[3][4] These outlooks took into account a variety of factors such as a developing weak to moderate La Niña event and what had happened in previous seasons such as 1971–72, 1974–75, 1976–77, 1983–84, 1985–86, 1985–86, 2000–01, 2005–06, 2007–08 and 2008–09.

[3] Both outlooks also predicted that the majority of systems would occur to the west of the International Dateline, which as a result meant that New Caledonia and Vanuatu had a high chance of being impacted by a tropical cyclone.

[6][7] RSMC Nadi then declared the low-pressure area: Tropical Depression 01F later that day, while it was located about 400 km (250 mi) to the north of Suva, Fiji.

[8] During the next day, the disturbance moved towards the southwest and onto the main Fijian Islands before convection surrounding the system started to weaken due to land interaction.

[6] Early on December 28, RSMC Nadi reported that Tropical Disturbance 02F had developed within an area of moderate windshear, about 140 km (90 mi) to the southeast of Alofi on the island of Niue.

[13] On January 8, RSMC Nadi reported that Tropical Depression 04F had developed, about 465 km (290 mi) to the west of Papeete on the French Polynesian island of Tahiti.

[13] Over the next 24 hours, convection surrounding the system became increasingly displaced to the far east of the exposed low level circulation centre because of strong vertical wind shear.

[14] Late on January 8, RSMC Nadi reported that Tropical Disturbance 05F had developed within a trough of low pressure, about 460 km (285 mi) to the southeast of Apia, Samoa.

[15] Over the next few days the depression, remained near stationary over central parts of the country and caused widespread heavy rainfall and strong winds, over Fiji's Northern and Eastern divisions which lead to flooding.

On January 25, RSMC Nadi reported that a shallow tropical depression, had developed over the northern Lau Islands, within a weak surface trough of low pressure.

[34] As it moved across the South Pacific, earlier existing wind shear conditions lessened, and Jasmine began to strengthen at a faster rate.

Steadily intensifying, Erica reached peak intensity on February 8 as a Category 4 equivalent on the Saffir–Simpson hurricane scale, while beginning to show annular characteristics.

On March 25, RSMC Nadi reported that Tropical Disturbance 17F, had developed within a trough of low pressure about 100 km (60 mi) to the northwest of Rotuma.

On April 1 the Fijian government announced that at least three people had been killed and almost 4,000 forced into evacuation centers after record floods hit the island nation.

On March 31, RSMC Nadi reported that Tropical Depression 19F had developed about 410 km (255 mi), to the south of Honiara on the Solomon Island of Guadalcanal.

[50] As a result, the United States Military's Fleet Weather Center in Norfolk, Virginia, designated the system as Tropical Cyclone 18P and issued warnings using data from the FMS and MetService.

[50] Power to the main island of Viti Levu and Nadi International Airport had been cut as thousands of stranded tourists scrambled to leave for home.

Early on February 14, Tropical Depression 13F developed within an area of low vertical windshear about 850 km (530 mi) to the northwest of Nouméa, New Caledonia.

[54] Tropical Disturbance 15F developed in an area of moderate to high vertical windshear during March 19, about 580 km (360 mi) to the northwest of Nouméa, New Caledonia.

[56] Tropical Disturbance 16F developed along a surface trough of low pressure, to the northwest of Wallis and Futuna, in an area of weak vertical wind shear during March 22.

[57] Tropical Depression 18F developed within an area of high to moderate vertical wind shear during March 30, while it was located about 200 km (125 mi) to the northeast of Port Vila, Vanuatu.

[59] Over the next day the system moved south-eastwards, before it was last noted during March 31, while it was located about 185 km (115 mi) to the south-east of Port Villa, Vanuatu.

[57][60] The twentieth and final tropical disturbance of the season was first noted during April 9, while it was located to the south of an upper-level ridge of high pressure about 435 km (270 mi) to the north-west of Nouméa, New Caledonia.

[61] During that day the system slightly organised further as it moved south-eastwards, between New Caledonia's Loyalty and Grande Terre islands, before it was declared to be a tropical depression during April 10.
