The Bureau of Meteorology reported that in 2022, New South Wales experienced its second wettest year on record, with rainfall 55% above average for the state. Many sites recorded their highest annual rainfall totals on record. The state also experienced the coolest daytime temperatures since 1992, with maximum temperatures 0.48°C below the long-term climate average. Nights were warmer, with minimum temperatures 0.73°C above the long-term climate average.
The wet and cool daytime conditions in NSW in 2022 would have contributed to the improved air quality experienced across the state, by reducing the frequency and intensity of dust storms, bushfires and wind erosion events. Warmer than average winter minimum temperatures would have contributed to a reduction in smoky nights in regional areas from domestic wood heaters. There were also fewer hazard reduction burns in the year.
