 15, although it originally formed two days earlier as a tropical depression. Nokaen became the first tropical cyclone to form in the Western Pacific in January since Tropical Storm Pabuk in 2019. In the Southwestern Indian Ocean, Cyclones Dudzai, Ewetse and Fytia formed, with the latter two affecting Madagascar and the former, Dudzai, intensifying into the month’s strongest system. To add on, Fytia rapidly intensified into a Category 3-equivalent cyclone in the Mozambique Channel before making landfall in Madagascar, causing 12 deaths in the country.^[7]

February

February was below average in activity, however, it spawned several powerful tropical cyclones, including Horacio, which rapidly intensified into a Category 5 tropical cyclone and became the strongest tropical cyclone of the month; additionally, it is also the first tropical cyclone to do so this year. Eight tropical cyclones have formed this month, with five of them being named. February started with Cyclone Fytia persisting from the previous month into this month. The series of early-season systems of the Western Pacific continued with Basyang, which formed near Yap on February 2. It was later named Penha two days later, becoming the first tropical cyclone to form in the month of February since Tropical Storm Dujuan in 2021. Penha went on to make landfall in Bayabas, Surigao del Sur on February 5 and was followed by multiple landfalls in Visayas the next day. Afterwards, land interaction and hostile conditions caused the storm to degenerate into a tropical depression. In the Australian region, Cyclone Mitchell formed from a meandering tropical low. It then rapidly intensified into a Category 3-equivalent cyclone on the Australian scale. On February 10, Gezani caused over 63 deaths in Madagascar. On February 24, Horacio rapidly intensified into a Category 5 tropical cyclone. In the South Pacific basin, Urmil developed on February 27, becoming the latest-forming first-named tropical cyclone of the season within that basin, breaking the record set by Cyclone Bart during the 2016–17 season. On February 28, a Subtropical Depression formed off the coast of the State of Rio De Janeiro in the South Atlantic.

March

March was slightly inactive, featuring eleven storms, four of which were named. Out of the four, Narelle was the strongest storm of the month. It started with the dissipation of Cyclone Urmil, a subtropical depression, and Tropical Low 26U persisting from the previous month into this month. Subtropical Storm Caiobá soon followed suit in the South Atlantic, coexisting with the previously mentioned subtropical depression, the first time in recorded history where two simultaneous subtropical cyclones existed in the South Atlantic. Meanwhile in the Western Pacific Basin, Tropical Storm Nuri and a Tropical Depression formed northeast of Yap on 10 March, continuing the early-season activity. On 15 March, Cyclone Narelle formed off the Australian coast, and then rapidly intensified upon its formation and naming, eventually becoming the strongest cyclone in the basin since Cyclone Ilsa in 2023. Narelle would later cross Australia and reach secondary peak as a Category 4. On 17 March, a European windstorm named Samuel, or Jolina in Germany, transitioned into a Mediterranean tropical-like cyclone before making landfall in Libya early the next day.

April

April was above-average, the most active since 2022. The month saw six cyclones forming, five of them being named, with Sinlaku being the strongest and the strongest of the year so far. Three tropical cyclones formed within the first three days of the month: those being Indusa in the South-West Indian basin, Maila in the Australian region, and Vaianu in the South Pacific. Indusa formed on the first day and was upgraded to a tropical cyclone on 3 April; two days later, it transitioned into a post-tropical cyclone. Maila formed a day after Indusa and became a very rare system, having been named by Port Moresby on 4 April, the first to do so since Cyclone Guba just nearly nineteen years ago. Vaianu formed and rapidly intensified into a severe tropical cyclone, the first in the basin since Cyclone Mal in 2023, ending the longest streak of seasons without a severe tropical cyclone of such intensity in the satellite era. On April 8th, a tropical depression formed off Pohnpei which became Typhoon Sinlaku, therefore continuing 2026's streak of early-season cyclone activity in the Western Pacific. From April 13-16th, Tropical Low 38U existed in the far eastern Indian Ocean in the Australian region without developing into a full-fledged tropical cyclone. On April 26th, a subtropical depression formed south of Madagascar, becoming Subtropical Storm Juluka the following day.

May

May was significantly below-average, the least active since 2016. Three tropical cyclones formed, and two of them were named. All of which formed in the Western Pacific basin. Tropical Storm Hagupit formed in the early part of the month, and proceeded to exist as a tropical cyclone for ten days, albeit its intensity remained weak throughout its lifetime. Hagupit caused minimal damage in the Caroline Islands. A short-lived tropical depression briefly accompanied Hagupit a few days after its formation. Severe Tropical Storm Jangmi formed in late May, and went on to become a broad system with a very large circulation, persisting into June. Jangmi affected the Japanese Islands as June began.

June

So far, June has been a rather active month, with eight cyclones forming within the month. Six were officially named, excluding a system that is deemed unofficially named outside the Philippines, that being Tropical Depression Ester. The month of June began with Jangmi, a severe tropical storm persisting from the previous month into the current month. On June 2, Tropical Storm Amanda formed in the Eastern Pacific, becoming the first tropical cyclone of the 2026 Pacific hurricane season. The following day, a tropical depression developed in the South China Sea in the Western Pacific basin, being named Ester by the Philippines. Meanwhile in the Eastern Pacific, Tropical Storm Boris affected southern Mexico while Tropical Storm Cristina dumped heavy rain across Central America. On June 9, a tropical depression formed in a similar area to where Ester formed, affecting similar areas and taking the same general trajectory as the aforementioned system. On June 17, Tropical Storm Arthur formed in the Gulf of Mexico after emerging off the coast of Texas, becoming the first named storm of the 2026 Atlantic hurricane season. The following day, Tropical Storm Mekkhala formed south of the Mariana Islands, due to very favourable conditions, Mekkhala rapidly intensified into a typhoon on June 21. Early the next day, Tropical Storm Higos formed to the west of the Mariana Islands.
