Ahead of the season officially starting on November 1, the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BoM), National Institute of Water and Atmospheric Research (NIWA) and the University of Newcastle's Australian Centre for Water, Climate and Land (ACWCL), each issued a tropical cyclone outlook that discussed the upcoming season.

On December 10, the FMS reported that Tropical Disturbance 01F had developed, within an area of low vertical windshear near Fiji's southern Lau Islands.

[20] However, on January 8, the JTWC gave the system's chance for development, although in favorable environment, as low since it was in close proximity with Hale.

[25] The FMS issued their last advisory on Hale by the next day as it moved east-southeast towards the TCWC Wellington's area of responsibility,[26] where they reclassified it as an extratropical low six hours later.

[30] Hale caused widespread flooding and slips in northern and eastern parts of the country on January 10 and 11, particularly in the Coromandel and Gisborne areas.

[31] Washed away forestry slash clogged many rivers in the Gisborne region, exacerbating the flooding and accumulating around bridges downstream.

[32] Several metres of foreshore was eroded away by the storm surge in Whitianga, threatening waterfront buildings such as the Mercury Bay Boating Club.

[33] A child was killed on Waikanae Beach on January 25, two weeks after Hale impacted the country, after falling while playing on forestry slash debris left behind by the cyclone.

[36] However, the low formed in the Australian region late on the same day,[37] and by January 14, it organized into a tropical disturbance, with the FMS designating it as 05F.

[43] The FMS subsequently followed suit, upgrading the system into a Category 1 tropical cyclone on the Australian scale and naming it Irene.

[45] Under a favorable environment of warm sea surface temperatures, low wind shear and strong poleward outflow,[46] Irene intensified into a Category 2 tropical cyclone late on the same day.

[47] However, as it moved over Tanna Island in Vanuatu, its weakly-defined and elongated low-level circulation center quickly became exposed due to the wind shear,[48] prompting the JTWC to issue its final warning on Irene and reclassify the system as a subtropical cyclone by January 19.

[56] With the system becoming fully exposed due to increasing wind shear and large amounts of dry air, the JTWC would issue their final advisory on 06F the next day.

[59] The remnants of the system impacted New Zealand on January 27, causing severe flooding which killed 4 people and resulted in US$1.2 billion in damages.

[61][62] Gabrielle began to experience an increase in northwesterly vertical wind shear, the JTWC downgraded it to a Category 1-equivalent cyclone.

[72] Heavy rain and strong winds led to widespread power outages and flooding across the upper North Island, with a national state of emergency being declared on February 14.

[74] New Zealand declared a national state of emergency for the third time in its history on February 14 as Cyclone Gabrielle caused widespread flooding, landslides and huge ocean swells.

[75] On February 22, the FMS reported that a low-pressure system was located just south of Samoa, and gave it a low chance of formation into a tropical cyclone in the next 5 days.

[76] Under a moderate sheared environment and warm sea surface temperatures, the system organized into a tropical disturbance late on the next day, with the FMS designating it as 08F.

[100]Late on March 8, the FMS reported that Tropical Disturbance 10F formed near Niue, and gave the system a low chance for development.

[102] Under an environment of warm sea surface temperatures, low to moderate wind shear, and excellent upper-level outflow, the system rapidly developed, prompting the JTWC to issue a TCFA late on the same day.

[104] However, the system's low-level circulation became elongated and weakly-defined, with its convection being sheared to the east, prompting the JTWC to cancel its TCFA late on March 11.

[106] On March 11, the FMS reported that Tropical Disturbance 11F had developed, within an environment of warm sea surface temperatures, low wind shear and moderate upper divergence, to the west of Tonga.

[citation needed] Under high vertical wind shear, the JTWC canceled the TCFA again and redowngraded its chance of the system becoming a cyclone to low.

[110] Late on March 11, the FMS reported that Tropical Disturbance 12F had developed, within an environment of warm sea surface temperatures, low wind shear and good upper divergence, to the northeast of Vanuatu.

[citation needed] On April 15, the FMS reported that Tropical Disturbance 13F had developed about 630 km (390 mi) to the northwest of Port Vila in Vanuatu.
