The 1978–79 South Pacific cyclone season ran year-round from July 1 to June 30. Tropical cyclone activity in the Southern Hemisphere reaches its peak from mid-February to early March.
Summary
Systems
Tropical Cyclone Fay
| Category 2 tropical cyclone (Australian scale) | |
| Tropical storm (SSHWS) | |
  | |
| Duration | December 27 – December 31 |
|---|---|
| Peak intensity | 100 km/h (65 mph) (10-min); 980 hPa (mbar) |
The precursor to Tropical Cyclone Fay can be traced back to an area of disturbed weather about 400 mi (640 km) to the west of Tuvalu early on December 25.[1] As it moved southeastward, it intensified into a tropical cyclone by the next day, before moving close to Rotuma by December 28 and reaching peak intensity the following day.[1][2] The cyclone then moved through Fiji, where sustained winds were pushing at 60 kn (110 km/h; 69 mph) with hurricane-force wind gusts. Once through the islands, Fay accelerated southwards, and was last noted on December 31 as it was becoming extratropical northeast of New Zealand.[3][2]
Weather stations at Undu Point and Savusavu recorded winds of 60 kn (110 km/h; 69 mph) as Fay passed through Fiji. Some of the Lau Islands suffered coastal damage from storm surge.[1]
Severe Tropical Cyclone Gordon
| Category 3 severe tropical cyclone (Australian scale) | |
| Category 1 tropical cyclone (SSHWS) | |
  | |
| Duration | January 3 – January 9 (Exited basin) |
|---|---|
| Peak intensity | 130 km/h (80 mph) (10-min); 965 hPa (mbar) |
Gordon was first tracked on January 3, when it was about 90 mi (140 km) to the north-northeast of the island of Tokelau. As it moved in a general southeastward direction, it strengthened into a tropical cyclone by the next day, before becoming a severe tropical cyclone by January 6. Then, it crossed to the north of Vanuatu with winds of 70 kn (130 km/h; 81 mph), before weakening into a tropical cyclone by January 7. It later approached New Caledonia while continuing to weaken on January 8, before it turned to the west, and subsequently exited the basin on January 9.[4] Severe damage was reported in Vanuatu.[5]
Tropical Cyclone Henry
| Category 2 tropical cyclone (Australian scale) | |
| Tropical storm (SSHWS) | |
  | |
| Duration | January 29 – February 5 |
|---|---|
| Peak intensity | 100 km/h (65 mph) (10-min); 980 hPa (mbar) |
Forming to the north of Vanuatu on January 29, Henry strengthened into a tropical cyclone on January 31, and took a southward track before becoming an extratropical cyclone and moving over New Zealand by February 4.[6] It had little affect to land areas in Vanuatu.[5]
Tropical Cyclone Judith
| Category 2 tropical cyclone (Australian scale) | |
| Tropical storm (SSHWS) | |
 | |
| Duration | February 3 – February 6 |
|---|---|
| Peak intensity | 95 km/h (60 mph) (10-min); |
Originating in the Australian region, Judith became a tropical cyclone as it moved close to Vanuatu, before turning west and re-entering the region by February 6.[7][8] Like Henry, it also had little affect to land areas in Vanuatu.[5]
Severe Tropical Cyclone Kerry
| Category 3 severe tropical cyclone (Australian scale) | |
| Category 2 tropical cyclone (SSHWS) | |
  | |
| Duration | February 13 – February 15 (Exited basin) |
|---|---|
| Peak intensity | 140 km/h (85 mph) (10-min); 978 hPa (mbar) |
Tropical Cyclone Kerry has the distinction of being the longest lived cyclone in the Australian region. It formed on February 13, 1979, and caused severe damage in the Solomon Islands. It then tracked across the Coral Sea making landfall near Mackay, Queensland on March 1 and dissipated on March 6. Its lowest pressure was 955hPa.[9]
Tropical Cyclone Leslie
| Category 2 tropical cyclone (Australian scale) | |
| Tropical storm (SSHWS) | |
| Duration | February 21 – February 23 |
|---|---|
| Peak intensity | 100 km/h (65 mph) (10-min); 980 hPa (mbar) |
Leslie existed from February 21 to February 23.
Severe Tropical Cyclone Meli
| Category 3 severe tropical cyclone (Australian scale) | |
| Category 4 tropical cyclone (SSHWS) | |
  | |
| Duration | March 24 – March 31 |
|---|---|
| Peak intensity | 155 km/h (100 mph) (10-min); 945 hPa (mbar) |
Cyclone Meli struck eastern Fiji on March 25. The island of Nayau suffered a direct hit and passed close to the islands of Lakeba and Cicia. Fiji suffered tremendous crop losses as a result of the storm.[10][11]
On March 27, 1979, Cyclone Meli brushed Fiji at peak intensity, causing substantial damage to the island. At least 50 people were killed by the storm.[11] Cyclone Meli had previously passed through Tuvalu damaging Funafuti atoll.
Tropical Cyclone Nina
| Category 1 tropical cyclone (Australian scale) | |
| Tropical storm (SSHWS) | |
  | |
| Duration | March 30 – April 1 |
|---|---|
| Peak intensity | 75 km/h (45 mph) (10-min); 994 hPa (mbar) |
Tropical Cyclone Nina formed near Vanuatu on March 31, and took a curving track to the southeast, dissipating near Tonga by March 3.[12][13] There were no particular damage reports associated with the storm.[5]
