The 1973–74 South Pacific cyclone season was an inactive season. In tropical cyclones, it was an average season, but in strength, it was very inactive, with only two severe tropical cyclones.

Systems

Tropical Cyclone SP7301

Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
DurationNovember 7 – November 11
Peak intensity65 km/h (40 mph) (10-min);
990 hPa (mbar)

Severe Tropical Cyclone Natalie-Lottie

Category 3 severe tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
DurationDecember 1 – December 11
Peak intensity120 km/h (75 mph) (10-min);
965 hPa (mbar)

This storm formed as Natalie, then moved into the Australian region the same day. Later it moved back into the SPac and was renamed Lottie. High seas caused the ship Uluilakeba to capsize killing more than 85 people. This makes Lottie one of the deadliest tropical cyclone in region in recent decades.

Tropical Cyclone Monica

Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
DurationJanuary 15 – January 20
Peak intensity65 km/h (40 mph) (10-min);
990 hPa (mbar)

Tropical Cyclone Nessie

Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
DurationJanuary 17 – January 22
Peak intensity65 km/h (40 mph) (10-min);

Tropical Cyclone Vera

Category 2 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
DurationJanuary 21 – January 22
Peak intensity95 km/h (60 mph) (10-min);
985 hPa (mbar)

Severe Tropical Cyclone Pam

Category 4 severe tropical cyclone (Australian scale)
 
DurationJanuary 30 – February 8
Peak intensity195 km/h (120 mph) (10-min);

Category 1 tropical cyclone (Australian scale)
 
DurationFebruary 19 – February 28
Peak intensity75 km/h (45 mph) (10-min);
988 hPa (mbar)

Rebecca was thought to have had a complex evolution with two low-level circulation centres. It had peak 10-minute sustained windspeeds of 75 km/h (45 mph) and a minimum pressure of 988 hPa (29.18 inHg), before it dissipated during February 28.
