The Southern Hemisphere Tropical Cyclone Data Portal (previously named the Pacific Tropical Cyclone Data Portal) improves knowledge of past tropical cyclone activity in the Pacific Islands and East Timor by plotting tracks of cyclones in the South Pacific from 1969, allowing users to see the characteristics and paths of past tropical cyclone events. Meteorologists and stakeholders can use this tool to analyse the tracks of historical tropical cyclones and relate them to the impact on lives and infrastructure recorded on the ground.

• Relationship to other tools: The Southern Hemisphere Tropical Cyclone Data Portal and the Pacific Climate Change Data Portal are connected in the sense that daily rainfall data from the Pacific Climate Change Data Portal could be used to examine the impacts of a particular tropical cyclone that is available via the Tropical Cyclone Data Portal. 

The Southern Hemisphere Tropical Cyclone Data portal was originally developed through the Pacific Climate Change Science Program (PCCSP, 2009-2011). Further developments took place through the Pacific-Australia Climate Change Science and Adaptation Planning Programme, (PACCSAP) Project 1.1.5: Enhancing PCCSP tools for analysis of historical climate extremes and decision-support.
