• View the latest maps and historical data.

The figures shown are the percentage of normal mean rainfall (i.e. 100% is normal) for physical rain gauges in our network. The derived rainfall for the complete region is achieved by applying a Thiessen interpolation between the closest surrounding gauges and as such is indicative only.

Normal rainfall is determined using the full period of record from a site until the end of the 2015 year. Users should note that different lengths of record are available from each station, which makes direct comparison between sites difficult in some cases. Refer to the station details page for each site to identify the length of record available for a site.
