NSW to brace for more record-breaking rainfall

Australia could be on track for a record year for climate records, with Bureau of Meteorology figures showing extraordinary results across all states and territories for every month of 2022 so far.
NSW has been smashed time and again, with rainfall records broken across the state every month except for June, and Greater Sydney breaking its all-time rainfall record in July.
Sydney has surpassed the total for its wettest year ever and, in February, the Wilsons River in Lismore broke previous flooding levels by more than two metres.
In July, 110 official weather stations across NSW registered monthly rainfall tallies above any previous record.
Other significant records could fall before the end of the year, with weather-watchers tracking rainfall tallies in Brisbane to see if it will follow Sydney in notching up its wettest year to date.
The Bureau of Meteorology forecast above-median rainfall for most of the eastern half of Australia until January, with the highest probabilities occurring in November.
If you think about record-breaking years, 2019 was our hottest and driest year on record; it has been quite the swing in the intervening 36 months since.

In addition to the La Nina and negative Indian Ocean Dipole climate drivers affecting Australia in 2022, the country has also been affected by a weather phenomenon called the Southern Annular Mode.
"Depending on how close those winds are to Antarctica or how close they are to Australia, they can also influence rainfall. We've seen that in a positive state for quite prolonged periods this year," Ms Osborne added.
