GRDC South Rainfall history & climate driver tool

How to use

Watch this short video which explains how to use the local climate tool.

Along the top tabs, you can select different climate driver phases and time of year (eg select +IOD tab and then July to October) to explore how rainfall at your selected location has been influenced by each climate driver phase.

Pie Charts show locations you can select from. (Blue = Wettest Tercile, Yellow = Average Tercile, Red = Driest Tercile)

Scroll in and out to zoom on the map.

Click on an individual pie chart to see more detailed rainfall history and analysis for each location.

Keep an eye out for buttons for help and hints.


This rainfall analysis tool was developed as part of the GRDC South "Using Seasonal Forecasts" extension project (April 2018 - Feb 2020). See more about the project here

This tool aims to show longer term rainfall records for selected locations. It also seeks to show how the climate drivers such as El Nino-Southern Oscillation and Indian Ocean Dipole have influenced seasonal rainfall in the past.

The rainfall data dating back to 1900 are interpolated values from the Queensland Government's Department of Environment and Science SILO database. For more information please see SILO climate data.

The classification of ENSO and IOD years comes from:

Concepts for these graph styles are thanks to Peter Hayman, Dale Grey, Darren Ray, Graeme Anderson & CeRDI.
