During November and December, no significant tropical cyclones developed in or moved into the South Pacific basin.

Systems

Tropical Cyclone Atu

Tropical Cyclone Atu existed from December 27 to December 30.

Severe Tropical Cyclone Beti

During 30 January, a shallow tropical low developed over the south-eastern Coral Sea. Over the next couple of days the system gradually developed further as it moved westwards into the South Pacific basin.

Tropical Cyclone Harvey

During February 7, Cyclone Harvey moved into the basin from the Australian region as a category 2 tropical cyclone with 10-minute windspeeds of . During the next day, Harvey gradually weakened as it moved towards the southeast, before at 1800 UTC the JTWC and TCWC Nadi reported that Harvey had weakened below tropical cyclone intensity. The subsequent remnant low continued to move towards the south-southeast before it was last noted by the FMS on February 10, while it was located about to the east of New Caledonia.

Unnamed tropical cyclone

An unnamed tropical cyclone existed from February 20 to February 24.

Tropical Cyclone Cyril

During March 16, a shallow tropical depression developed within the monsoon trough of low pressure about to the northwest of Nadi, Fiji. Over the next day the system moved south-eastwards, but there was no evidence of the system developing, with only small changes observed on successive satellite images. However, the system was named Cyril by the FMS during March 17, after a couple of satellite images, revealed more prominent cloud banding and a larger convective overcast around the systems centre. The system subsequently peaked with 10-minute sustained winds of 45 knots during the next day, before it started to accelerate south-eastwards and rapidly weaken. The system was last noted during March 21, while it was located about

Cyril caused significant flooding within Fiji's Northern and Western divisions, with a peak of reported during March 18 within the town of Nadi, while a small storm surge of was observed within Nadi's bay on the same day.

Unnamed tropical cyclone

Another unnamed tropical cyclone existed from March 23 to March 30.

Other systems

During January 18, Tropical Cyclone Grace moved into the basin from the Australian region, where it lost its tropical characteristics and weakened below tropical cyclone intensity. The system subsequently moved westwards before it was last noted, to the south-east of New Caledonia during January 21.

The remnant low of Cyclone Ingrid moved into the basin during February 25, before it was last noted by TCWC Nadi during February 27, about to the northeast of Brisbane Australia.
