A low began to develop to the southwest of Sumatra on 11 November 1983 in a poorly-defined monsoon trough lying east-west through the Indonesian Islands. Steered by upper-level northwesterly winds, the low moved in a southeast direction towards the vicinity of Cocos Island. Cyclone status was thought to be attained around 0000 UTC 13 November. A final gale warning to shipping was issued at 0500 UTC 13 November. Post-analysis showed that no gales were reported during the event and it is unlikely that the system ever achieved cyclonic strength due to the strong wind shear over the area. The low finally weakened on 14 November.
Pearl occurred west of 90°E when the Australian region extended to 80°E.
