The maps displayed on this page show areas of Australia that have experienced remarkably cold, hot or wet conditions on the day that you select. In other words, the maps show areas of Australia where temperature or rainfall records were either broken or nearly broken on a particular day, for that month. Read more
Note: The extremes maps are calculated by comparing the rainfall and temperature observations on the date you select with all the rainfall and temperature data for that particular month, not the whole climate record.
How to read the maps
The maps displayed on this page are percentile maps. Percentile analysis is a way of determining how unusual a rainfall or temperature event is. To determine whether a temperature or rainfall observation is unusual for a particular month, it is compared with all other rainfall and temperature daily observations in the same month in the climate record. All the observations for that month are ranked in order, from coolest to hottest for temperature, and driest to wettest for rainfall and then broken into 100 equal groups. The first group is the 1st percentile, the second group the 2nd percentile and so on. Read more
