Perth - Extreme Daily Rainfall for Each Year
This page lists the heaviest rainfalls and wettest days of each year in Perth, Western Australia. The information answers questions like: When was the last time Perth got more than three millimetres of rain in a single day? What was the heaviest rainfall of 2018 or a century ago?
The list gives the highest daily precipitation for each year in Perth and the date that it happened. A date with a plus sign beside it means the same amount of rain also fell on at least one other day earlier that year.
These records go back to 1880. During that time the heaviest downpour measured for a single day was 132.1 millimetres (5.2 inches) on February 9, 1992.
Since 1945 the rainfall extremes were observed at Perth Airport. Before then, the weather station was in downtown Perth.
