Sydney - Extreme Daily Rainfall for Each Year





This page lists the heaviest rainfalls and wettest days of each year in Sydney, New South Wales Australia. The information answers questions like: When was the last time Sydney got more than 100 millimetres of rain in a single day? What was the heaviest rainfall of 2018?

The list gives the highest daily precipitation for each year in Sydney 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 were observed at Sydney's Observatory Hill Park and go back to 1859. During that time the heaviest downpour measured for a single day was 327.7 millimetres (12.90 inches) on August 6, 1986.
